What are Lists?

If you’re conversant in the C programming language, then you definitely might need heard about arrays. Lists are just about like arrays besides that they’ll include any knowledge sort, not like arrays. A listing is a set of objects which might be ordered. Additionally, every ingredient within the listing is listed based on a particular sequence, and a listing’s indexing is finished with 0 being the primary index.

The listing is a ‘Assortment Datatype’ that may include integers, strings, or different lists too. Lists are mutable, therefore, they are often modified even after their creation. Additionally, notice that lists can include duplicate entries, not like units. Python lists might be created within the following means:

EmptyList=[] #EmptyList
listOfnumbers=[1,3,56,78] #Record of numbers
listOfObjects=[1,"anything",["lists","in","lists"],2.5] # Record containing totally different knowledge varieties

What are ‘Strings’?

So, what precisely are strings? Strings are one of many knowledge varieties in Python and might be outlined as a sequence of characters. There’s a built-in class ‘str’ for dealing with a Python string. Creating strings is so simple as assigning a worth to a variable. For instance −

first_name=""'Ted '''
middle_name="Evelen "#generally used technique
last_name="Mosby"#generally used technique

Strive it your self. Let’s make some Names

As might be seen within the instance above, there are 3 ways by which we will create a string. Though double quotes and single quotes are extra typically used than triple quotes, what if the string accommodates a single quote or double quotes? Allow us to discover out within the instance beneath.

string_1="Good day "Python" "
string_1='Good day "Python"'
string_2='Let's go to the park'
string_2="Let's go to the park"
string_3='''Let's go the "PARK"'''

Within the above instance, we realized tips on how to keep away from such errors, now shifting on to the query “tips on how to convert a listing to a string?”

Convert Record to String

A number of strategies can be utilized to transform a listing to a string.

Methodology 1

By utilizing the in-built technique of python .be a part of()

print(" ".be a part of(Title))#used an area to separate listing components right here.
College students=["Barney","Robin","Lily"]
print("n".be a part of(College students))

Strive some Conversions Your self

NOTE: If the listing accommodates any non-string ingredient, the above technique doesn’t work until we use map() perform to transform all components to a string first. Let’s see an instance:

print(" ".be a part of(map(str,test_list)))

Click on right here and observe 

Methodology 2

Utilizing the str() technique 

#Now manipulate the str() to get string of simply Numbers
#or we will use strip perform to get jsy Numbers

Check out your self. Click on right here 

Methodology 3

Utilizing the Record comprehension technique

listToStr=" ".be a part of([str(element) for element in test_list ]) 

Click on Right here and Run it your self

Methodology 4

Utilizing Be part of Perform

Python comes with an inbuilt perform JOIN(), to transform a listing right into a string. The be a part of () perform combines the weather of a listing utilizing a string separator. It is without doubt one of the easiest methods to transform a listing right into a string utilizing Python. Nonetheless, it must be saved in thoughts that it solely converts a listing right into a string when the listing accommodates string components in it. a part of(name_of_list)

Now to know the perform higher, let’s see an instance beneath:

my_list = [‘how’, ‘to’, ‘convert’, ‘into’, ‘string’]

‘ ‘.be a part of(listing)


‘tips on how to convert into string’

Within the instance above, the listing accommodates string components in it and the subsequent line is used to transform it right into a single string utilizing the be a part of perform. The clean house utilized in single quotes earlier than initiating the be a part of perform is used to present an area between the gadgets of a listing. 

Now, suppose if the listing doesn’t include a string and you continue to have to convert it into the string, then how will you do it?

Let’s see it in one other instance:

my_list = [1,3,5,7,9]

‘ ‘.be a part of(str (e) for e in listing)


‘1 3 5 7 9’

Right here the datatype was totally different as the weather weren’t strings, and subsequently, we would have liked to transform them into the listing first utilizing the str() perform with an iterable over all components of the listing utilizing for loop. This manner, it transformed it into particular person strings first after which transformed right into a single string. 

Methodology 5

Traversal of a Record Perform

That is one other technique of changing a listing right into a string by traversing via every ingredient within the string utilizing for loop and mixing it with the earlier ingredient till the listing turns into empty. And eventually, it returns a single string as an output. See the instance beneath to know the idea extra clearly.


my_list = [‘learn’, ‘with’, ‘great’, ‘learning’, ‘academy’]

single_string = ‘ ‘

for i in my_list:
	single_string += ‘ ‘ + i



study with nice studying academy

Within the above instance, the for loop iterated via every ingredient within the listing and concatenated in a single string which was our ultimate end result. 

Methodology 6

Utilizing map() Perform

There might be two attainable situations the place you need to use the map() perform to transform a listing to a string. These two instances embody when the listing has solely numbers and the opposite if the listing is heterogeneous. See an instance beneath:

my_list = [‘Hi’, ‘Ashu’, ‘how’, ‘are’, ‘you’, ‘?’]

str_ing = ‘ ‘.be a part of(map(str, my_list))



Hello Ashu how are you ?

Right here the map perform wants two arguments, such that the primary is the datatype the place you have to give str to transform right into a string, and the opposite is the title of the listing. Now, the map perform first calls every ingredient in an iterable sequence utilizing the str() perform that converts every ingredient right into a string. Lastly, the be a part of perform combines every ingredient right into a single string. 

Methodology 7

Iterating Via the Record

This technique could be very easy, the place we simply have to traverse via every ingredient within the listing utilizing for loop and including every ingredient to our string variable. See the python code beneath for a greater understanding:

my_list = [‘Hi’, ‘Ashu’, ‘How’, ‘are’, ‘you’, ‘?’]

my_string = “”

for x in my_list:

my_string += x + ‘’



Hello Ashu How are you ?

Convert a listing of integers right into a single integer

Given a listing of integers like [1,2,3], Can we convert it right into a single integer, 123? Positive we will.

Let’s discover out some strategies to take action

Methodology 1

Utilizing the be a part of() technique of Python

We will use the be a part of () technique and the inbuilt int() in Python. Allow us to see some examples to know higher.

list_1 = [1, 2, 3]
numbers_str = [str(i) for i in list_1] #Utilizing listing comprehension 
#Now that the weather have been transformed to strings we will use the be a part of technique
quantity= int("".be a part of(numbers_str)) #convert ultimate string to integer

Check out some examples your self. Click on right here

Methodology 2

The second technique is rather more naive and is finest suited once we wish to simply show the quantity as an alternative of storing it in a variable as proven in technique 1. Allow us to see how to do that:

list_1 = [12, 15, 17] 
# iterating every ingredient 
def toNumber(anyList):
    for i in anyList: 
        print(i, finish="")
    print("")#This print assertion by default prints a brand new line
#Be aware that the quantity isn't saved anyplace.

Click on Right here and Apply with the above code

Convert String to Record

As we’ve got seen other ways to transform a listing to a string. Now, we are going to perceive to transform a string to a listing in python. There are numerous methods to transform a string in Python. 

Conversion of 1 knowledge sort to different might be carried out utilizing python. However changing string to listing isn’t so simple as an information sort conversion. Some widespread listing conversion strategies are break up() and listing(). Allow us to see each of those strategies to transform a string to a listing.

Utilizing Cut up():

The break up() technique could be very helpful that dividing the string based mostly on a specified delimiter. Such that the string is split and saved in a listing. The built-in technique of python is used to return a listing of phrases within the string with the assistance of a specified delimiter. 


my_string.break up(delimiter, maxsplit)

Listed here are the parameters: delimiter and max break up are non-compulsory, the place should you don’t specify delimiter, then it would routinely take white house as a delimiter, and max break up is used to separate most instances. You can even specify the variety of splits that you simply wish to perform within the string. 


my_string = “Hello Nice Learner how are you doing”
my_list = my_string.break up()


[‘Hi’, ‘Great’, ‘Learner’, ‘how’, ‘are’, ‘you’, ‘doing’]


Right here, we didn’t specify the delimiter and max break up. Subsequently, it took the default delimiter as white house and did the break up of the entire string. 

Utilizing listing():

This technique can be used to transform a string to a listing. This is without doubt one of the most typical methods to transform a string. Nonetheless, we suggest utilizing this technique solely whenever you wish to break up the string into a listing of characters. The listing technique divides the string into characters. See the instance beneath to know it fully. 


my_string = “Convert string to listing of characters”
my_list = listing(my_string.strip(“ “))


[‘C’, ‘o’, ‘n’, ‘v’, ‘e’, ‘r’, ‘t’, ‘ ‘, ‘s’, ‘t’, ‘r’, ‘i’, ‘n’, ‘g’, ‘ ‘, ‘t’, ‘o’, ‘ ‘, ‘l’, ‘i’, ‘s’, ‘t’, ‘ ‘, ‘o’, ‘f’, ‘ ‘, ‘c’, ‘h’, ‘a’, ‘r’, ‘a’, ‘c’, ‘t’, ‘e’, ‘r’, ‘s’]

Rationalization: Right here, the string is split into characters and saved in a listing variable. It may be seen that white house can be taken as a single character within the string. 

We will use the in-built perform break up() to transform a string to a listing. Allow us to see some examples:

string_1="Allow us to convert string to listing"
print(string_1.break up(" "))# Right here we specified " " as delimiter
#Primarily based on the required delimiter the listing string will probably be sepatrated
string_2="Let*us*convert*string to*listing"
print(string_2.break up())#By default delimiter is house " "
print(string_2.break up("*"))#Right here we specified * because the  delimiter

Check out the code your self

Within the final line of output, it may be seen that the ingredient ‘string to’ isn’t separated. The reason is that the delimiter specified is asterisk ‘*’ not house “ ”.

Convert String to Record of characters

As mentioned above, a String is a sequence of characters. We will convert it to the listing of characters utilizing listing() built-in perform. When changing a string to a listing of characters, whitespaces are additionally handled as characters. Additionally, if there are main and trailing whitespaces, they’re part of the listing components too.

Allow us to see some examples:

string_1=' Nice! *^& '

Strive the code above. Click on right here to observe

The strip perform is used to depart out all main and trailing whitespace, however the areas within the center are usually not disregarded.

Convert a listing of characters right into a string

Changing a listing of characters right into a string is sort of much like changing a listing of integers right into a quantity which is already proven above. So allow us to see how it’s carried out

To transform a listing of characters like [g,r,e,a,t] right into a single string ‘nice’,we use the be a part of() technique as proven beneath

string1=''.be a part of(chars)
