Python String join() Method Examples

In the previous article, we have discussed Python Program for isdigit() Function
String join() Function in Python:

The join() method joins all items in an iterable into a single string.

As the separator, a string must be specified.

Syntax:

string.join(iterable)

Parameters:

iterable: This is required. Any iterable object whose returned values are all strings.

Examples:

Example1:

Input:

Given list = ['welcome', 'to', 'python', 'programs']
Given separator = '@'

Output:

The given list items after applying join() function :  welcome@to@python@programs

Example2:

Input:

Given tuple = ('hello', 'all', 'good', 'morning')
Given separator = '-'

Output:

The given tuple items after applying join() function :  hello-all-good-morning

Method #1: Using Built-in Functions (Static Input)

Approach:

Give the list as static input and store it in a variable.
Give the tuple as static input and store it in another variable.
Give the set as static input and store it in another variable.
Give the first separator as static input and store it in another variable.
Give the second separator as static input and store it in another variable.
Give the third separator as static input and store it in another variable.
Apply join() function to the given list to joins all items in a list into a single string for the given separator1.
Store it in another variable.
Apply join() function to the given tuple to joins all items in a tuple into a single string for the given separator2.
Store it in another variable.
Print the result string after joining the given list items using the join() function.
Print the result string after joining the given tuple items using the join() function.
Similarly, do the same for the given set with the given third separator and print the result string.
The Exit of Program.

Below is the implementation:

# Give the list as static input and store it in a variable.
gvn_lst = ['welcome', 'to', 'python', 'programs']
# Give the tuple as static input and store it in another variable.
gvn_tupl = ('hello', 'all', 'good', 'morning')
# Give the set as static input and store it in another variable.
gvn_set = ('This', 'is', 'python', 'learning', 'platform')
# Give the first separator as static input and store it in another variable.
gvn_sepatr1 = '@'
# Give the second separator as static input and store it in another variable.
gvn_sepatr2 = '-'
# Give the third separator as static input and store it in another variable.
gvn_sepatr3 = '#'
# Apply join() function to the given list to joins all items in a list into a
# single string for the given separator1.
# Store it in another variable.
rsltstrng1 = gvn_sepatr1.join(gvn_lst)
# Apply join() function to the given tuple to joins all items in a tuple into a
# single string for the given separator2.
# Store it in another variable.
rsltstrng2 = gvn_sepatr2.join(gvn_tupl)
print("The given list items after applying join() function : ", rsltstrng1)
print("The given tuple items after applying join() function : ", rsltstrng2)
# Similarly, do the same for the given set with given third separator and
# print the result string
rsltstrng3 = gvn_sepatr3.join(gvn_set)
print("The given set items after applying join() function : ", rsltstrng3)

Output:

The given list items after applying join() function :  welcome@to@python@programs
The given tuple items after applying join() function :  hello-all-good-morning
The given set items after applying join() function :  This#is#python#learning#platform

Method #2: Using Built-in Functions (User Input)

Approach:

Give the list as user input using list(), input(), and split() functions.
Store it in a variable.
Give the tuple as user input using list(), input(), and split() functions.
Store it in another variable.
Give the set as user input using list(), input(), and split() functions.
Store it in another variable.
Give the first separator as user input using the input() function and store it in another variable.
Give the second separator as user input using the input() function and store it in another variable.
Give the third separator as user input using the input() function and store it in another variable.
Apply join() function to the given list to joins all items in a list into a single string for the given separator1.
Store it in another variable.
Apply join() function to the given tuple to joins all items in a tuple into a single string for the given separator2.
Store it in another variable.
Print the result string after joining the given list items using the join() function.
Print the result string after joining the given tuple items using the join() function.
Similarly, do the same for the given set with the given third separator and print the result string.
The Exit of Program.

Below is the implementation:

# Give the list as user input using list(),input() and split() functions.
# Store it in a variable.
gvn_lst = list(input(
    'Enter some random List Elements separated by spaces = ').split())
# Give the tuple as user input using list(), input(),and split() functions.
# Store it in another variable.
gvn_tupl = tuple(input(
    'Enter some random Tuple Elements separated by spaces = ').split())
# Give the set as user input using list(), input(),and split() functions.
# Store it in another variable.
gvn_set = set(input(
    'Enter some random Set Elements separated by spaces = ').split())
# Give the first separator as user input using the input() function and 
# store it in another variable.
gvn_sepatr1 = input("Enter a random element = ")
# Give the second separator as user input using the input() function and 
# store it in another variable.
gvn_sepatr2 = input("Enter a random element = ")
# Give the third separator as user input using the input() function and 
# store it in another variable.
gvn_sepatr3 = input("Enter a random element = ")
# Apply join() function to the given list to joins all items in a list into a
# single string for the given separator1.
# Store it in another variable.
rsltstrng1 = gvn_sepatr1.join(gvn_lst)
# Apply join() function to the given tuple to joins all items in a tuple into a
# single string for the given separator2.
# Store it in another variable.
rsltstrng2 = gvn_sepatr2.join(gvn_tupl)
# Print the result string after joining the given list items using the join()
# function
print("The given list items after applying join() function : ", rsltstrng1)
# Print the result string after joining the given tuple items using the join()
# function
print("The given tuple items after applying join() function : ", rsltstrng2)
# Similarly, do the same for the given set with given third separator and
# print the result string
rsltstrng3 = gvn_sepatr3.join(gvn_set)
print("The given set items after applying join() function : ", rsltstrng3)

Output:

Enter some random List Elements separated by spaces = hello this is python learning platform
Enter some random Tuple Elements separated by spaces = p r q s t
Enter some random Set Elements separated by spaces = good morning all
Enter a random element = &
Enter a random element = *
Enter a random element = !
The given list items after applying join() function : hello&this&is&python&learning&platform
The given tuple items after applying join() function : p*r*q*s*t
The given set items after applying join() function : good!morning!all
