Python program to split and join a string

Python program to Split a string based on a delimiter and join the string using another delimiter.

Split a string can be quite useful sometimes, especially when you need only certain parts of strings. A simple yet effective example is splitting the First-name and Last-name of a person. Another application is CSV(Comma Separated Files). We use split to get data from CSV and join to write data to CSV.

In Python, we can use the function split() to split a string and join() to join a string. For detailed article on split() and join() functions, refer these : split() in Python and join() in Python.

Examples :

Split the string into list of strings

Input : Geeks for Geeks
Output : ['Geeks', 'for', 'Geeks']


Join the list of strings into a string based on delimiter ('-')

Input :  ['Geeks', 'for', 'Geeks']
Output : Geeks-for-Geeks

Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Below is Python code to Split and Join the string based on a delimiter :

Python program to split a string and

join it using different delimiter

def split_string(string):

# Split the string based on space delimiter
list_string = string.split(' ')

return list_string

def join_string(list_string):

# Join the string based on '-' delimiter
string = '-'.join(list_string)

return string

Driver Function

if name == ‘main‘:
string = ‘Geeks for Geeks’

# Splitting a string
list_string = split_string(string)
print(list_string)

# Join list of strings into one
new_string = join_string(list_string)
print(new_string)

Output :

['Geeks', 'for', 'Geeks']
Geeks-for-Geeks
