Given a string and List, replace each occurrence of K word in string with random element from list.
Input : test_str = “Gfg is x. Its also x for geeks”, repl_list = [“Good”, “Better”, “Best”], repl_word = “x”
Output : Gfg is Best. Its also Better for geeks
Explanation : x is replaced by random replace list values.Input : test_str = “Gfg is x. Its also x for geeks”, repl_list = [“Good”, “Better”, “Nice”], repl_word = “x”
Output : Gfg is Best. Its also Nice for geeks
Explanation : x is replaced by random replace list values, “Best” and “Nice”.
Method #1 : Using shuffle() + loop + replace()
The combination of above functions can be used to solve this problem. In this, we replace each occurrence of K word with random string from list using replace().
Python3
# Python3 code to demonstrate working of # Random Replacement of Word in String # Using replace() + shuffle() + loop from random import shuffle # initializing string test_str = "Gfg is val. Its also val for geeks" # printing original string print("The original string is : " + str(test_str)) # initializing list repl_list = ["Good", "Better", "Best"] # initializing replace word repl_word = "val" # shuffing list order shuffle(repl_list) for ele in repl_list: # replacing with random string test_str = test_str.replace(repl_word, ele, 1) # printing result print("String after random replacement : " + str(test_str)) |
The original string is : Gfg is val. Its also val for geeks String after random replacement : Gfg is Best. Its also Better for geeks
Method #2 : Using list comprehension + replace() + shuffle()
This is one of the ways in which this task can be performed. In this, we encapsulate entire logic in one-liner using similar functionalities as above method.

# Python3 code to demonstrate working of # Random Replacement of Word in String # Using list comprehension + replace() + shuffle() from random import shuffle # initializing string test_str = "Gfg is val. Its also val for geeks" # printing original string print("The original string is : " + str(test_str)) # initializing list repl_list = ["Good", "Better", "Best"] # initializing replace word repl_word = "val" # one-liner to solve problem shuffle(repl_list) res = [test_str.replace(repl_word, ele, 1) for ele in repl_list] # printing result print("String after random replacement : " + str(res)) |
The original string is : Gfg is val. Its also val for geeks
String after random replacement : [‘Gfg is Good. Its also val for geeks’, ‘Gfg is Better. Its also val for geeks’, ‘Gfg is Best. Its also val for geeks’]
