Use the Python string replace() function to change characters in a string. It will change all occurrences of a character old with the desired character new.
Example how to change a character in a string Python
Simple example code changing multiple occurrences of the character anywhere in the given string.
a_string = "axayza Hello" res = a_string.replace("a", "T") print(res)
Using slicing and concatenation:
s = "Hello, world!" index_to_change = 7 new_character = 'W' modified_string = s[:index_to_change] + new_character + s[index_to_change + 1:] print(modified_string)
Converting the string to a list, modifying the list, and then converting it back to a string:
s= "Hello, world!" index_to_change = 7 new_character = 'W' string_list = list(s) string_list[index_to_change] = new_character modified_string = ''.join(string_list) print(modified_string)
Remember that strings are immutable, so each of these methods creates a new string with the desired change rather than modifying the original string directly.
How to change one character in a string in Python?
Answer: Use list indexing to modify the one character in a string in Python. After change use join(iterable) with the empty string “” as a string and the modified list as iterable to construct a modified string.
a_string = "zbc" l = list(a_string) l = "a" res = "".join(l) print(res)
