To replace a character in a string with another character in Python, you can use the string replace() function.
example_string = "This is a string."
string_with_i_replaced_with_e = example_string .replace("i","e")
print(string_with_i_replaced_with_e)
#Output:
Thes es a streng.When working with strings in Python, being able to manipulate your variables easily is important. There are a number of built in string methods which allow us to get information and change string variables.
One such function which is very useful is the string replace() function. With the replace() function, we can create a new string where the specified value is replaced by another specified value.
We can use the replace() function to replace a specific character in a string with another character.
To replace the i’s of a string with e’s, for example, we can use the replace() function in the following Python code.
example_string = "This is a string."
string_with_i_replaced_with_e = example_string .replace("i","e")
print(string_with_i_replaced_with_e)
#Output:
Thes es a streng.If you wanted to remove all occurrences of a character from a string, you can use a replacement value of an empty string.
example_string = "This is a string."
string_with_i_removed = example_string .replace("i","")
print(string_with_i_removed)

Below are a few more examples of how you can use the replace() function to make replacements in strings in Python.
For example, if we want to replace spaces with dashes, we can do the following.
string_with_spaces = "This is a string."
string_with_dashes = string_with_spaces.replace(" ","-")
print(string_with_dashes)
#Output:
This-is-a-string.If we want to replace all the spaces with periods, we can do so easily in the following Python code.
string_with_spaces = "This is a string."
string_with_periods = string_with_spaces.replace(" ","-")
print(string_with_periods)
#Output:
This.is.a.string.You can also replace full words with other words. Let’s replace the word “a” with “the”.
string_with_spaces = "This is a string."
string_with_the = string_with_spaces.replace("a","the")
print(string_with_the)
#Output:
This is the string.Hopefully this article has been useful for you to learn how to replace specific characters with other characters in a string in Python.
