Using Python to Remove Commas from String

To remove commas from a string using Python, the easiest way is to use the Python replace() function.

string_with_commas = "This, is, a, string, with, commas."

string_without_commas = string_with_commas.replace(",","")

print(string_without_commas)

#Output:
This is a string with commas.

You can also use a regular expression to remove quotes from a string.

import re

string_with_commas = "This, is, a, string, with, commas."

string_without_commas = re.sub(",",'',string_with_commas)

print(string_without_commas)

#Output:
This is a string with commas.

When using string variables in Python, we can easily perform string manipulation to change the value of the string variables.

One such manipulation is to remove characters from a string variable. Commas can sometimes be troubling characters to deal with in string variable, but we can easily remove commas from a string in Python.

The easiest way to get rid of commas in a string using Python is with the Python string replace() function.

The replace() function takes two arguments: the substring we want to replace, and the replacement substring. In this case, to remove quotes, we pass the comma (“,”) character as the first argument, and an empty string as the second argument.

Below are some examples of how you can remove commas from string variables in Python using the replace() function.

string_with_commas = "This, is, a, string, with, commas."

string_without_commas = string_with_commas.replace(",","")

print(string_without_commas)

#Output:
This is a string with commas.

Using Regular Expressions to Remove Commas from Strings in Python

Another way you can remove commas from strings in Python is with regular expressions.

With the regular expression re module in Python you can remove commas from a string easily.

We can easily define a regular expression which will search for commas, and then using the sub() function, we will replace those commas with spaces.

Below is an example of how to use regular expressions to remove commas from a string using Python.

import re

string_with_commas = "This, is, a, string, with, commas."

string_without_commas = re.sub(",",'',string_with_commas)

print(string_without_commas)

#Output:
This is a string with commas.
