How to remove specific characters from a string in Python

To remove specific characters from a string in Python, you can use the str.replace() method or the str.translate() method. Here are some examples:

Using str.replace():

s = "Hello, world!"
s = s.replace(",", "")  # remove commas
print(s)  # "Hello world!"

Using str.translate():

s = "Hello, world!"
s = s.translate(str.maketrans("", "", ","))  # remove commas using translate
print(s)  # "Hello world!"

Both of these methods create a new string object rather than modifying the original string in place, since strings are immutable in Python.
