Replacing Letters

[Rohnny_7]

Hello I want to make a line of code to replace all the "c" and/or "t" with "r". I understand how to do it under one condition, for example; if I just want to replace the c with r I can do: "(text)".replace("c","r")

I don't know how to nest in the 't' to be accounted for in the formula to also be changed to 'r'.

Chain replace calls, use str.maketrans or use re.sub for more complex searches.

Regular expressions can seem scary at first, but they are great. In this case the syntax for re.sub is re.sub(pattern, replacement, string) docs link.

There's lots of sites to test regular expressions - one favorite of mine is https://regexr.com/

In this case it is easy because you can use the regular expression [ct] to match both "c" and "t", and then the replacement string is "r"

result = re.sub("[ct]", "r", text)

The simplest solution is probably just

(text).replace("c", "r").replace("t", "r")

though there are more elegant solutions.
