Replacing string element in for loop Python

Question

I am reading data in from a text file so each row is a list of strings, and all those lists are in a data list. So my lists look like:

data = [row1, row2, etc.]
         


        

Answer 1

Also in your in this case you can use list comprehension

data = [[item.replace("%", "").replace("$", "0") for item in row] for row in data]
