Hi again, I'm allways here to ask how to use regular expressions. what I want now is to replace chars from a string with empty spaces sample = "thi's is a tes<>%$#!|t" what I want is use sample.sub(\['<>%$#!|]\,"") and the outcome shoudl be "this is a test" But I only can replace the first occurence of the chars specified in the reg exp How can I replace all occurences?
