Hi,I found a typo in the following address, at the bottom:http://docs.python.org/library/string.html string.replace(str, old, new[, maxreplace])Should read: string.replace(old, new[, maxreplace])Thanks for all the work and effort you put into making Python better and better.Best regards,Ramon Royo i GinerEstudiant de Grau Multimèdiarroyog@uoc.edu
