HELP: compile error, cannot import python package re for regex

  • 0

    this does not compile:

    def isAlphanumeric(self, a):
        import re
        return re.match(r'^[a-zA-Z0-9]$', a) != None

    yet this does:

    def isAlphanumeric(self, a):
        return len(a) == 1 and a in 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'

    seem we cannot import regex package, is it general that we cannot export any library?

    Try remove the line of import, it seems that the collections are automatically imported.
    It worked for me!

    Agree. Same thing on string.
