    using python functionals (No regex)

    extname = s[compsep+1:]

if not (username and compname and extname):
    return False
if not (username == ''.join(list(filter(lambda c: c.isalnum() or c in '_,-', username)))):
    return False
if not (compname == ''.join(list(filter(lambda c: c.isalnum(), compname)))):
    return False
if not (extname == ''.join(list(filter(lambda c: c.isalnum(), extname))) and len(extname) <= 3):
    return False
return True
