There's a string method called capitalize, so you can use string_name.capitalize() In [27]: x = "rakaNishu" In [28]: x = x.capitalize() In [29]: x Out[29]: 'Rakanishu' > > 2.

Off the top of my head, you can build a new string while checking each character using another string method isalpha. You might want to check the string first before even bothering with the loop. i.e. if not string_name.isalpha()...then enter this loop below... In [38]: x = "rakan345ishu" In [39]: newx = "" In [40]: for chr in x: ....: if chr.isalpha(): ....: newx += chr ....: In [41]: print newx rakanishu Mike _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
