[Tutor] python help.. dictionary.

[Yaj Lis]

hello .. i'm new too python.. and programming..and learning slowly...

i'm creating a bank teller program. It has a list and dictionary.
It askes for the user's input (raw_input) asking for an amount. If the user 
enters letters instead of an amount it would count it as 'counterfiet'. 
Would i have to write a for loop function? how would i compare to see if it 
is a string or an interger?..and i can't figure out how to work it with the 
dictionary.. like if i put in $30.25.. it would return "you have 1 $20 bill, 
1 ten, and 1 quarter" .. i'm so frustrated.

here's what i have so far..

wallet=raw_input("money in wallet ")

for i in conterfeit(x):

bank={}
bank['h']=100
bank['F']=50
bank['T']=20
bank['t']=10
bank['f']=5
bank['o']=1
bank['q']=.25
bank['d']=.10
bank['p']=.01

x=wallet
counterfeit(x)


I want the program to output something like this...It should report the 
total value of the legal money as a floating point value (e.g. 123.45) and 
the total number of counterfeit pieces received.

Money in wallet: asdfasdf
Contained "1" counterfiet piece(s).
Total amount in bank $20.00

asking for any help? thanks a lot..
