Version 1 of Teller Machine program

# tellerMachine.py
# D. Thiebaut
# A program that simulates a teller machine, where user enters an amount of
# dollars, and program figures out the number of bills to return.

# get the amount 
amount = eval( input( "Please enter amount: " ) )
amount = int( amount )
print()

# break down into bills
no20s = amount // 20       # how many 20s go into amount
amount = amount % 20    # what is left over after giving out 20s go back into amount

no10s = amount // 10
amount = amount % 10

no5s = amount //5
no1s = amount % 5

# display the results
print( "Amount withdrawn = ", amount )
print( "Please lift your keyboard and find: " )
print( no20s, "$20-bill(s)" )
print( no10s, "$10-bill(s)" )
print( no5s, "$5-bill(s)" )
print( no1s, "$1-bill(s)" )


Version 2, submitted by Shirui Cheng, who figured out that it was a perfect opportunity to use a loop!

# Teller machine simulator
#

# get the input
amount = eval(input ("How much money do you want to withdraw? "))

# break down in $20-, $10-, $5-, and $1-bills
for bill in (20, 10, 5, 1):
    no = amount // bill
    amount = amount % bill
    print (no, "$", bill, "bill(s)")
