Version 1

# ATM_version1.py

# this program distributes some amount of dollars
# into bills and coins.
#
# Original amount
amount = 124.45

# transform into two integer amounts, one for bills, one for coins
bAmount = int( amount )
cAmount = int( amount * 100 ) % 100

print( "Distributing $" + str( amount ) )

# distribute amount in different denominations
no20s = bAmount // 20
bAmount = bAmount % 20

no10s = bAmount // 10
bAmount = bAmount % 10

no5s = bAmount // 5
no1s = bAmount % 5

# display resulting bill distribution 
print( no20s, "$20-bill(s)" )
print( no10s, "$10-bill(s)" )
print( no5s,  "$5-bill(s)" )
print( no1s,  "$1-bill(s)" )

# distribute coins into different quantities
no25s = cAmount // 25
cAmount = cAmount % 25

no10s = cAmount // 10
cAmount = cAmount % 10

no5s = cAmount // 5
no1s = cAmount % 5

# display resulting coin distribution 
print()
print( no25s, "quarter(s)" )
print( no10s, "dime(s)" )
print( no5s,  "nickel(s)" )
print( no1s,  "cent(s)" )

Output

>>> 
Distributing $124.45
6 $20-bill(s)
0 $10-bill(s)
0 $5-bill(s)
4 $1-bill(s)

1 quarter(s)
2 dime(s)
0 nickel(s)
0 cent(s)
