I'm trying to print out floats in currency format, but no matter what numbers I specify for rounding parameters, it only prints out one 0 after the decimal point:

#!/usr/bin/env python3
#FormattingStuff.py

def listOfFloats():
    floatsList = [20.0007, 20.00, 3.00, 5.780001]
    print("$" + str(round(floatsList[1], 2)))
    print("$" + str(round(floatsList[1], 3)))

def main():
    listOfFloats()

main()

The output is:

Error:
======= RESTART: I:/Python/Python36-32/SamsPrograms/FormattingStuff.py =======
$20.0
$20.0
>>> 

Why are they the same? I'm trying to output $20.00

round is doing the rouding mathematically, so if last decimal(s) is zero(es) it will omit them from printing. Try with the format method instead:

print('${:.2f}'.format(round(floatsList[1], 2)))
