How can I get the right calculations for the total of the coin change calculator?

Question

I am new at programming and I want to get better at it. I am working on a change calculator that accepts five arguments(dollars, quarters, dimes, nickels, pennies) and calculates the total amount of change. When I put change.py in the command line followed by 1 1 1 1 1 I am supposed to get 1.41 as the total but I am getting 1.95. Can anyone help with this? Thank you!

import sys

   
def change(dollars,quarters,dimes,nickels,pennies):
 
    dollars = int(float(dollars))
    quarters = int(float(quarters))
    dimes = int(float(dimes))
    nickels = int(float(nickels))
    pennies = int(float(pennies))

    total = (dollars * 100) + (quarters * 0.25 ) + (dimes * 0.10) + (nickels * 0.5) + (pennies * 0.1)

dollars = sys.argv[1]
quarters = sys.argv[2]
dimes = sys.argv[3]
nickels = sys.argv[4]
pennies = sys.argv[5]

      

print('The total value of your change is ',(total)) 

change(dollars,quarters,dimes,nickels,pennies)

With the code you have you need to ensure you are passing those arugments in the command line when you run your code:

python coinprogram.py 1 2 3 4 5

I also noticed the change is not being calculated correctly try this out:

import sys


dollars = sys.argv[1]
quarters = sys.argv[2]
dimes = sys.argv[3]
nickels = sys.argv[4]
pennies = sys.argv[5]


def change(dollars, quarters, dimes, nickels, pennies):

    dollars = int(float(dollars))
    quarters = int(float(quarters))
    dimes = int(float(dimes))
    nickels = int(float(nickels))
    pennies = int(float(pennies))

    return ((dollars * 100) + (quarters * 25) + (dimes * 10) + (nickels * 5) + (pennies * 1)) / 100


total = change(dollars, quarters, dimes, nickels, pennies)
print('The total value of your change is ', (total))

if you would prefer to get user input within the program then you could do something like this instead:

import sys


dollars = input("Enter dollars: ")
quarters = input("Enter quarters: ")
dimes = input("Enter dimes: ")
nickels = input("Enter nickels: ")
pennies = input("Enter pennies: ")


def change(dollars, quarters, dimes, nickels, pennies):

    dollars = int(float(dollars))
    quarters = int(float(quarters))
    dimes = int(float(dimes))
    nickels = int(float(nickels))
    pennies = int(float(pennies))

    return ((dollars * 100) + (quarters * 25) + (dimes * 10) + (nickels * 5) + (pennies * 1)) / 100


total = change(dollars, quarters, dimes, nickels, pennies)
print('The total value of your change is ', (total))
