My Code:

def exact$\_$change$($user$\_$total$)$:

num$\_$dollars$=$ user$\_$total$//100$

user$\_$total $=$ user$\_$total $\%100$

num$\_$quarters $=$ user$\_$total $//25$

user$\_$total $=$ user$\_$total $\%25$

num$\_$dimes $=$ user$\_$total $//10$

user$\_$total $=$ user$\_$total $\%10$

num$\_$nickels $=$ user$\_$total $//5$

user$\_$total $=$ user$\_$total $\%5$

num$\_$pennies $=$ user$\_$total

return num$\_$dollars, num$\_$quarters, num$\_$dimes, num$\_$nickels, num$\_$pennies

if $\_\_$name$\_\_==\text{'}\_\_$main$\_\_\text{'}$:

input$\_$val $=$ input$()$

num$\_$dollars, num$\_$quarters, num$\_$dimes, num$\_$nickels, num$\_$pennies $=$ exact$\_$change$($input$\_$val$)$

if $($input$\_$val $<=0)$:

print$(\text{'}$no change'$)$

if $($input$\_$val $==$ exact$\_$change$(300)$:

print$(\text{'}3$ dollars'$)$

else:

if num$\_$dollars $==1$:

print$($num$\_$dollars, 'dollar'$)$

elif num$\_$dollars $>1$:

print$($num$\_$dollars, 'dollars'$)$

if num$\_$quarters $==1$:

print$($num$\_$quarters, 'quarter'$)$

elif num$\_$quarters $>1$:

print$($num$\_$quarters, 'quarters'$)$

if num$\_$dimes $==1$:

print$($num$\_$dimes, 'dime'$)$

elif num$\_$dimes $>1$:

print$($num$\_$dimes, 'dimes'$)$

if num$\_$nickels $==1$:

print$($num$\_$nickels, 'nickel'$)$

elif num$\_$nickels $>1$:

print$($num$\_$nickels, 'nickles'$)$

if num$\_$pennies $==1$:

print$($num$\_$pennies, 'penny'$)$

elif num$\_$pennies $>1$:

print$($num$\_$pennies, 'pennies'$)$

When the input becomes 'exact$\_$change$(300)\text{'},$ my code produces no output
