qtr = int(cents/25)

cents = cents -qtr * 25

nkl = int(cents/5)

pny = cents -nkl * 5

cents = int(input("Cents: "))

This calculates the quarters in cents

qtr = int(cents/25)

This gets the remaining cents

cents = cents -qtr * 25

This calculates the nickel in remaining cents

nkl = int(cents/5)

This calculates the pennies in remaining cents

pny = cents -nkl * 5

This prints the required output

print(qtr,"quarters,",nkl,"nickels,",pny,"pennies")
