'NoneType' error

[YL1985]

Also, note that print() returns None
so a line like this

dollars = print(float(d.lstrip("$")))

will assign None to name dollars and even if you return dollars you still have a problem.

Check also What is the purpose of the return statement? How is it different from printing?

I see your point.
I tried a different approach and this time I get: "can't multiply sequence by non-int of type 'str' ".
I find it hard to understand how to get an output that is non string nor sequence.

def main():
    dollars = dollars_to_float(input("How much was the meal? ")) # Recall that input returns a str
    percent = percent_to_float(input("What percentage would you like to tip? "))
    tip = dollars * percent
    print(f"Leave ${tip:.2f}")


def dollars_to_float(d):
    return d.lstrip("$")
    int(d)
  

def percent_to_float(p):
    return p.rstrip("%")
    int(p)  


main()
