遇到一些关于python的列表的麻烦

Question

def main():
    num_list = []
    n = input('Your favorite number: ')

    again = 'g'

    while again == 'g':
        value = float(input('Enter a number: '))
        if value > n:
            num_list.append(value)
        print ('Would you like to enter another number?: ')
        again = input('y=yes, n=no')
main()

Here's my code. The > isn't working, what do i do?

Answer 1

I see two problems with your code,

1. As comments says, your comparing a float type to a str . Note that it is possible in Python 2 to compare mixed types for nonsensical answers, not in Python 3.

2. You're comparing your again variable against 'g' only. which is clearly not what you want. Try this code :

    def main(): num_list = [] n = input('Your favorite number: ') again = 'g' while again in {'g','y'} : value = float(input('Enter a number: ')) if value > float(n): num_list.append(value) print ('Would you like to enter another number?: ') again = input('y=yes, n=no') main()
