python百分比數比較大小

python是無法識別百分比的，估計你的百分比是string，所以需要轉成int

# !/usr/bin/python3.4
# -*- coding: utf-8 -*-

# 百分數轉為int
def percent_to_int(string):
    if "%" in string:
        newint = int(string.strip("%")) / 100
        return newint
    else:
        print("你輸入的不是百分比！")


if __name__ == "__main__":

    a = "50%"
    b = "80%"

    # 比較大小
    if percent_to_int(a) > percent_to_int(b):
        print("a > b")
    elif percent_to_int(a) < percent_to_int(b):
        print("a < b")
    elif percent_to_int(a) == percent_to_int(b):
        print("a = b")
    else:
        print("輸入有誤，無法比較")
