Python超级超级简易计算器---闭包方法

2417944015

还是要感谢Twilight6这位资深程序员，否则我还理解不了闭包的原理

print("Python简易计算器--闭包+Partition方式")
circle=input("请输入一个四则运算式(例如:8*400):")
if circle.partition("+")[0]!=circle:
    def one(num1):
        def two(num2):
            return num1+num2
        return two
    temp=one(float(circle.partition("+")[0]))
    print(circle.partition("+")[0],"+",circle.partition("+")[2],"=",str(temp(float(circle.partition("+")[2]))))
if circle.partition("-")[0]!=circle:
    def one(num1):
        def two(num2):
            return num1-num2
        return two
    temp=one(float(circle.partition("-")[0]))
    print(circle.partition("-")[0],"-",circle.partition("-")[2],"=",str(temp(float(circle.partition("-")[2]))))
if circle.partition("*")[0]!=circle:
    def one(num1):
        def two(num2):
            return num1*num2
        return two
    temp=one(float(circle.partition("*")[0]))
    print(circle.partition("*")[0],"*",circle.partition("*")[2],"=",str(temp(float(circle.partition("*")[2]))))
if circle.partition("/")[0]!=circle:
    def one(num1):
        def two(num2):
            return num1/num2
        return two
    temp=one(float(circle.partition("/")[0]))
    if circle.partition("/")[2]=="0":
        print("除数不能为零...程序即将报错停止")
        assert False
    print(circle.partition("/")[0],"/",circle.partition("/")[2],"=",str(temp(float(circle.partition("/")[2]))))
