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

1. print("Python简易计算器--闭包+Partition方式")
   
2. circle=input("请输入一个四则运算式(例如:8*400):")
   
3. if circle.partition("+")[0]!=circle:
   
4.     def one(num1):
   
5.         def two(num2):
   
6.             return num1+num2
   
7.         return two
   
8.     temp=one(float(circle.partition("+")[0]))
   
9.     print(circle.partition("+")[0],"+",circle.partition("+")[2],"=",str(temp(float(circle.partition("+")[2]))))
   
10. if circle.partition("-")[0]!=circle:
    
11.     def one(num1):
    
12.         def two(num2):
    
13.             return num1-num2
    
14.         return two
    
15.     temp=one(float(circle.partition("-")[0]))
    
16.     print(circle.partition("-")[0],"-",circle.partition("-")[2],"=",str(temp(float(circle.partition("-")[2]))))
    
17. if circle.partition("*")[0]!=circle:
    
18.     def one(num1):
    
19.         def two(num2):
    
20.             return num1*num2
    
21.         return two
    
22.     temp=one(float(circle.partition("*")[0]))
    
23.     print(circle.partition("*")[0],"*",circle.partition("*")[2],"=",str(temp(float(circle.partition("*")[2]))))
    
24. if circle.partition("/")[0]!=circle:
    
25.     def one(num1):
    
26.         def two(num2):
    
27.             return num1/num2
    
28.         return two
    
29.     temp=one(float(circle.partition("/")[0]))
    
30.     if circle.partition("/")[2]=="0":
    
31.         print("除数不能为零...程序即将报错停止")
    
32.         assert False
    
33.     print(circle.partition("/")[0],"/",circle.partition("/")[2],"=",str(temp(float(circle.partition("/")[2]))))
