Python超级超级简易计算器---Lambda匿名函数写法

2417944015

看小甲鱼的书看到了匿名函数，突然发现又可以写一个很简单的计算器

1. print("Python简易计算器--Lambda匿名函数写法...")
   
2. circle=input("请输入一个四则运算式子:")
   
3. if circle.find("+")!=-1:
   
4.     all=lambda infront,behind:infront+behind
   
5.     print(circle.partition("+")[0],"+",circle.partition("+")[2],"=",str(all(float(circle.partition("+")[0]),float(circle.partition("+")[2]))))
   
6. elif circle.find("*")!=-1:
   
7.     all=lambda infront,behind:infront*behind
   
8.     print(circle.partition("*")[0],"*",circle.partition("*")[2],"=",str(all(float(circle.partition("*")[0]),float(circle.partition("*")[2]))))
   
9. elif circle.find("-")!=-1:
   
10.     all=lambda infront,behind:infront-behind
    
11.     print(circle.partition("-")[0],"-",circle.partition("-")[2],"=",str(all(float(circle.partition("-")[0]),float(circle.partition("-")[2]))))
    
12. elif circle.find("/")!=-1:
    
13.     all=lambda infront,behind:infront/behind
    
14.     if circle.partition("/")[2]=="0":
    
15.         print("除数不能为零...程序即将报错停止")
    
16.         assert False
    
17.     print(circle.partition("/")[0],"/",circle.partition("/")[2],"=",str(all(float(circle.partition("/")[0]),float(circle.partition("/")[2]))))
