不同于C语言和SHELL,python中没有switch case语句,关于为什么没有,官方的解释是这样的
使用Python模拟实现的方法:
def switch_if(fun, x, y):
...if fun == 'add':
return x + y
elif fun == 'sub':
return x - y
elif fun == 'mul...,1,2):",switch_if('add',1,2))
print("switch_if('sub',1,2):",switch_if('sub',1,2))
print("switch_if('mul...',1,2):",switch_if('mul',1,2))
print("switch_if('div',1,2):",switch_if('div',1,2))
print("switch_dict...',1,2): 3
switch_dict('sub',1,2): -1
switch_dict('mul',1,2): 2
switch_dict('div',1,2): 0.5
