Python中没有Switch语句,但可以使用字典(Dictionary)或if-elif-else语句实现类似功能。以下是使用这两种方法的示例代码。方法一:使用字典(Dictionary) # 定义一个字典,将各个条件映射到相应的函数或值上 switch_dict = { 'case1': lambda: print('这是case1'), 'case2': lambda: print('这是case2'), 'def...
elif self.value in args: # changed for v1.5, see below self.fall = True return True else: return False # The following example is pretty much the exact use-case of a dictionary, # but is included for its simplicity. Note that you can include statements # in each suite. v = 'ten'...
switch (key) { case 'a': /* do_a */ break; case 'b': /* do_b */ break; case 'c': /* do_c */ break; } 在Python中一般表示成 1 2 3 4 5 6 if key == 'a': # do_a elif key == 'b': # do_b elif key == 'c': # do_c if-else足够简单,也足够实用,它也能模...
python 1、构建字典。前面key的数字代表用户输入的功能序号。value代表相应的功能函数。 很酷的站长 2022/11/24 5990 python-fire的使用 python 本文完全转载自:https://github.com/google/python-fire/blob/master/docs/guide.md#version-3-firefireobject py3study 2020/01/08 9510 分布式并行架构Ray介绍 node....
We can use dictionaries as a switch case in Python. When a user gives input to search for anything, the input matches the dictionary key, and if found, it prints the values of that key. Syntax dict = {Keys : Values} dict = {Keys: Values}: Here, keys can be anything like string,...
Explanation:Dictionaryin Python is an unordered collection of key and value pairs. In the below code snippet, the switcher is a dictionary variable that is holding key: value pairs similar to switch-like cases. Using the get() method, we can access the item of the dictionary by passing the...
Another way is to go for the dictionary switcher method. In this, we can create a function with a dictionary called switcher. Moreover, we can construct the dictionary using the key and value pairs just like a case statement in the conventional switch method. The explanation of the same is...
Python中switch-case实现(转) Python不像C/C++,Java等有switch-case的语法。不过其这个功能,比如用Dictionary以及lambda匿名函数特性来替代实现。 比如PHP中的如下代码: switch($value) {...
