In the example usage section, we call the "get_numeric_input()" function twice to obtain two numerical inputs from the user. The inputs are stored in n1 and n2 respectively. We then perform a simple multiplication on the numbers and print the result. Output: Input the first number: a ...

可以使用“for”命令迭代列表和字节组:a5 = ['Aa', 'Bb', 'Cc'] for v in a5: print v这会依次将 v 设置为列表 a5 的每个元素。可能会定义如下所示的函数:def myfunc(p1, p2): "Function documentation: add two numbers" print p1, p2 return p1 + p2...
查询:字典可以直接索引键,也可以使用 get(key, default) 函数来进行索引;集合并不支持索引操作,因为集合本质上是一个哈希表,和列表不一样。要判断一个元素在不在字典或集合内,可以用 value in dict/set 来判断。 更新:字典增加、更新时指定键和对应的值对即可,删除可用pop() 操作;集合增加可用add()函数,删除...

Use stringisdigit()method to check user input is number or string Note: Theisdigit()function will work only for positive integer numbers. i.e., if you pass any float number, it will not work. So, It is better to use the first approach. ...
拥有ChainMap对象后,您可以使用字典样式的键查找来检索现有键,或者您可以使用.get(): >>> from collections import ChainMap >>> numbers = {"one": 1, "two": 2} >>> letters = {"a": "A", "b": "B"} >>> alpha_num = ChainMap(numbers, letters) >>> alpha_num["two"] 2 >>> alpha...
