Explanation: Here, the function checks whether a number is even or odd by using the modulus operator. Here,15 and 10 are passed as arguments to check whether they are odd. There are four types of function argum
To compare a string with an enum, extend from thestrclass when declaring your enumeration class, e.g.class Color(str, Enum):. You will then be able to compare a string to an enum member using the equality operator==. How to compare a string with an Enum in Python | bobbyhadz class ...
When you use the * operator to unpack a list and pass arguments to a function, it’s exactly as though you’re passing every single argument alone. This means that you can use multiple unpacking operators to get values from several lists and pass them all to a single function. To test ...
The functionaveragein the example shows you how to do this with your function argument*args. The asterisk operator creates a sequence of values from an arbitrary number of positional arguments. It’s really this: it creates a new variable with the nameargsthat is visible within the function. ...

在Python 3 中,有一个新用法,称为bare asterisk/star。即,在函数定义中,参数之间,有一个光秃秃的 * 符号。这种用法的含义是 bare star 的后面,只能接受关键字参数。更多解释参见PEP 3102 -- Keyword-Only Arguments。具体示例如下: defcompare1(x, y, *, key=None):print('x:', x)print('y:', y)...
The standard operation of division, which is performed by the / operator, generally returns a floating-point result. The returned result (quotient) can be an integer only if the first operand (dividend) is evenly divisible by the second operand (divider), or, in other words, it is divided...

输出:<function bar at 0x006798A0> 详解:foo(bar)把函数bar直接当成实参传给形参foo(n),实际做的操作就是把bar赋值给n了,函数当成变量赋值了n=bar <2>返回值可以是函数名 deffoo(n):print(n)defbar(name):print('my name is %s'%name)
