As you can see, our lists are the same, but the elements aren’t in the same order, so we concluded that our lists are unequal. But what if we wanted to check if our lists have equal elements, no matter their order? If so, we can sort the lists by using the sort() method and...

If you were to try this example in a .py file, you would not see the same behavior, because the file is compiled all at once. This optimization is not limited to integers, it works for other immutable data types like strings (check the "Strings are tricky example") and floats as ...
It will also check that a mapping pattern does not attempt to match the same key more than once. Special attribute __match_args__ The __match_args__ attribute is always looked up on the type object named in the pattern. If present, it must be a list or tuple of strings naming the...
If only globals is given, locals defaults to it. source 参数接受字符串(会作为一个 Python 表达式)或代码对象(可通过 compile() 创建),然后解析并求值,返回求值结果。 eval('{1 + 1}') {2} s = 'for i in range(3):print(i)' code = compile(s,'','exec') eval(code) 0 1 2 eval("_...
