When it comes to data structures in Python, lists are a crucial component. They are a type of sequence, which means they can hold multiple elements, such as strings, integers, and other data types. One of the most useful features of lists is that they are mutable, meaning you can add ...
在这种情况下,可以创建自定义异常类,并在适当的地方引发它们。 classCustomError(Exception):passclassMyList:def__init__(self):self.items = []defadd(self, item):ifisinstance(item,int): self.items.append(item)else:raiseCustomError("Only integers can be added to MyList") my_list = MyList()tr...

To create a list, you simply put a number of items or expressions in a square bracket separated by commas. [expression1, expression2,...,expresionN] >>> l = [4,3,5,9+3,False] >>> l [4, 3, 5, 12, False] Also, Python has a built-in object calledlist() that can be used...
