for item in a[:]: if even(item): a.remove(item) # --> a = [1, 3] print(a)常见陷阱 千万别在同一个列表上循环，并在迭代过程中修改它!这和上面的代码是一样的，只是没有在副本上循环。删除一个元素将使所有后续元素向左移动一个位置，因此在下一次迭代中，一个元素将被跳过
例如：a = {1,2,3} a.remove(1) print(a) a.remove(1) print(a)运行结果为：{2, 3} Trac...

To remove duplicates from a Python list while preserving order, create a dictionary from the list and then extract its keys as a new list: list(dict.fromkeys(my_list)).
list.remove(element) 1. 其中,list是列表的名称,element是要移除的元素。 下面的代码示例演示了如何使用remove()方法移除列表中的元素: my_list=[1,2,3,4,5]my_list.remove(3)print(my_list)# 输出 [1, 2, 4, 5] 1. 2. 3. 在上面的例子中,我们移除了列表my_list中的元素3,然后打印出了删除元...
