How can you remove multiple duplicate elements in Python?

One common method for removing multiple identical elements in Python is to use a loop and conditional statement.

# 定义一个列表
my_list = [1, 2, 3, 2, 4, 5, 2, 6, 2]

# 定义一个要删除的元素
to_delete = 2

# 循环遍历列表，删除所有相同的元素
while to_delete in my_list:
    my_list.remove(to_delete)

# 打印删除后的列表
print(my_list)

Running the above code will output [1, 3, 4, 5, 6], which indicates that all instances of the number 2 have been removed.

Important points to note:

1. Using a while loop instead of a for loop is preferred because removing elements can change the length of the list, which may cause errors during traversal.
2. Use the remove() method to delete an element, which will remove the first occurrence of the specified element in the list.
