How to iterate through a list in Python

In Python, you can use loops to iterate through lists. Commonly used loops include for loops and while loops.

1. Use a for loop.

my_list = [1, 2, 3, 4, 5]
for item in my_list:
    print(item)

Output:

1
2
3
4
5

1. Utilizing a while loop:

my_list = [1, 2, 3, 4, 5]
i = 0
while i < len(my_list):
    print(my_list[i])
    i += 1

Output:

1
2
3
4
5

It can be seen that using a for loop is more concise and intuitive, while a while loop is relatively more cumbersome. Therefore, when traversing a list, it is recommended to use a for loop.
