Python example of a method that simply deletes the same element in a list

This article example shows how Python can simply delete the same elements from a list. To share for your reference, specific as follows:

Remove duplicate elements from the list, very simple, directly on the code:

a = [11, 21, 3, 4, 3, 2, 5]
b = list(set(a))
print(a)
print(b)

Operation results:

E:\Program\Python>d.py
[11, 21, 3, 4, 3, 2, 5]
[2, 3, 4, 5, 11, 21]

You see, there are no repeating elements. But, at the same time, the elements in the result are sorted from smallest to largest!

PS: Here are a few more repetition tools you can use:
