How python uses list comprehension instead of the original for loop

Editor to share with you how python uses list comprehension instead of the original for cycle. I hope you will get something after reading this article. Let's discuss it together.

Use list comprehension instead of the original for loop

Suppose we want to create a list with a specific value, in this case a list of all squares between 0 and 9. The tedious approach is to create an empty list, then use a for loop to calculate it, and append it to the list:

Squares = [] for i in range (10): squares.append (iTuni)

An easier way is list comprehension. Here we only need one line to do the same thing:

# better: squares = [iTuni for i in range (10)]

List comprehension is very powerful, even including if statements. Note that the use of list comprehension is a little controversial. It should not be overused, especially if it harms the readability of the code. But personally, I think this grammar is clear and concise.
