+List comprehension is generally more compact and faster than normal functions and loops for creating list.
+However, we should avoid writing very long list comprehensions in one line to ensure that code is user-friendly.
+Remember, every list comprehension can be rewritten in for loop, but every for loop can’t be rewritten in the form of list comprehension.
