Python Python Loop Through List Items
List Comprehension
List comprehension offers a shorter syntax when you want to create a new list based on the values of an existing list.
Example: You want to create a list of all the fruits that has the letter "a" in the name.
Without list comprehension you will have to write a for statement
with a conditional test inside:
Example
fruits = ["apple", "banana", "cherry", "kiwi", "mango"]
newlist = []
for x in fruits:
if "a" in x:
newlist.append(x)
print(newlist)

With list comprehension you can do all that with only one line of code:
Example
fruits = ["apple", "banana", "cherry", "kiwi", "mango"]
newlist = [x
for x in fruits if "a" in x]
print(newlist)

The list comprehension is wrapped around square backets, contains one or more for statements, zero or more if statements, and returns a new list.
