List Comprehension

 List comprehension offers a shorter syntax when you want to create a new list based on the values of an existing list.

1. expression
2. iteration
3. condition

a=[ele for ele in range(10)] #0,1,2,3,4,5,6,7,8,9

print(a)

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

a=[ele*ele for ele in range(10)]

print(a)

[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

a=[ele*ele for ele in range(10) if ele%2==0]

print(a)

[0, 4, 16, 36, 64]

a=[ele*ele for ele in range(10) if ele%2==1]

print(a)

[1, 9, 25, 49, 81]

========================================

Example:

fruits = ["apple", "banana", "cherry", "kiwi", "mango"]

newlist = []

for x in fruits:

  if "a" in x:

    newlist.append(x)

print(newlist)

Output:

['apple', 'banana', 'mango']

========================================

fruits = ["apple", "banana", "cherry", "kiwi", "mango"]
newlist = [x for x in fruits if "a" in x]
print(newlist)
