without list comprehension
fruits = ['Apple','Orange','Grapes','Apricot','Avocado']
a_fruits = []
for fruit in fruits:
if 'A' in fruit:
a_fruits.append(fruit)
print(a_fruits)
list comprehension
a_fruits = [fruit for fruit in fruits if 'A' in fruit ]
print(a_fruits)
copy list comprehension
a_fruits_copy = [fruit for fruit in fruits ]

Example 2: without list comprehension
even_number = [1,2,3,4,5,6,7,8,9,10]
for even in even_number:
if even % 2 == 0:
print(even)
with list comprehension
even_num = [even for even in even_number if even % 2 == 0]
print(even_num)
