"List comprehension is the concise & elegant way to create the list by using for loop".

List Comprehension in python

Let's see some example-

# Create a list having square of a number from 0 to 5

l=[var**2 for var in range(0,6)]
print(l)

>> [0,1,4,9,16,25]

# create a list having even numbers from 0 to 10

l=[var for var in range(0,11) if var%2==0 ]
print(l)

>>[0, 2, 4, 6, 8, 10]

# create list of name starts with the letter 'p' from the list given list 
l=['Tamta','Pandita','Alok','Sauru','Pakiya','Gaurav','Piku','Dheru','Pasha','Akshay','Shishir','Dharmu','Piyush']
print([var for var in l if var[0]=='P'])

>> ['Pandita', 'Piku', 'Pasha', 'Piyush']

# Garb the letter from the word 'hello and convert into uppercase

l=[var.upper() for var in 'hello']

print(l)

>> ['H','E','L','L','O']
