Python | Filter even values from a list

Given a list of numbers, the task is to make a new list containing only even values.

Examples:

Input: list = [1, 2, 3, 4, 5]
Output: [2, 4]

Input: list = [12, 14, 95, 3]
Output: [12, 14]

Method #1 : Using For loop
Iterate each element in the list using for loop and check if num % 2 == 0. If the condition satisfies, then append it in output list.

# Python code to filter even values from a list

# Initialisation of list
lis = [1,2,3,4,5]

# Output list initialisation
out = []

for num in lis:

    # checking condition
    if num % 2 == 0:
        out.append(num)


# printing output
print(out)

Output:

[2, 4]

Method #2 : Using While loop

# Python code to filter even values from a list

# Initialisation of list
lis = [1,2,3,4,5]
num = 0

# Output list initialisation
out = []
while(num < len(lis)):

    # checking condition
    if lis[num] % 2 == 0:
        out.append(lis[num])
    # increment num
    num += 1


# printing output
print(out)

Output:

[2, 4]

Method #3 : Using list Comprehension

# Python code to filter even values from a list

# Initialisation of list
lis = [1,2,3,4,5]

lis2 = [i for i in lis if i%2 == 0]

# Printing output
print(lis2)

Output:

[2, 4]

Method #4 : Using filter()

# Python code to filter even values from a list

# Initialisation of list
lis1 = [1,2,3,4,5]

is_even = lambda x: x % 2 == 0

# using filter
lis2 = list(filter(is_even, lis1))

# Printing output
print(lis2)

Output:

[2, 4]
