Using For Loop

# list of numbers
myList = [5, 10, 14, 25, 30]

# iterating each number in list
for num in myList:
    # checking condition
    if num % 2 == 0:
        print(num, end=" ")

Output:

10 14 30

Using While Loop

# list of numbers
myList = [5, 10, 14, 25, 30]
num = 0

# iterating each number in list
while num < len(myList):

    # checking condition
    if myList[num] % 2 == 0:
        print(myList[num], end=" ")

    # increment num
    num  = 1

Output:

10 14 30

Using Lambda Expressions

# list of numbers
myList = [5, 10, 14, 25, 30]

# lambda expression
even_numbers = list(filter(lambda x: (x % 2 == 0), myList))

print("Even numbers: ", even_numbers)

Output:

Even numbers:  [10, 14, 30]

Using Pass

# list of numbers
myList = [5, 10, 14, 25, 30]

for i in myList:
    if i % 2 != 0:
        pass
    else:
        print(i, end=" ")

Output:

10 14 30

Using Enumerate Function

# list of numbers
myList = [5, 10, 14, 25, 30]

for a, i in enumerate(myList):
    if i % 2 == 0:
        print(i, end=" ")

Output:

10 14 30

Using List Comprehension

# list of numbers
myList = [5, 10, 14, 25, 30]

even_numbers = [num for num in myList if num % 2 == 0]

print("Even numbers: ", even_numbers)

Output:

Even numbers:  [10, 14, 30]

Using Recursion

# list of numbers
myList = [5, 10, 14, 25, 30]

# recursive function
def evenNumbers(list, n=0):
    # base case
    if n == len(list):
        exit()
    if list[n] % 2 == 0:
        print(list[n], end=" ")

    # call function
    evenNumbers(list, n   1)

print("Even numbers:")
evenNumbers(myList)

Output:

Even numbers:
10 14 30
