Question

Please attach the output screenshots, narrative descriptions, or paste the Python codes when requested.

Task 2

Please define a function that extracts the even numbers in a given list. For example, given a list x = [2,3,5,6,7], the function will return a sublist [2,6] because 2 and 6 are even numbers in the list x.

The input of this function should be a list, and the output of the function should be a list as well (the sublist).

You can try the inline for loop with conditions to make the solution super simple.

Task 3

Use inline for loop to extract the common elements in two lists. For example, if x = [1,2,3], and y = [2,3,4], the result should be [2,3].

Hint: to check if a value exists in a list, you can use the “in” command. For example: we define two variables

a = 2 in [1,2,3]

b = 4 in [1,2,3].

After executing the codes, a will be a “True”, and b will be a “False”.

Answer 1

Answer 1:

def evenList(myList):

res=[]

#iterating throught list

for x in myList:

#checking if even than adding to new list

if x%2==0:

res.append(x)

#returning new list

return res

print(evenList([2,3,5,6,7]))

Answer 2:

def commonList(list1,list2):

res=[]

#iterating throught list

for x in list1:

#checking if element exist in list2 than adding to new list

if x in list2:

res.append(x)

#returning new list

return res

print(commonList([2,3,5,6,7],[2,3,4,7,9]))
