1) Write a function which accepts a list and returns list of squres.
print(get_squres([1, 2, 3, 4, 5, 6, 7]))
output : [1, 4, 9, 16, 25, 36, 49]

Solution:

def get_squres(list1):
list3 = []
for x in range(len(list1)):
list3.append(list1[x] + list2[x])
return list3
print(get_squres([1,2,3,4,5])

2) Write a function to Join two list as below:
input:
list1 = ["Hello ", "take "]
list2 = ["Dear", "Sir"]
output : ['Hello Dear', 'Hello Sir', 'take Dear', 'take Sir']

Solution:

list1 = ["Hello ", "take "]
list2 = ["Dear", "Sir", "Madam"]
list3 = []
for x in list1:
for y in list2:
list3.append(x + y)
print(list3)

3) Given a two Python list. Write a program to iterate both lists simultaneously and display items as shown in output.
input:
list1 = [10, 20, 30, 40]
list2 = [100, 200, 300, 400]
output :
10 100
20 200
30 300
40 400

Solution:

for x in range(len(list1)):
print(list1[x])
list1 = [10,20,30,40]
list2 = [100,200,300,400]
for x in range(len(list1)):
print(str(list1[x]) + " " + str(list2[x]))

4) Write a function to remove empty strings from the list of strings
