Answer:
def corresponding_of_lists(lst1, lst2):
c = ""
corresponding_list = []
if (lst1 is None) or (lst2 is None):
return None
else:
for i in lst1:
for j in lst2:
c = "(" + str(i) + "," + str(j) + ")"
corresponding_list.append(c)
return corresponding_list
Explanation:
- Create a function called corresponding_of_lists that takes two lists as parameter
- Initialize an empty list to hold the corresponding values
- Check if any of the lists are null, if they are return None
- Otherwise, get the corresponding elements and put them into the corresponding_list
Return the corresponding_list
