Adding two values from FOR loops

Hi there Gregory, this is how i would go about doing the challenge; firstly, you need to create a new list to store your tuples in:

new_list = []

Next, its time to create the for loop. I would loop through list_1 and that at the beginning of the tuple, next i would use list_2[i-1] to get the corresponding value from list_2 since indexes start at 0 and I will be using i as my loop counter:

for i in list_1:
    new_list.append((i, list_2[i-1]))

If you have any further questions, please leave a comment :)

Thanks,

Haider

Hi Gregory, Haider Ali did a good explanation about a way to solve you problem!

However, there is a easier and easier-to-understand way. The enumerate and zip functions can be very handy. Examples:

my_list = ["a", "b", "c"]

# Enumerate
for x, y in enumerate(my_list):
    print("{}: {}".format(x, y))

# This will print:

#   0: a
#   1: b
#   2: c

# Zip
my_second_list = ["d", "e", "f"]
for x, y in zip(my_list, my_second_list):
    print("{}: {}".format(x, y))

# This will print:

# a: d
# b: e
# c: f

You can solve your task by doing this:

list_1 = [1, 2, 3, 4, 5]
list_2 = list("abcde")
result_list = []

index = 0
for x, y in zip(list_1, list_2):
    result_list.append((x, y))
    index += 1

print(result_list)

Hope that helps! ~xela888
