Change my_list[1] to my_list[9] by adding 8 when reaching an if statement

August 1, 2022

I need to be able to change "X" of the my_list[X] value once reaching an if statement by adding a number to the value. Here’s a basic example of my code:

with open("*/file.txt") as f:
    data = f.read()
my_list = data.splitlines()

print(my_list[1])

Result:

Line 1 of my_list

What I need:

if sky = blue
    my_list[+8]
print(my_list[9]) #the result of my_list[1] +8

Resulting in

Line 9 of my_list

I have a total of 8 my_list[X] values, and I need to be able to add 8 to the [X] number to automatically select the next set of lines once the if statement is reached (kinda repeated myself there).

>Solution :

I think it would do the trick!

i=1
with open("*/file.txt") as f:
    data = f.read()
my_list = data.splitlines()

while True:
    print(my_list[i])
    # do stuff 

    if "sky" == "blue":
         i+=8
     
    # MUST specify exit condition

But do not forget to specify the exit condition and account for "IndexError: list index out of range"!
