Python List Loops, Print Satellite Names according to Number Enetered after Comma

UserInput: (“LANDSAT8,5,MODIS,3,SENTINAL2,6”).
User entered three satellites name and instruct the program that how many images of that
particular satellite should be downloaded. In this example, there are three pairs;

1. LANDSAT8,5
2. MODIS,3
3. SENTINAL2,6

Preferred Output should be like:

Program Output:
LANDSAT8 image 1 downloaded
LANDSAT8 image 2 downloaded
LANDSAT8 image 3 downloaded
LANDSAT8 image 4 downloaded
LANDSAT8 image 5 downloaded
MODIS image 1 downloaded
MODIS image 2 downloaded
MODIS image 3 downloaded
SENTINAL2 image 1 downloaded
SENTINAL2 image 2 downloaded
SENTINAL2 image 3 downloaded
SENTINAL2 image 4 downloaded
SENTINAL2 image 5 downloaded
SENTINAL2 image 6 downloaded

>Solution :

I think this may be what you’re trying to do:

user_input = "LANDSAT8,5,MODIS,3,SENTINAL2,6"

tokens = user_input.split(',')

for s, d in zip(tokens[::2], map(int, tokens[1::2])):
    for i in range(d):
        print(f'{s} image {i+1} downloaded')

Output:

LANDSAT8 image 1 downloaded
LANDSAT8 image 2 downloaded
LANDSAT8 image 3 downloaded
LANDSAT8 image 4 downloaded
LANDSAT8 image 5 downloaded
MODIS image 1 downloaded
MODIS image 2 downloaded
MODIS image 3 downloaded
SENTINAL2 image 1 downloaded
SENTINAL2 image 2 downloaded
SENTINAL2 image 3 downloaded
SENTINAL2 image 4 downloaded
SENTINAL2 image 5 downloaded
SENTINAL2 image 6 downloaded
