not abel to run selenium automation one by one in loop

[DevilzKingz]

HELLO, i just learned python and this is my first project.
everything is working fine except looping part. if amount is 10 and i have 2 automation site functions. so as loop starts, loop count 1 and site function should be 1 and as as loop count 2 so site function 2 should start but its not working like that. as the loop starts site 1 function repeating 10 times then it goes to site 2 function, i dont want like this. i want to make it, 1 count = site 1 function, count 2 = site 2 function should work. PLEASE HELP. THANK YOU.
