Hey I am trying to make a automatic checkout bot, for now I made it so it can launch multiple undetected chrome instances :

driver = [(uc.Chrome(use_subprocess=True ,options=options1)),(uc.Chrome(use_subprocess=True, options=options2)),(uc.Chrome(use_subprocess=True, options=options3))]

and it runs the code like that :

def Main1():
   i = 0
   login(i)
   checkout(i)
def Main2():
   i = 1
   login(i)
   checkout(i)
def Main3():
   i = 2
   login(i)
   checkout(i)
p1 = threading.Thread(target=Main1, args=())
p1.start()
p2 = threading.Thread(target=Main2, args=())
p2.start()
p3 = threading.Thread(target=Main3, args=())
p3.start()

i stands for driver and account details index. What I wanted to ask is

1. how can I make this code more efficient? copying and pasting over and over doesn't seem like the most efficient thing
2. if I want to run x amount of instances, where all instances have different account details, and choose the amount if instances by inputting the value, how can I do it without manually creating a new function and adding another item to the driver list?

Create a threads list, run them with loop.

def instance(n):
    return [uc.Chrome(use_subprocess=True,options=option) for m in range(0, n)]


def Main(i):
   login(i)
   checkout(i)


threads = [threading.Thread(target=Main, args=(i,)) for i in instance(int(input('num of instances: ')))]
for t in threads:
    t.start()

I have been able to the question using the following code :

buynumber = int(input('Buy number : '))
threadlist = []
driver = []
option = []
for i in range(0, buynumber):
    threadlist.append(i)
threads = [threading.Thread(target=Main, args=(i,)) for i in threadlist]
for i in range(0, buynumber):
    option.append(Options())
    option[i].headless = True
    option[i].add_argument("--disable-gpu")
    option[i].add_argument("--incognito")
    option[i].add_argument("--headless")
for i in range(0, buynumber):
    driver.insert(i, uc.Chrome(use_subprocess=True,options=option[i]))
for t in threads:
    t.start()

for t in threads:
    t.join()
