Have a question, I'm some new in threading, I made this code....

import threading
from colorama import *
import random
import os

listax = [Fore.GREEN,Fore.YELLOW,Fore.RED]
print(random.choice(listax))

def hola():
    import requests
    a = requests.get('https://google.com')
    print(a.status_code)

if __name__ == "__main__":
    t1 = threading.Thread(target=hola)
    t2 = threading.Thread(target=hola)
    t3 = threading.Thread(target=hola)

    t1.start()
    t2.start()
    t3.start()

    t1.join()
    t2.join()
    t3.join()

And output shows 3 times if I execute 3 times the code, but my question is, for example, if I have big code and all start in:

def main():
    code...

How I can add multiple threading for fast work, I see I can add 1 thread, if I add 3 threads the output shows 3 times, but how I can do it for example for add 10 threads to the same task without the output repeating 10 times for this execute fast as possible using the resourses of the system?

CodePudding user response：

You can simply use a for loop.

number_of_threads is the number of how many thread u want to run

for _ in range(number_of_threads):

    t = threading.Thread(target=hola)
    t.join()
    t.start()

CodePudding user response：

i tried to use the loop of the code you give me

# Python program to illustrate the concept
# of threading
# importing the threading module
import threading
from colorama import *
import random
import os

listax = [Fore.GREEN,Fore.YELLOW,Fore.RED]
print(random.choice(listax))

"""
def print_cube(num):
    function to print cube of given num
    print("Cube: {}".format(num * num * num))
"""  
def print_square():
    num = 2
    """
    function to print square of given num
    """
    print("Square: {}".format(num * num))
def hola():
    import requests
    a = requests.get('https://google.com')
    print(a.status_code)
  
if __name__ == "__main__":
    for j in range(10):
        t1 = threading.Thread(target=hola)
        t1.start()
        t1.join()

but when i run the code the code run 1 print per time, in my case give me 200 1 sec later again 200 and 200 again (x 10 times because i added 10 thread)

but i want know how i can do for this execute as fast possible without show me the 10 output, just i want the code do 1 print but as fast possible with 10 thread for example
