why does my class is executing on its own?

so i'm working on a code but I encounter a error and idk why but I will give the details of the code

#sc.py
import getpass
import time
import subprocess
import sys
#time
t = time.localtime()
current_time = time.strftime("%H:%M:%S", t)
#class
class password_log:
	def __init__(self,**value):
		self.passwordattemptslog = value['pwdalog']
		self.maincode = value["maincode"]
		self.var_input = value["var_input"]
		self.inputpassword = value["password"]
		self.logs = value["logs"]
		self.f_obj = value["log_file"]
		self.file = open(self.f_obj,'r+')
		self.wrongpassword_attempts = 0
	def checker(self):#checker
		if self.logs == True:
			if  self.var_input == self.inputpassword:
				self.maincode
						#logs
				self.correctpassword()
			elif self.var_input != self.inputpassword:
				print("wrong password")
				self.wrongpassword()
				self.wrongpassword_attempts += 1
			elif self.wrongpassword_attempts > self.passwordattemptslog:
				self.limitpassword()
			else:
				print("error")


		elif self.logs == False:
			if self.var_input == self.inputpassword:
				self.maincode
			elif self.var_input != self.inputpassword:
				print("wrong password") 
			else:
				print("error")
		else:
			print("error")

	#logs
	def correctpassword(self):
		self.file.write("\ncorrect password" +" time:" + current_time + "\n" )

	def wrongpassword(self):
		self.file.write("\nwrong password" +" time:" + current_time + "\n" )
		self.file.write("\n the wrong password input:" + self.var_input)
	def limitpassword(self):
		self.file.write(f"\n {self.passwordattemptslog} wrong attempts of password time:" + current_time + "\n" )

#main.py
from sc import password_log
import getpass


class main:
	@staticmethod		
	def runtest():
		print("runtest")





log_input = getpass.getpass(prompt = "password:")

paswlog = password_log(password = "2008", logs = True, var_input = log_input,maincode = main.runtest() , log_file = "filetext.txt", pwdalog = 10)

paswlog.checker()

output:
runtest
password:

The runtest() has already been executed, but it should only be run if the password is correct.

im just new at python and experimenting some stuff so yeah i need a little help on this one

i expect that the runtest() should only be run if the password is correct

Instead of passing the runtest function as an argument, you are executing the function and passing its return value. Which in this case in None. This is assuming you want to run it in password_log.checker and use its return value.

log_input,maincode = main.runtest() #  Wrong
log_input,maincode = main.runtest   #  Right 

My first instinct is in main.py, on the line maincode = main.runtest(), it should be maincode = main.runtest. Otherwise you would immediately call the function and set maincode to its return value. This early call of the function probably explains why your program executes immediately bypassing the password check

Then, in sc.py in checker, wherever you want to call maincode, it should be maincode(), otherwise you would just name the function without actually calling it.

I cannot test this so those are just my guesses. Let me know if they help.
