How to call a function within a class from another script?-CodePudding

Class Script:

class Test2:

def __init__(self):
    self.a=10
        
    self.sq()
    
def sq(self):
    print(self.a*2)
    
def call_later(self):
    print("Called Later")

Calling Function from another script:

from test2 import *
import time

Test2()

time.sleep(30)

#I want to call this function without creating the object again
Test2.call_later()

How do I call a class function later on after the object has been created?

CodePudding user response：

You need to create an object of the class so

from test2 import Test2

Test2().sq()

CodePudding user response：

You need to put both file in the same directory then create an instance of your class Test2 like this:

from test2 import Test2()
test2 = Test2()
test2.sq()

I hope it helped you

CodePudding user response：

You are trying to call an instance method on a class. So either you instantiate the class (like shown in the above answer) or you make the method static and the member variable a class variable:

class Test2:
    a = 10

    @staticmethod
    def sq():
        print(Test2.a * 2)

and then you call the static method:

Test2.sq()
