Python import vs direct execution

#conf.py

def init():
    global mylist   
    mylist=[]


#change.py

import conf

def change():
    if __name__ == "__main__":
        print('Direct')
        conf.mylist.append('Directly executed')
        print(conf.mylist)
    else:
        conf.mylist.append('It was imported') 


#exec.py

import conf
import change

conf.init()  
change.change()

print (conf.mylist)

When running exec.py the result is what I expected, but when running change.py directly I didn't get any output (no Direct , no conf.mylist)

Yes, that's the normal behavior. You need to call the change function for this code to execute.

You can add the following to the end of change.py

if __name__=="__main__":
    change()

This is because change is never invoked. Invoke it at the end of the file with change()
