scope - Global variables across multiple files in python -


i have modules.py file :

global dns_server_ip def setvnetglobalparameters():     dns_server_ip = '192.168.3.120'

and i’m importing file in abc.py file

from modules import * setvnetglobalparameters() print(dns_server_ip)

but ‘dns_server_ip’ still not accessible.

i want set global parameters through function only. appreciated! thanks..

as per question understand beginner python.

while importing modules have use module name , don't need include extension or suffix(py) , in code miss starting single quote .

here modified code: modules.py

dns_server_ip = '' def setvnetglobalparameters():     global dns_server_ip     dns_server_ip = '192.168.3.120′

here abc.py

import modules  modules.setvnetglobalparameters() print modules.dns_server_ip

here through global keyword telling python interpreter change or point out global variable instead of local variable , variable either global or local if variable both (local , global) python unboundlocalerror exception , if did not put global keyword 

global dns_server_ip

the dns_server_ip created new local variable . keyword global intended in functions only

you can check global keyword,python modules

Why does Ruby on Rails generate add a blank line to the end of a file? -
