Global static variables in Python

def Input():
    c = raw_input ('Enter data1,data开发者_运维技巧2: ')
    data = c.split(',')
    return data

I need to use list data in other functions, but I don't want to enter raw_input everytime. How I can make data like a global static in c++ and put it everywhere where it needed?


Add the global keyword to your function:

def Input():
    global data
    c = raw_input ('Enter data1,data2: ')
    data = c.split(',')
    return data

The global data statement is a declaration that makes data a global variable. After calling Input() you will be able to refer to data in other functions.


using global variables is usually considered bad practice. It's better to use proper object orientation and wrap 'data' in a proper class / object, e.g.

class Questionaire(object):
    def __init__(self):
        self.data = ''

    def input(self):
        c = raw_input('Enter data1, data2:')
        self.data = c.split(',')

    def results(self):
        print "You entered", self.data

q = Questionaire()
q.input()
q.results()
0
