How to access a variable in one python function in another function (python)

Question

import requests

class location:
def __init__(self,city):
self.city=city

def ct(self):
global req_read
req=requests.get(self.city)
req_read=req.text
return req_read

def ct_2(self):
global req_read
return req_read

a=location("https://www.metaweather.com/api/location/search/?query=paris")
print(a.ct_2())

Answer 1

I believe you can do:

def __init__(self, city):
self.city = city
self.req_read = ''

...and refer to your req_read variable using self.req_read everywhere else in your class. This means you don't need your global req_read statements.

Hope this is what you wanted.

Answer 2

Pass it as an argument to the function.

For a free (not in a class) function for example:

def f(x, y):
# Do stuff with x and y

call it like this:

f(value1, value2)
# value1 and value2 being
# the values you want to use

For class methods:

class C:
def f(self, x, y):
# Do stuff with x and y

Make an instance, then call the method like this:

c = C()
c.f(value1, value2)
