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


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

it fixes the issue I wrote a couple of functions to calculate the NPS and Margin of error of a sample responses. , You have to declare the variable to be global, then use it. Like so:
code :
def add_to_outside():
    global outside #say that it is global
    outside = 1 #now create it!

def see_it():
    global outside #say that it is global
    print(outside)

##As shown:
add_to_outside()
see_it()
#output: 1
global var1, var2, var3 #etc.

To fix this issue When asking a question, it is usually good form to include the question itself, as well as an indication of how things behave unexpectedly, and what was expected.
The main thing to remember about global is that it does not create variables. It only informs the compiler that those names belong to an outside scope (module level rather than function). Thus a combination like:
code :
global sayac
sayac=sayac +1
def baslat_btn(self):
    sayac=0
    #...
    sayi=random.randint(0,100)
    #...
    return sayi
    return sayac

it should still fix some issue As i have set search term to global for the first function - shouldnt the second function be able to access it - if not how would i get this to work? , In your setupsearch use
code :
        Button(gui2,
               text="Search",
               command = lambda: search(thesearchterm)).grid(row = 2)
def search(searchterm):
    ...

this will help The answer by robert is probably the easiest way to do what your want. Here is another:
code :
class class1():
    a,b = somevalues, somevalues
    @staticmethod
    def func1():
        do something

func2(class1.a, class1.b)
class1.func1()
def func1():
    func1.a = somevalue
class example:
    a = somevalue
class1.a
class1.func1()
func1 = class1.func1
func1()
class class1:
    def __init__(self, a, b):
        self.a, self.b = a, b
    @staticmethod
    def func1():
        dosomething

obj1 = class1(somevalue1A, somevalue1B)
obj2 = class1(somevalue2A, somevalue2B)
func2(obj1.a, obj1.b)
func2(obj2.a, obj2.b)
obj1.func1()
obj2.func1()
class1.func1()

like below fixes the issue In Python, the global keyword is only needed when you are writing to a variable. Inside test_variable() you have defined a NEW variable named index, though it seems your intent was to write to the variable defined outside that scope.
When you read from a variable name, Python starts in the innermost scope and if the name isn't found, continues looking in the containing scopes.
In Python, make a variable act like a function, call a function without parentheses, alias a function as a variable, etc

Does that help I am working with slightly modifying someone else's code for my needs and want to replace what is currently a fixed variable with a function. But adding a () to each time the variable is referenced later to get the value is simply not feasible in this situation, or would not be worth the amount of work required. I need a way to define a variable as a function such that while it is referenced as a variable in all further code, it actually checks what the value should be each time it is queried as if I had added parentheses to each reference. I do not care how this is achieved, but it should not require any changes to the code that references the former-variable. , You could maybe get there with a class with a property.
code :
import random as r

class AlwaysRandom:
  @property
  def random(self):
    return r.random()
random = AlwaysRandom()
>>> random.random
0.1993064343052221
>>> random.random
0.9121594527461093
>>> [random.random for _ in range(5)]
[0.0800719907184344, 0.14744257667766358, 0.5809572562744559, 0.337413501046831, 0.52033363367589]
