Question

I am trying to change a variable further down the program. I have a global variable declared at the start of the program and I want to change the variable in different functions down the program. I can do this by declaring the variable inside the function again but I would like to know is there a better way of doing this. Some test code is below to explain what I mean.

ID = 'No'
project = ("Yep"+ID) # ID added with 'No' value which I later want to change

def pro():

    ID = "YES"
    print ID

def pro1(ID):

    # I could declare project again to get this to work, but I would like to avoid this
    print project # I want this to print with the new ID number.

if __name__ == '__main__':
    pro()
    pro1(ID)

Has anyone any ideas, thanks

I have tried the global variable but when I do this the project variable still prints out YepNo instead of YepYES. I want the new variable from the function proto change the variable in the project variable.

To update global variables you could use

global ID
ID="Yes"

before assigning variable to ID = “YES”

But changing ID will be no effect on project variable, project = ("Yep"+ID), because project is already a string

you need to make a function like

def getprojectname(ID):
    return project+ID

The whole program may be like this
