The following example shows how to use both local and global variables in the same Python program
Example
Start IDLE.
Navigate to the File menu and click New Window.
Type the following:
y = "global"
def foo():
global y
x = "local"
y = y * 2
print(y)
print(x)
foo()
Discussion
The output of the program will be:
global global
local
Discussion
We declared y as a global variable and x as a local variable in the foo(). The * operator issued to modify the global variable y and finally, we printed both y and x.
Local and Global Variables with the same name
Start IDLE.
Navigate to the File menu and click New Window.
Type the following:
y=6
def foo():
y=11
print(“Local variable y-“, y)
foo()
print("Global variable y-", y)
