module variables python code example
Example 1: global variable not working python
trying to assign a global variable in a function will result in the function creating a new variable
with that name even if theres a global one. ensure to declare a as global in the function before any
assignment.
a = 7
def setA(value):
global a
a = value
Example 2: Traceback (most recent call last): File "main.py", line 3, in y = eval((x**3+2*x)/(x**4+3(x**2)+1)) TypeError: 'int' object is not callable
