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 # declare a to be a global
a = value # this sets the global value of apython local variables
'''Local variables are those that are defined in a block '''
a = 1 #This is NOT a local variable, this is a global variable
def add():
b = 1 #This IS a local variable
print(b)
add()
#If we tried to print(b) outside of the add() function, we would get an errorCopyright © 2021 Codeinu
