get variable in function python code example

Example 1: python 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 error

Example 2: accessing a variable from outside the function in python

# for accessing a variable from outside the function then create that variable
# as an attribute of the function
def hi():
    # other code...
    hi.bye = 42  # Create function attribute.
    sigh = 10

hi()
print(hi.bye)  # -> 42
