  To use the global variable in the Python function, define it as a global variable inside each function that assigns a value to it. To create a variable, write the variable name = assign the value to the right = sign the variable name.

  # example of a global variable       a = 120   # defined outside the function       b = 110              def sum():           c = a + b  # Using global variables           print("Sum of a and b is :", c)              def sub():           d = a - b   # using global variables           print("Substraction of a and b is :", d)                     sum()      sub()
