variable scope python code example

Example 1: variables in python

# Variables in Python are used to store some data in it and use it over and
# over again 
# Variables can store Strings, Integers, Floats, Booleans
var_string = "Hello World!"
var_integer = 1234567890	# any number
var_float = 3.14159			# any number with decimal value
var_boolean = True          # True or False

Example 2: how does scope work in python

a = 5
b = 3

def f1():
  a = 2
  print(a)
  print(b)
  
print(a)   # Will print 5
f1()       # Will print 2 and 3

Example 3: python variable scope

a = 5

def f1():
  a = 2
  print(a)
  
print(a)   # Will print 5
f1()       # Will print 2
