Scope of the variables in python

Scope of the variables in python:

 we are following the rule: LEGB

L means Local

E means Enclosing

G means Global

B means Builtin

Example:

x="global x"
y="global y"
z="global z"
def f1(x):
    y="local y"
    z="local z"
    x="local x"
    print(y)
    print(z)
    print(x)

f1("enclosing z")

Output:

loacl y
local z

local x

Example:

x="global x"
y="global y"
z="global z"
def f1(z):
    y="local y"
    print(y)
    print(z)
    print(x)

f1("enclosing z")

Output:

loacl y
enclosing z

global x

Example:

x="global x"
y="global y"
z="global z"
def f1(z,x):
    y="loacl y"
    print(y)
    z=20
    print(z)
    print(x)

f1("enclosing z","enclosing x")

Output:

loacl y
20

enclosing x
