Python Variables

Creating Variables

Variables are containers for storing data values.

Unlike other programming languages, Python has no command for declaring a variable.

A variable is created the moment you first assign a value to it.

(1)

x = 5

y = "Rajeev"

print(x)

print(y)

(2)

x = 4

x = "gorgeous"

print(x)

(3)

x = "John"

print(x)

#double quotes are the same as single quotes:

x = 'John'

print(x)

(4)

#Legal variable names:

myvar = "John"

my_var = "John"

_my_var = "John"

myVar = "John"

MYVAR = "John"

myvar2 = "John"

#Illegal variable names:

2myvar = "John"

my-var = "John"

my var = "John"

Assign Value to Multiple Variables

Python allows you to assign values to multiple variables in one line:

(5)

x, y, z = "GRAPS", "Apple", "mango"

print(x)

print(y)

print(z)

(6)

x = y = z = "Orange"

print(x)

print(y)

print(z)

(7)

x = "nice Rajeev"

print("Python is " + x)

(8)

x = "Python is "

y = "good"

z = x + y

print(z)

(9)

x = 5

y = 10

print(x + y)

Global Variables

Variables that are created outside of a function (as in all of the examples above) are known as global variables.

Global variables can be used by everyone, both inside of functions and outside.

(10)

x = "Rajeev Ranjan Tiwari"

def myfunc():

print("Python is " + x)

myfunc()

(11)

x = "awesome"

def myfunc():

x = "RAJEEV"

print("Python is " + x)

myfunc()

print("Python is " + x)

(12)

def myfunc():

global x

x = "RAJEEV"

myfunc()

print("Python is " + x)

(13)

x = "good"

def myfunc():

global x

x = "nice"

myfunc()

print("Python is " + x)
