Python Variables - SVRR TECH

Variables are created when we assign a value to it. Based on the data type of a variable, the interpreter allocates memory.

In Python the variable declaration happens automatically when you assign a value to a variable, = is symbol used to assign values to it.

Eg:

a=10
b=12.34
c=”Hello”
d=’A’
print(a)
print(b)
 print(c)
 print(d)

OUTPUT:

10
12.34
Hello
A


In variables we can use single quotes.


Eg:
q=’Hello’
 print(q)

OUTPUT:

Hello

Assigning multiple values to a variable:

Eg:
x,y,z="regu","ram","sv"
 print(x)
 print(y)
 print(z)

OUTPUT:

regu
ram
sv

Assigning same values to multiple variables:

Eg:

a=b=c="svrr tech"
 print(a)
 print(b)
 print(c)

OUTPUT:

svrrtech
svrrtech
svrrtech

Adding two variable using python:

Eg:

x=”SVRR”
y=”TECH”
z=x+y
print(z)

OUTPUT:

SVRR TECH

Note: In python we cannot add a integer with a variable.

Eg:

x=12
y=”SVRR”
z=x+y
print(z)

OUTPUT:

Error

Global variable:

Variables which are defined outside of a function then it is a global variable.

Eg:

a=10
 def myfun():
   print(a)
 myfun()

OUTPUT:

10
