Define Variables

Define Variables in Python

Multiple Assignments
Multiple assignments can be made in a single statement.

Example 1
a, b, c = 5, 3.2, "Hello"
print a,b,c

Result

Example 2
If we want to assign the same value to multiple variables at once, we can do this as

x = y = z = "same value"
print x;print y;print z

Result


Variables
Python supports int,float and compile. It also support String,List,Tuple and Dictionary
Example
a=10
b=-10
c=10.00
d=10.9098
e=-10.98
print a,b,c,d,e

String

Example
a_string=”hello”
print a_string     # output hello

List
A list contains items separated by commas and enclosed within square brackets ([]).

Example
a_list=[‘a’,’b’,’c’]
print a_list[0] # output a
Tuple
It is readonly. Same as  list contains items separated by commas and enclosed within ().

Example
a_tuple=('a','b','c')
print a_tuple[1]

Dictionary
 It is used to define data records. Dictionaries are enclosed by curly braces ({ }) and values are accessed using square braces ([]).

Example
employeetable = {'name': 'kumar','empcode':'a01', 'dept': 'sales'}
print employeetable.keys()[2],employeetable.values()[2]

name=(['arun','sharma','arvind'],['sunil','ashok'])
print name[1]
print name[1][1]

Result
