Python variables are containers that store data values. Variables are created by assigning a value without declaring the variable type. The type of a variable can be specified during assignment or using the type() function. Strings can be declared using single or double quotes and variable names are case-sensitive. Python supports numeric data types like integers, floats, and complex numbers. Random numbers can also be generated using the random module.

2. Python Variables
 Variables are containers for storing data values.
HOW TO CREATE VARIABLES:
 Python has no command for declaring a variable.
 FOR EX:
a=5
b=“radhika”
print(a)
print(b)
Output:----
5
radhika

3.  If you want to specify the data type of a variable, this can be done with casting.
for ex:
a=int(5)
b=str(5)
c=float(5)
output:
5
5
5.0
TYPE() FUNCTION:---
FOR EX:-
a=5
print(type(a))
Output:
<class 'int'>

4. Single and double quotes
 String can be declared either by using single and double quotes.
 For ex:
a=‘hello’
b=“hello”
print(a)
print(b)
Output:
hello
hello
 Variable names are case-sensitive
 a = 4
A = “hello” #A will not overwrite a

5. Python Data Type

6. Python Numbers
For ex: a=1 a=1.5 a=1j
Random number:
import random
print(random.randrange(1, 10))
Output:
4
