Variables in python

What is a variable?

Variable is a memory block in RAM. Python is dynamically typed language so we don’t have to define the data type of the variable.

How to define variable in python?

Syntax:
       variable_name = value
Example1:
       num = 100 
#Here num is variable which is holding 100 as value.
# In order to check data type of variable we can use type built-in function.
       type(num)
#OUTPUT
       int
Example2:
       name = 'viraj' 
# Now name string type of variable based on value
       type(name)
#OUTPUT
       str
Example3:
       amount = 987.99
       type(amount)
#OUTPUT
       float
