Variable Types in Python 3




What is Variable



Variable reserved memory location to store value 


The Python interpreter allocates memory and decides how much memory reserved based on the data types 

Data types can be store as Integers, decimals or characters 





Assigning values to variables


Do not need to declare data type at the time of variable declaration .

Python automatically declare data type when a value is assign to the variable.

The equal sign ( = ) is used to assign value to variables.

Left operator is the name of variable and Right Operator is the value stored in the variable

For Example:

StudentMark = 98     # An integer type

StudentCgpa = 9.90   # float type

StudentName = “John Doe”  # String type

# Now Print value

print(StudentMark) #
Output 98 

print(StudentCgpa
#Output 9.90

print(StudentName
#Output John Doe 




Multiple Assignment


Python allows you to assign several variables at once

Example:

a = b = c = 5

print(a)   
#Output: 5

print(b)  
#Output : 5

print(c)  
#Output: 5

as well as you can assign multiple object to multiple variables.

For Example:

a, b, c = 1, 2.0, “John Doe”

print( a, b, c) # Output: 1 2.0 John Deo
