Datatype in python programming language

Data types indicates the type of  value and how the value can be used in programs. Data type is used to allocate memory location in memory. For future use of stored data, variables are given a unique name to identify different memory locations. There is no need to declare variables before using them in python, unlike other languages. However, access to the data (content) is via variable name (variable identifiers) in python.

Eg

your_age=34

 

• INT – int represents negative and positive integer value without decimal point

• Float – floating point represents negative and positive values represented with decimal point.
