Python is Dynamic:
- Every programming language is used to develop applications
- Application is used to store and process the data.
- Generally we allocate memory to variables in 2 ways
- Static memory allocation
- Dynamic memory allocation
Static memory:
- Static means “fixed memory”
- The languages which are supporting primitive types allowed allocating static memory.
- Primitive variable size and type are fixed.
- Primitive variable stores data directly.
- Compiler raises error when data limit or type is deviated from specified.
Dynamic memory:
- Python is dynamic.
- Dynamic memory means type and size of data can vary.
- Python can store information in Object format.
- Dynamic variables cannot store the data directly.
- Dynamic variables store the reference of Object which holds data.
In Python, object location changes every time when we modify the data.
