Working of Python: In python, variables are stored as references to a value object. Each time you change the value, the variable’s reference memory address changes. Python frontloads some commonly used values in memory. Each variable referring to that value actually stores that memory address of the value. Multiple variables/identifiers can refer to a single …
Data Type: It specifies the type of data and associated operations of handling it. Different set of operations are applicable on different types of data.

Error/Bug: Error is a mistake/bug in the program which makes the behavior of the program abnormal. It prevents a program from compiling and running correctly. So, the errors must be removed from the program for the successful execution of the program. Programming errors are also known as the bugs. These errors are detected either during …
Dictionary: Dictionaries are used to store multiple items in key : value form separated by a , (keys and values may be of same type elements ie homogeneous data types or different types elements ie heterogeneous data types) in a single variable.
