Data types and variables in Python


In Python, variables are used to store a result or a value in the computer's memory during the execution of a program. Variables enable easy access to a specific location on the computer's memory and enables writing user-readable code.

The person would be asked to fill out an application form with relevant information, including their name, department, and emergency contact information. The form would have the requisite fields. This would enable the office manager to refer to the form while creating a new ID card.

Similarly, variables simplify code development by providing means to store information in the computer's memory. It would be very difficult to write code if one had to write code keeping the storage memory map in mind. For example, it is easier to use the variable called name rather than a specific memory address like 0x3745092.
