It is not easy to access everything in Python, and there will be differences in the length of the variables. However, the way we define the variable plays a vital role in determining the location and the duration of accessing the variables. The part of the program that allows you to access the variable is called the Scope while the time taken for accessing the variable is a lifetime.

Global variables refer to the variables defined in the primary file body. These variables are visible throughout the file and also in the file that imports specific data. As such, these variables cause a long-term impact which you may notice when working on your program. This is the reason why it is not good to use global variables in the Python program. We advise programmers to add stuff into the global namespace only if they plan to use them internationally. A local variable is a variable defined within another variable. You can access local variables from the region they are assigned. Also, the variables are available in the specific parts of the program.
