Can you explain what the global keyword is in programming?
The global keyword is used to declare a variable that is accessible throughout the entire program, not just within a function.
Why would I want to use global variables?
Global variables can be useful for sharing data between functions without passing them as parameters, but they can also lead to code that is harder to debug.
Are there any downsides to using global variables?
Yes, global variables can cause conflicts and make your code less modular, which can lead to maintenance challenges.
What are some best practices for using global variables?
It's best to limit their use, keep them well-documented, and consider alternatives like passing parameters or using classes.
