Python In Practice - 15 Projects to Master Python - locals( )

The video tutorial explains the concepts of global and local variables in Python. It begins with an introduction to global variables, which are defined outside of functions and classes, and how they can be accessed throughout the module. The tutorial then moves on to local variables, which are defined within functions and are only accessible within those functions. The use of global and local functions to access these variables is demonstrated, along with a practical example to illustrate the concepts. The tutorial concludes with a summary of how to effectively use these variable scopes in Python programming.

What are global values in Python?

• Values that are only accessible within a loop

• Variables defined inside a function

• Variables defined outside any function or class

• Predefined values by the user

Which of the following is true about local variables?

• They are predefined by the Python interpreter

• They are only accessible within the function they are defined in

• They are defined outside of functions

• They can be accessed from anywhere in the program

What happens if you try to access a local variable outside its function?

• An error will occur indicating the variable is undefined

• The variable will be accessible but with a default value

• The variable will be automatically converted to a global variable

• The program will run without any issues

How can you access local variables within a function?

• By defining them as global variables

• By using the print() function

• By using the locals() function

• By using the global keyword

What does the locals() function do?

• It deletes all local variables

• It returns a dictionary of the current local symbol table

• It prints all global variables

• It converts local variables to global variables
