Test a computer program or algorithm : Handling User Errors

The video tutorial covers the concept of debugging, its historical origins, and its significance in programming. It provides a detailed guide on setting up and using the PyCharm debugger, including setting breakpoints, using the expression evaluator, and stepping through code. The tutorial emphasizes the importance of debugging as a primary activity in development and offers best practices for effective debugging.

What historical event led to the coining of the term 'debugging'?

• A computer virus spreading in the 1980s

• A bug found in the first version of Windows

• A moth causing a short circuit in a computer

• A software crash during a NASA mission

What is the primary purpose of setting a breakpoint in debugging?

• To speed up the execution of the program

• To stop the program at a specific point for inspection

• To automatically fix errors in the code

• To compile the code more efficiently

In PyCharm, what color indicates the current line being executed during debugging?

• Red

• Green

• Blue

• Yellow

What tool in PyCharm allows you to run arbitrary Python code during debugging?

• Code Formatter

• Expression Evaluator

• Syntax Checker

• Variable Inspector

Which button in PyCharm's debugger allows you to move to the next line in the current scope?

• Continue

• Step Over

• Step Into

• Step Out

What happens when you press 'Step Into' during debugging in PyCharm?

• It stops the program execution

• It enters the function being called

• It skips the current function

• It exits the current function

What is the significance of the 'Step Out' button in PyCharm's debugger?

• It evaluates the current expression

• It restarts the debugging session

• It exits the current function and returns to the caller

• It moves to the next line in the current function

Why is it important to go slowly and set breakpoints while debugging?

• To ensure the program runs faster

• To avoid missing any errors

• To automatically fix all bugs

• To compile the code more efficiently

What does the yellow background in the PyCharm debugger's call stack indicate?

• Syntax errors

• Unreachable code

• Python internal functions

• User-written code

What should you do if you encounter a key error during debugging?

• Delete the problematic code

• Restart the program without changes

• Set a breakpoint and inspect the variables

• Ignore the error and continue
