Code Your First Python Program (Quiz)

The course was desingned by keeping in mind for beginners. It really helps me as a beginner and from non -IT back ground.

So far, so good.

This course is very good for beginners like me.

I don’t understand. I have competed the Quiz, but it shows as Not Completed. I passed the Quiz 4 times, but yet it’s the same.

@john You can take quizzes as many times as you want. When you get to the summary of a quiz, it says the following at the bottom:

Click the Mark as Completed button on the course lesson once you feel ready to move on. You can retake this quiz as many times as you like.

So, to mark the corresponding video lesson as complete, you can manually click the button to the left of the Supporting Material dropdown.

Okay, thaks. Done !!!

Mixed case is referred to as camel case if it starts with lower case letters or pascal case if it’s capitalized in other languages. Well, that’s my experience anyway.

The coding sections of the quiz are very creative. I appreciate the interactive questions.

I got the quiz 100%.

I included the colon as of the Hello world text to print

Hello, How would you define a traceback error compared to a syntax or runtime error, it’s still unclear to me.

Kind regards

@emmanuel a traceback isn’t a separate type of error in itself, but rather the detailed report Python provides when an error occurs. The traceback shows the sequence of function calls that led to the error, helping to pinpoint where and why something went wrong.

To compare with syntax errors and runtime errors:

Syntax Error

This occurs when Python’s parser encounters incorrect syntax. It means you’ve written something that doesn’t follow Python’s grammar rules, like missing a colon, having unmatched parentheses, or using an invalid keyword:

>>> if True
SyntaxError: expected ':'

Runtime Error

This occurs when an error happens while the program is running. Even if the syntax is correct, the program can fail due to issues like dividing by zero, trying to access a variable that doesn’t exist, or performing invalid operations:

>>> print(1 / 0)
ZeroDivisionError: division by zero

Traceback

This is a report that Python generates when it encounters a runtime error. It shows the call stack of what the program was doing when the error occurred, including the line numbers and function calls that led to the error:

>>> def divide(a, b):
...     return a / b
...
>>> divide(1, 0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in divide
ZeroDivisionError: division by zero

So, to sum this up:

• Syntax errors prevent the code from even starting.
• Runtime errors occur during execution and stop the program.
• A traceback shows where and why a runtime error occurred, which can help you debug the error.

@Martin Thank you very much this is very clear. To be honest, I did not expect anyone to answer so quickly but you did it and that is wonderful. Last week, I attended a course on another platform as they had a “free trial week”. I learnt about “Devops” but there was a section on advanced python which covered advanced Python concepts like exceptions. I understood the general idea but did not understand fully how useful this can be. I’ll give a try at the resource you highlighted here on this site.

@emmanuel great! :D Glad this made sense and hope you’ll find more useful content on our site!
