Python also has a specific category of exceptions that represent warnings to the programmer. Warnings come in handy when you need to alert the user of some condition in a program. However, that condition may not
raise_for_status(): This method raises an exception for HTTP errors (for status codes 4xx, 5xx). Example – try: response.raise_for_status() except requests.exceptions.HTTPError as e: print(f"HTTP error occurred: {e}") iter_content(): It is used to stream content for e.g downloadin...
Exceptions areusedby "raising" them and they may be handled by surrounding exception-raising code with atry-exceptblock. When an exception is not handled, the Python process exits, printing a stacktracebackin most cases. For more on exceptions, seeraising exceptions in Pythonandhandling exceptions...
If the list is updated within the loop like removing elements it can cause the loop to go past the updated list length raising the error. Example: In the below code, the second iteration removes the element, reducing the list’s length to 2, but still, the loop proceeds one more time,...
You used raise previously in the miles_per_gallon() example. When you catch the TypeError, you re-raise the exception after printing a message to the screen. For more on raise, check out Python’s raise: Effectively Raising Exceptions in Your Code.The...

re.IGNORECASE (re.I): This flag makes the search case-insensitive, allowing the function to match strings regardless of their case. For example, it would match “python”, “Python”, “PYTHON”, or any other variation of the string. ...
Note: Python avoids much of the tension of the "error codes vs exceptions" argument. Between the ability to return multiple values from a function and the ability to return values of different types (e.g.Noneor something similar in the error case) the argument is moot. But this is besides...
