Traceback is mainly used to print stack traces of a python program. This package provides a standard interface for the user to format and extract as they see fit.
Because there are three values in the list but we only assign them to two variables, we are receiving this traceback. Python is therefore unable to determine which fruit we prefer - Apple, Mango, or Orange. We can resolve this quickly:...

Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...

other things, this release brings support for f-strings, which make string formattingmucheasier and more intuitive. In the code editor, embedded expressions in an f-string (enclosed in curly braces) get a slightly different background color, and code completion is available within those ...
The programmer must add an exception handler in the code; if the handler is found, the exception is processed; otherwise, Python’s default exception handler prints the details of the error and terminates the program. Python organizes exceptions with a base class called BaseException, from which...
