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.
Traceback (most recent call last): File "/home/cg/root/86756/main.py", line 2, in <module> my_string.reverse() AttributeError: 'str' object has no attribute 'reverse' SolutionNow the code will run without any errors, and the output will be !tnioP slairotuT, which is the reversed...
In this tutorial, you'll explore Python's __pycache__ folder. You'll learn about when and why the interpreter creates these folders, and you'll customize their default behavior. Finally, you'll take a look under the hood of the cached .pyc files.
So if we try to call thisffunction, which always calls itself, we'll see atracebackwhich says aRecursionErrorexception was raised: >>>deff(n):...print(n)...f(n+1)...>>>f(0)0123...995Traceback (most recent call last):File"<stdin>", line1, in<module>File"<stdin>", line3...

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:...
