Let’s compare the naive Python loop versus the NumPy Where clause — examine for readability, maintainability, speed, etc. # Fictitious scenario:from sklearn.datasets import fetch_california_housingcalifornia_housing = fetch_california_housing(as_frame=True)X ...
This would produce the following result − MyException caught C++Exception Here,what()is a public method provided by exception class and it has been overridden by all the child exception classes. This returns the cause of an exception.

Because it is a Python object, it cannot be used in any arbitrary NumPy/Pandas array, but only in arrays with data type 'object' (i.e. arrays of Python objects): import numpy as np import pandas as pd vals1 = np.array([1, None, 3, 4]) vals1 This dtype=object means that ...
The first thing you might notice is that there is no explicit lock, and there is no explicit database transaction. Multiple processes can now safely create short URLs without getting an IntegrityError. According to this quote from the Python glossary, this approach is also much more "pythonic"...
As usual, you should always read the man page of the scripts you're calling, to see what the conventions are for each of them. If you've programmed with a language like Java or Python, then you're most likely familiar with their exceptions, different meanings, and how not all of them...
