Python adoption is widespread because of its clear syntax and readability. Used often in data analytics, machine learning (ML) andweb development, Python yields code that is easy to read, understand and learn. Python's indentation requirements for source statements help make the code consistent and...
pandas is an open-source software library built on Python for data analysis and data manipulation. The pandas library provides data structures designed specifically to handle tabular datasets with a simplified Python API. pandas is an extension of Python to process and manipulate tabular data, impleme...
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 ...

Python is dynamically typed unlike C++ and Java, as a result, variable types are inferred atruntime. This simplifies development but potentially at the cost of performance. Python uses an automatic garbage collector like Java and doesn't use the C++ const keyword. ...
PEP 0238: An expression like 1/2 returns a float. Use 1//2 to get the truncating behavior. (The latter syntax has existed for years, at least since Python 2.2.) The sys.maxint constant was removed, since there is no longer a limit to the value of integers. However, sys.maxsize ca...

While using the ArcGIS API for Python, we primarily work with well-known IDs called as wkid. For instance, the wkid of Web Mercator PCS explained above is 3857. Occasionally, you might see a latestWkid being used. The latestWkid represents the current wkid value associated with the same ...
As ofsos-3.9and later, sos supports the--uploadoption to automatically upload an archive once it is generated. Note that a local copy of the archive will still exist. This option requires the use of thepython3-requestspackage, which is defined as a weak dependency for the sos rpm. Systems...
