Strings that are not composed of ASCII letters, digits or underscores, are not interned. This explains why 'wtf!' was not interned due to !. CPython implementation of this rule can be found hereWhen a and b are set to "wtf!" in the same line, the Python interpreter creates a new ob...
both x & y axis limits are a bit large and can be narrowed down, the title is not exactly what we may like, etc.). We will now develop a more personalized plot for all the 12 months as follows:
Generators are iterators, a kind of iterable you can only iterate over once. Generators do not store all the values in memory, they generate the values on the flyyieldyield is a keyword that is used like return, except the function will return a generator. To master yield, you must ...

The geometry we just created is invalid, yet the API allowed you to still create it. This because, the API does not check for validity in an eager fashion. Rather it checks when is_valid() is called, in an on-demand fashion. This is for performance reasons. map1 = gis.map() map1...
Here’s a creative demonstration where we create a new context manager to print out performance (timing) data.This might be useful for quickly testing the time cost of code snippets, as shown in the following example. The numbered notes are intentionally not in numerical order in the code. ...
Unfortunately, many stack traces do not contain in-app frames, thus, many Sentry features are not available (e.g. SCM linking, suspect commit). This tracks using the code mappings derivation system to automatically add the code mappings and stack trace rules to mark in-app frames as such....
In this post, recipes related to various aspects of concurrent programming are presented, including common thread programming techniques and approaches for parallel processing.
2). Parameter objects form the foundation of the software, containing a value, bounds for that value, and a vary attribute (i.e., is the value allowed to vary in a fit?). Surface regions within StructureSE are represented by ComponentSE objects. The simplest ComponentSE is a SlabSE, ...
