Data persistence modules save Python data between program runs. These tools range from simple file-based storage to complex serialization systems, offering different tradeoffs between speed, compatibility, and human readability. Storage format comparison: FormatHuman ReadableCross LanguagePerformance pickle No...
Note: If you create a new localvariableinside a function with the same name as a global variable, it will not override the value of a global variable. Instead, the new variable will be local and can only be used inside the function. The global variable with the same name will remain un...
Git stash stores the changes you made to the working directory locally (inside your project's .git directory;/.git/refs/stash, to be precise) and allows you to retrieve the changes when you need them. It's handy when you need to switch between contexts. It allows you to save changes t...

A variable can be either mutable or immutable. If the variable’s value can change, the object is called mutable, while if the value cannot change, the object is called immutable. We will learn the difference between mutable and immutable types in the later section of this article. Also, ...
Note that the Python documentation draws a distinction between parameter (the variable name used) and argument (the actual object which will be passed-in to the function), but this distinction is often ignored by Python users (we often say "argument" when "parameter" might be more correct)....

Python supportsmodularity, in that you can break large chunks of code into smaller, more manageable pieces. You do this by creatingfunctions, which you can think of as named chunks of code. Recall this diagram fromChapter 1, which shows the relationship between functions, modules, and the stan...
Notice that even though the number of characters is different between Real and Python, MATLAB is able to create the string array. On line 6 you are checking the size of the string array, which shows that there are 2 rows and 1 column, as expected....
In native Python extension modules, many of these variables are of type PyObject (which is a typedef for _object), or a few other fundamental Python types. In mixed-mode debugging, these values present another child node labeled [Python view]. To view the variable's Python representation...
