The code you type interactively is never stored in a file, so you can’t run it again without retyping it from scratch. Cut-and-paste and command recall can help some here, but not much, especially when you start writing larger programs. To save programs permanently, you need Python ...
1. It requires the intrinsics to be available, which means that I need to store them some how, either in a bag or reload later 2. A bag is not relevant since I store only a small subset of frames in memory in response to some external event (hardware triggers) and then save th...

You already used one of them, the Python interactive interpreter, also known as the read-evaluate-print loop (REPL). Even though the REPL is quite useful for trying out small pieces of code and experimenting, you can’t save your code for later use. To save and reuse your code, you ...
There are a variety of ways to tell Python to execute the code you type. This chapter discusses all the program-launching techniques in common use today. Along the way, you’ll learn how to type code interactively, and how to save it in files to be run with system command lines, icon...
To save an image to a directory in Python using the Pillow library, first, import theImagemodule from Pillow and theosmodule. Open the image usingImage.open('image_name.jpg'), define your target directory, and ensure it exists usingos.makedirs(directory, exist_ok=True). Finally, save the...
A Python script or program is a file containing executable Python code. Being able to run Python scripts and code is probably the most important skill that you need as a Python developer. By running your code, you'll know if it works as planned.

2. Save NumPy Array to .NPY File (binary) Sometimes we have a lot of data in NumPy arrays that we wish to save efficiently, but which we only need to use in another Python program. Therefore, we can save the NumPy arrays into a native binary format that is efficient to both save an...
