the vast majority of CPU-intensive code is concentrated in a few hot spots—a version of thePareto principle, also known as the “80/20” rule. Thus, most of the code in a Python application doesn’t need to be performance-optimized, just a few critical pieces. You can incrementally...
*.py上的text需要转换为byte code,此时,Python的虚拟机才能运行这个byte code。 Python code goes through 2 stages. First step compiles the code into .pyc files which is actually a bytecode. Then this .pyc file(bytecode) is interpreted using CPython interpreter. References: https://stackoverflow....
The classic implementation of Python is called "CPython." There are two ways Python can interpret the code written in it. One way is through the interactive mode that is having aPython prompt& the other way is through the script mode. ...

Why directory __pycache__ is not created after launch?, the code is works of course and I see that the directory "__pycache__" (where should store the compiled programme " sc.cpython-36.pyc ") is created in the same directory where " sc.py " is placed. But if I run the script...

If the items in a tuple are mutable, then you’ll be able to change them even if the tuple itself is immutable. In other words, the immutability of Python tuples refers to the references it directly holds. It doesn’t extend to the referenced objects themselves. In general, putting mutab...
