The developers of IPython absorbed the basic concepts of the standard interpreter, made a lot of improvements on this basis, and created an amazing tool. It says this on its homepage: "This is an enhanced interactive Python shell." It has tab completion, object introspection, a powerful history mechanism, embedded source code editing, integrated Python debugger, and %run mechanism. Macros, the ability to create multiple environments and invoke system shells.
The biggest difference between IPython and standard Python is that Ipython numbers each line of the command prompt. (Recommended learning: Python video tutorial)
As shown below:
The difference between python shell and ipython :
python shell cannot save history after exiting;
ipython history is automatically saved:
is saved in Under the history.sqlite file:
You can use "_", "__", and "___" to call the last three records;
Python shell does not support tab auto-completion;
ipython supports tab completion;
python shell cannot quickly obtain class and function information;
ipython displays the object signature, document string, and code location through "?", and displays the source code through "??";
python shell cannot directly execute shell commands and needs to use sys ;
ipython calls system commands through "!", such as "!uptime";
(5) Others
ipython has many magic function, can be enumerated by using %lsmagic;
%run: run python file
�it: use the editor to open the current function for editing
%save: save a certain Save some history records to the file
�bug: Activate the debug program
%timeit: Get the program execution time
%paste: Get the clipboard file and execute it, best With %cpaste, you can interrupt it with Ctrl C

Mathematical operations of the entire array in NumPy can be efficiently implemented through vectorized operations. 1) Use simple operators such as addition (arr 2) to perform operations on arrays. 2) NumPy uses the underlying C language library, which improves the computing speed. 3) You can perform complex operations such as multiplication, division, and exponents. 4) Pay attention to broadcast operations to ensure that the array shape is compatible. 5) Using NumPy functions such as np.sum() can significantly improve performance.

In Python, there are two main methods for inserting elements into a list: 1) Using the insert(index, value) method, you can insert elements at the specified index, but inserting at the beginning of a large list is inefficient; 2) Using the append(value) method, add elements at the end of the list, which is highly efficient. For large lists, it is recommended to use append() or consider using deque or NumPy arrays to optimize performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
