Shunto touch melon, open the github of the electrum, we find the following code in the electrum/electrum/ecc.py.
check_rectangles function is the bottleneck part! It loops through a large number of Python objects, which can be slow because the Python interpreter does a lot of work with each iteration (looking for area-seeking methods in the class, packaging and decontracting parameters, calling the Python API... )
Remote Trojan functions, including command execution, file upload download, python code execution, information collection, file search and other functions.

Format! Macros are designed to provide familiar formatting methods to users of printf/fprintf functions in C or str.format functions in Python.
Function lambda, map, filter, is an important point of knowledge in Python. In this article, examples will be used to illustrate how lambda, map, and filter functions in Python are used.
Python calls OpenCV to implement mean filtering of the core functions as follows.
The following is the calling model for the calling family of call functions in Solidity.
If that's what pathlib does, it's a good addition to Python -- but it does more -- for example, we can read the contents of a file directly instead of calling functions like open() or close().
