I want to tell you a story about the suffix array. For a while, I was interviewing at a company in Seattle, when I was curious about how to most effectively create an executable binary file diff . My research brought me a suffix array and a suffix tree. The suffix array simply sorts all the suffixes of the string and stores them in the ordered list. The suffix tree is similar, but more like a list BSTree . These algorithms are fairly simple, and once
Today, we can see that there are fork sub-processes in others' source code to operate data. However, as fork does not exit in time, the number of Python processes in the system increases and the number of sub-processes increases. I wrote the test code for the fork process under Python (to illustrate this problem is not necessarily appropriate ):
Def fork (a): def now (): import datetime return datetime. d
Python code is used to create a configure file in lua, and lua is always used as a config file or a file that carries data. the advantage is that lua can be well read and no extra parsing code is required, you can also read environment variables and condition judgments in configure files.
Use loadfile and setfenv in lua)
Python:
Cat config. pybar = 10foo = 1

This article mainly introduces how to create a simple hacker in Python. you can learn Python threads, call cmd command lines, and open web pages. the code for using it is as follows:
Import webbrowser as webImport timeImport OS
Count = 0While count Count = count + 1# Blog you want to refreshWeb. open_new_tab ("Here is the blog address ")Time. sleep (1)Else:OS
def __next__ (self):
if Self.index = 0:
raise stopiteration
self.index-= 1
Get the result:

In the For Loop, the ITER () method is invoked first, an iterator object is called, and then the next () method of the Iterator object is invoked, returning a value at a time.

three ways to create iterators:
1. Define a container and add the iter() and next() methods (the next () method in

The last time I used ironpython 2.0 A1, I downloaded the official version 2.0.1, and found that the change was not small... I am out of date.
The original code is no longer running normally, so I adjusted it on the official version 2.0.1.

Python provides multiple modules for creating sub-processes. I prefer to use the subprocess module because the python manual contains the following:
This module intends to replace several other, older modules and functions, such as: OS. System, OS. Spawn *, OS. popen *, popen2. *, commands .*
Subprocess is used to replace some old modules and functions, such as OS. System, OS. Spawn *, OS. popen *, popen2.
("Exit", exit) ...

Attempt to execute python -m yosh.shell . Now you can enter exit gracefully to exit the program.
The final idea
I want you to enjoy yosh the process of creating (your own shell) as much as I do. But my yosh version is still in its early stages. I did not deal with some extreme situations that would cause the shell to crash. There are many built-in commands that I don't have covered. To improve performance, some non-built-in com
