What are the Python workers who make python work more efficiently?
This article mainly introduces the python work to make more efficient Python small workers have what, have a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to know about it.
As a more and more popular programming language, ython is not only because of its simple language, but also because there are many ready-made packages that can be called directly.
There are plenty of gadgets in python to make your python work more efficient.
1. Fast sharing
HTTP server
SimpleHTTPServer is python's built-in web server, which is shared using port 8000 and HTTP protocol.
To be able to quickly build a HTTP service and shared service on any platform (Window,Linux,MacOS), you only need to build a good python environment.
Python2 version:
Python-m SimpleHTTPServer

FTP server
Ftp sharing requires the support of third-party components, installation commands:
Pip install pyftpdlib python-m pyftpdlib-p port number
Access method: ftp://IP: port.
two。 Decompress
This paper introduces the use of python to extract five compressed files: .gz .tar .zip .rar
Zip
Tar
Gz
Gz typically compresses only one file, all of which often work with other packaging tools. For example, you can package it to X.tar with tar, and then compress it to X.tar.gz.
To extract gz is to actually read out a single file. The Python method is as follows:
Rar
Since rar is usually used under window, an additional Python package rarfile is required.
Installation:
Python setup.py install
Unzip:
Common operations of 3.pip
Pip is a famous package management tool of Python, which is essential in Python development.
Installation
Online installation
Pip install or pip install-r requirements.txt
Local installation:
Pip install / or pip install-use-wheel-no-index-find-links=wheelhouse/
Look up the package
Pip search
Delete package
Pip uninstall or pip uninstall-r requirements.txt
View package information
Pip show
Check whether package dependencies are complete
Pip check
View a list of installed packages
Pip list
Export all installed packages
Pip freeze requirements.txt
4. Conversion between string and Json
Json to str
Json to str
Using the json.dumps method, you can convert a json object to a string.
5. Python reads excel
Steps
Install python official Excel library-> xlrd
Get the Excel file location and read
Read sheet
Read the specified rows and cols content
6. Python screenshot
Python to achieve screenshot function, windows environment, need to use PIL library.
Installation:
Pip install Pillow
Example:
7. Ipython
Finally, it shows a powerful python tool-IPython.
IPython supports automatic completion of variables, automatic indentation, support for bash shell commands, built-in many practical functions and functions
It's a for Humans Python interactive shell, and you don't want to use your own Python shell after using it.
