A single line of Python code can do many things

Xiaobian himself is a Python development engineer, I spent three days to organize a set of Python learning tutorials, from the most basic Python scripts to Web development, crawler, data analysis, data visualization, machine learning, etc., these materials can be “click” to get the friends who want

Today I’m going to show you what you can do with just one line of Python code or command

The HTTP server

The FTP server

Here’s another example: You can use Pyftpdlib to implement file transfers directly from an FTP server:

Formatted Json

Sometimes you might encounter Json data that looks like this:

A little upset? You can format json using json.tool:

python -c

With this -c argument, simple Python code can be used directly from the terminal:

One line of code implements the function

Lambda allows you to implement an anonymous function in a single line of code. For example, if you want to evaluate an element in a list, you can do this:

Variable exchange

A line of code swapping two variables is a cliche:

One line of code generates the list

When you need to append an empty list by frequently evaluating a number, it is more convenient to do so:

You can also read files in this way

Pprint can be used for better output:

Analysis of the performance

You can use cProfile to analyze your PY performance:

if.. in.. else

Sometimes simple checks can be done with a single line of code, such as if an element is in a list or not, and you can do something about it:
