This article shows you what the Python function is to get help in the actual operation, the content is concise and easy to understand, absolutely can make your eyes bright, through the detailed introduction of this article, I hope you can get something.

Python function is a widely used computer language, if you want to get help in writing and running Hello World in Python, you can have a better understanding of Python function in this respect through the following article. The following is an introduction to the article.

Get help

If you need quick information help from a Python function or statement, you can use the built-in help function. It is especially useful when you use the command line with a prompt. For example, run help (str), which shows the help of the str class. The str class is used to hold all kinds of text (strings) used by your program. The class is explained in detail in later chapters on object-oriented programming.

Note: press Q to exit the help. Similarly, you can get information about almost everything in the Python function. Use help () to learn more about help itself!

If you want help with operators like print, you need to set the PYTHONDOCS environment variable correctly. This can be easily done with the env command in Linux/Unix.

$env PYTHONDOCS=/usr/share/doc/python-docs-2.4.3/html/python

Python 2.3.4 (# 1, Jul 26 2006, 16:42:40)

[GCC 3.4.2 20050110 (Red Hat 3.4.2-6.fc3)] on linux2

Type "help", "copyright", "credits" or "license" for more

Information.

> help ('print')

You should have noticed that I deliberately used quotation marks on "print" so that the Python function could understand that I wanted help on "print" rather than printing.

Note that the location I use is in Fedora Core 3 Linux, which may vary from release to release and from release to release.

The above is the solution for the Python function to get help in practice. Have you learned the knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
