# errno - pydoc - phpman

> **TLDR:** Look up errno names and descriptions.
>
- Lookup errno description by name or code:
  `errno {{name|code}}`
- List all errno names, codes, and descriptions:
  `errno {{-l|--list}}`
- Search for code whose description contains all of the given text:
  `errno {{-s|--search}} {{text}}`
- Search for code whose description contains all of the given text (all locales):
  `errno {{-S|--search-all-locales}} {{text}}`

Help on built-in module errno:

## NAME
    errno - This module makes available standard errno system symbols.

## MODULE REFERENCE
    <https://docs.python.org/3.10/library/errno.html>

    The following documentation is automatically generated from the Python
    source files.  It may be incomplete, incorrect or include features that
    are considered implementation detail and may vary between Python
    implementations.  When in doubt, consult the module reference at the
    location listed above.

## DESCRIPTION
    The value of each symbol is the corresponding integer value,
    e.g., on most systems, errno.ENOENT equals the integer 2.

    The dictionary errno.errorcode maps numeric codes to symbol names,
    e.g., errno.errorcode[2] could be the string 'ENOENT'.

    Symbols that are not relevant to the underlying system are not defined.

    To map error codes to error messages, use the function os.strerror(),
    e.g. [os.strerror(2)](https://www.chedong.com/phpMan.php/man/os.strerror/2/markdown) could return 'No such file or directory'.
