### Install autopep8 via pip Source: https://pypi.org/project/autopep8/2.3.2 Use this command to install or upgrade the autopep8 package in your Python environment. ```bash $ pip install --upgrade autopep8 ``` -------------------------------- ### Python code before autopep8 formatting Source: https://pypi.org/project/autopep8/2.3.2 Example of unformatted Python code containing inconsistent spacing, deprecated methods, and poor indentation. ```python import math, sys; def example1(): ####This is a long comment. This should be wrapped to fit within 72 characters. some_tuple=( 1,2, 3,'a' ); some_variable={'long':'Long code lines should be wrapped within 79 characters.', 'other':[math.pi, 100,200,300,9876543210,'This is a long string that goes on'], 'more':{'inner':'This whole logical line should be wrapped.',some_tuple:[1, 20,300,40000,500000000,60000000000000000]}} return (some_tuple, some_variable) def example2(): return {'has_key() is deprecated':True}.has_key({'f':2}.has_key('')); class Example3( object ): def __init__ ( self, bar ): #Comments should have a space after the hash. if bar : bar+=1; bar=bar* bar ; return bar else: some_string = """ Indentation in multiline strings should not be touched. Only actual code should be reindented. """ return (sys.path, some_string) ``` -------------------------------- ### Upgrade setuptools Source: https://pypi.org/project/autopep8/2.3.2 Upgrade setuptools to resolve potential DistributionNotFound errors. ```bash $ pip install --upgrade setuptools ``` -------------------------------- ### Run autopep8 with experimental features Source: https://pypi.org/project/autopep8/2.3.2 Enable experimental functionality such as advanced line shortening. ```bash $ autopep8 --experimental ``` -------------------------------- ### Run autopep8 with specific rules Source: https://pypi.org/project/autopep8/2.3.2 Use the --select option to apply only a subset of formatting fixes. ```bash $ autopep8 --select=E1,W1 ``` -------------------------------- ### Configure autopep8 with pyproject.toml Source: https://pypi.org/project/autopep8/2.3.2 Use the [tool.autopep8] section in pyproject.toml for project-specific configuration. ```toml [tool.autopep8] max_line_length = 120 ignore = "E501,W6" # or ["E501", "W6"] in-place = true recursive = true aggressive = 3 ``` -------------------------------- ### Configure autopep8 with pycodestyle Source: https://pypi.org/project/autopep8/2.3.2 Define formatting rules in a pycodestyle configuration file. ```ini [pycodestyle] max_line_length = 120 ignore = E501 ``` -------------------------------- ### Run autopep8 with verbose output Source: https://pypi.org/project/autopep8/2.3.2 Enable verbose progress messages for large files. ```bash $ autopep8 -v ``` -------------------------------- ### autopep8 command-line options Source: https://pypi.org/project/autopep8/2.3.2 List of available flags and arguments for the autopep8 command-line interface. ```text usage: autopep8 [-h] [--version] [-v] [-d] [-i] [--global-config filename] [--ignore-local-config] [-r] [-j n] [-p n] [-a] [--experimental] [--exclude globs] [--list-fixes] [--ignore errors] [--select errors] [--max-line-length n] [--line-range line line] [--hang-closing] [--exit-code] [files [files ...]] Automatically formats Python code to conform to the PEP 8 style guide. positional arguments: files files to format or '-' for standard in optional arguments: -h, --help show this help message and exit --version show program's version number and exit -v, --verbose print verbose messages; multiple -v result in more verbose messages -d, --diff print the diff for the fixed source -i, --in-place make changes to files in place --global-config filename path to a global pep8 config file; if this file does not exist then this is ignored (default: ~/.config/pep8) --ignore-local-config don't look for and apply local config files; if not passed, defaults are updated with any config files in the project's root directory -r, --recursive run recursively over directories; must be used with --in-place or --diff -j n, --jobs n number of parallel jobs; match CPU count if value is less than 1 -p n, --pep8-passes n maximum number of additional pep8 passes (default: infinite) -a, --aggressive enable non-whitespace changes; multiple -a result in more aggressive changes --experimental enable experimental fixes --exclude globs exclude file/directory names that match these comma- separated globs --list-fixes list codes for fixes; used by --ignore and --select --ignore errors do not fix these errors/warnings (default: E226,E24,W50,W690) --select errors fix only these errors/warnings (e.g. E4,W) --max-line-length n set maximum allowed line length (default: 79) --line-range line line, --range line line only fix errors found within this inclusive range of line numbers (e.g. 1 99); line numbers are indexed at 1 ``` -------------------------------- ### Integrate autopep8 with pre-commit Source: https://pypi.org/project/autopep8/2.3.2 Add autopep8 as a hook in your pre-commit configuration. ```yaml repos: - repo: https://github.com/hhatto/autopep8 rev: ... # select the tag or revision you want, or run `pre-commit autoupdate` hooks: - id: autopep8 ``` -------------------------------- ### Run autopep8 with aggressive options Source: https://pypi.org/project/autopep8/2.3.2 Use the --aggressive flag to enable fixes that may change program behavior, such as E711 and E712. ```bash $ autopep8 --aggressive ``` -------------------------------- ### Use autopep8 as a module Source: https://pypi.org/project/autopep8/2.3.2 Programmatically format code using the fix_code function. ```python >>> import autopep8 >>> autopep8.fix_code('x= 123\n') 'x = 123\n' ``` ```python >>> import autopep8 >>> autopep8.fix_code('print( 123 )\n', ... options={'ignore': ['E']}) 'print( 123 )\n' ``` -------------------------------- ### Modify file in place with aggressive formatting Source: https://pypi.org/project/autopep8/2.3.2 Use the --in-place and --aggressive flags to apply formatting changes directly to the specified file. ```bash $ autopep8 --in-place --aggressive --aggressive ``` -------------------------------- ### Python code after autopep8 formatting Source: https://pypi.org/project/autopep8/2.3.2 The same code snippet after being processed by autopep8, showing corrected PEP 8 style compliance. ```python import math import sys def example1(): # This is a long comment. This should be wrapped to fit within 72 # characters. some_tuple = (1, 2, 3, 'a') some_variable = { 'long': 'Long code lines should be wrapped within 79 characters.', 'other': [ math.pi, 100, 200, 300, 9876543210, 'This is a long string that goes on'], 'more': { 'inner': 'This whole logical line should be wrapped.', some_tuple: [ 1, 20, 300, 40000, 500000000, 60000000000000000]}} return (some_tuple, some_variable) def example2(): return ('' in {'f': 2}) in {'has_key() is deprecated': True} class Example3(object): def __init__(self, bar): # Comments should have a space after the hash. if bar: bar += 1 bar = bar * bar return bar else: some_string = """ Indentation in multiline strings should not be touched. Only actual code should be reindented. """ return (sys.path, some_string) ``` -------------------------------- ### Disable autopep8 formatting for code blocks Source: https://pypi.org/project/autopep8/2.3.2 Use comments to toggle autopep8 formatting off and on for specific sections of code. ```python # autopep8: off [ [23, 23, 13, 43], [32, 34, 34, 34], [56, 34, 34, 11], [10, 10, 10, 10], ] # autopep8: on ``` === COMPLETE CONTENT === This response contains all available snippets from this library.
