Is python available in kali linux?

python-dev-is-python3

Starting with the Debian 11 [bullseye] and Ubuntu 20.04 LTS [focal] releases, all python packages use explicit python3 or python2 interpreter and do not use unversioned /usr/bin/python-config at all. Some third-party code is now predominantly python3 based, yet may use /usr/bin/python-config.

This is a convenience package which ships a symlink to point /usr/bin/python-config script at the current default python3. It may improve compatibility with other modern systems, whilst breaking some obsolete or 3rd-party software.

No packages may declare dependencies on this package.

The Python debugger

[email protected]:~# pdb -h
usage: pdb.py [-c command] ... [-m module | pyfile] [arg] ...

Debug the Python program given by pyfile. Alternatively,
an executable module or package to debug can be specified using
the -m switch.

Initial commands are read from .pdbrc files in your home directory
and in the current directory, if they exist.  Commands supplied with
-c are executed after commands from .pdbrc files.

To let the script run until an exception occurs, use "-c continue".
To let the script run up to a given line X in the debugged file, use
"-c 'until X'".

The Python documentation tool

[email protected]:~# pydoc -h
pydoc - the Python documentation tool

pydoc  ...
    Show text documentation on something.   may be the name of a
    Python keyword, topic, function, module, or package, or a dotted
    reference to a class or function within a module or module in a
    package.  If  contains a '/', it is used as the path to a
    Python source file to document. If name is 'keywords', 'topics',
    or 'modules', a listing of these things is displayed.

pydoc -k 
    Search for a keyword in the synopsis lines of all available modules.

pydoc -n 
    Start an HTTP server with the given hostname [default: localhost].

pydoc -p 
    Start an HTTP server on the given port on the local machine.  Port
    number 0 can be used to get an arbitrary unused port.

pydoc -b
    Start an HTTP server on an arbitrary unused port and open a web browser
    to interactively browse documentation.  This option can be used in
    combination with -n and/or -p.

pydoc -w  ...
    Write out the HTML documentation for a module to a file in the current
    directory.  If  contains a '/', it is treated as a filename; if
    it names a directory, documentation is written for all the contents.

An interpreted, interactive, object-oriented programming language

[email protected]:~# python -h
usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Options and arguments [and corresponding environment variables]:
-b     : issue warnings about str[bytes_instance], str[bytearray_instance]
         and comparing bytes/bytearray with str. [-bb: issue errors]
-B     : don't write .pyc files on import; also PYTHONDONTWRITEBYTECODE=x
-c cmd : program passed in as string [terminates option list]
-d     : turn on parser debugging output [for experts only, only works on
         debug builds]; also PYTHONDEBUG=x
-E     : ignore PYTHON* environment variables [such as PYTHONPATH]
-h     : print this help message and exit [also -? or --help]
-i     : inspect interactively after running script; forces a prompt even
         if stdin does not appear to be a terminal; also PYTHONINSPECT=x
-I     : isolate Python from the user's environment [implies -E and -s]
-m mod : run library module as a script [terminates option list]
-O     : remove assert and __debug__-dependent statements; add .opt-1 before
         .pyc extension; also PYTHONOPTIMIZE=x
-OO    : do -O changes and also discard docstrings; add .opt-2 before
         .pyc extension
-q     : don't print version and copyright messages on interactive startup
-s     : don't add user site directory to sys.path; also PYTHONNOUSERSITE
-S     : don't imply 'import site' on initialization
-u     : force the stdout and stderr streams to be unbuffered;
         this option has no effect on stdin; also PYTHONUNBUFFERED=x
-v     : verbose [trace import statements]; also PYTHONVERBOSE=x
         can be supplied multiple times to increase verbosity
-V     : print the Python version number and exit [also --version]
         when given twice, print more information about the build
-W arg : warning control; arg is action:message:category:module:lineno
         also PYTHONWARNINGS=arg
-x     : skip first line of source, allowing use of non-Unix forms of #!cmd
-X opt : set implementation-specific option. The following options are available:
         -X faulthandler: enable faulthandler
         -X showrefcount: output the total reference count and number of used
             memory blocks when the program finishes or after each statement in the
             interactive interpreter. This only works on debug builds
         -X tracemalloc: start tracing Python memory allocations using the
             tracemalloc module. By default, only the most recent frame is stored in a
             traceback of a trace. Use -X tracemalloc=NFRAME to start tracing with a
             traceback limit of NFRAME frames
         -X importtime: show how long each import takes. It shows module name,
             cumulative time [including nested imports] and self time [excluding
             nested imports]. Note that its output may be broken in multi-threaded
             application. Typical usage is python3 -X importtime -c 'import asyncio'
         -X dev: enable CPython's "development mode", introducing additional runtime
             checks which are too expensive to be enabled by default. Effect of the
             developer mode:
                * Add default warning filter, as -W default
                * Install debug hooks on memory allocators: see the PyMem_SetupDebugHooks[]
                  C function
                * Enable the faulthandler module to dump the Python traceback on a crash
                * Enable asyncio debug mode
                * Set the dev_mode attribute of sys.flags to True
                * io.IOBase destructor logs close[] exceptions
         -X utf8: enable UTF-8 mode for operating system interfaces, overriding the default
             locale-aware mode. -X utf8=0 explicitly disables UTF-8 mode [even when it would
             otherwise activate automatically]
         -X pycache_prefix=PATH: enable writing .pyc files to a parallel tree rooted at the
             given directory instead of to the code tree
         -X warn_default_encoding: enable opt-in EncodingWarning for 'encoding=None'
--check-hash-based-pycs always|default|never:
    control how Python invalidates hash-based .pyc files
file   : program read from script file
-      : program read from stdin [default; interactive mode if a tty]
arg ...: arguments passed to program in sys.argv[1:]

Other environment variables:
PYTHONSTARTUP: file executed on interactive startup [no default]
PYTHONPATH   : ':'-separated list of directories prefixed to the
               default module search path.  The result is sys.path.
PYTHONHOME   : alternate  directory [or :].
               The default module search path uses /lib/pythonX.X.
PYTHONPLATLIBDIR : override sys.platlibdir.
PYTHONCASEOK : ignore case in 'import' statements [Windows].
PYTHONUTF8: if set to 1, enable the UTF-8 mode.
PYTHONIOENCODING: Encoding[:errors] used for stdin/stdout/stderr.
PYTHONFAULTHANDLER: dump the Python traceback on fatal errors.
PYTHONHASHSEED: if this variable is set to 'random', a random value is used
   to seed the hashes of str and bytes objects.  It can also be set to an
   integer in the range [0,4294967295] to get hash values with a
   predictable seed.
PYTHONMALLOC: set the Python memory allocators and/or install debug hooks
   on Python memory allocators. Use PYTHONMALLOC=debug to install debug
   hooks.
PYTHONCOERCECLOCALE: if this variable is set to 0, it disables the locale
   coercion behavior. Use PYTHONCOERCECLOCALE=warn to request display of
   locale coercion and locale compatibility warnings on stderr.
PYTHONBREAKPOINT: if this variable is set to 0, it disables the default
   debugger. It can be set to the callable of your debugger of choice.
PYTHONDEVMODE: enable the development mode.
PYTHONPYCACHEPREFIX: root directory for bytecode cache [pyc] files.
PYTHONWARNDEFAULTENCODING: enable opt-in EncodingWarning for 'encoding=None'.
