Python: Find the available built-in modules

Python Basic: Exercise-78 with Solution

Write a Python program to find the available built-in modules.

Sample Solution-1:

Python Code:

import sys
import textwrap
module_name = ', '.join(sorted(sys.builtin_module_names))
print(textwrap.fill(module_name, width=70))

Sample Output:

_ast, _bisect, _codecs, _collections, _datetime, _elementtree,                                                
_functools, _heapq, _imp, _io, _locale, _md5, _operator, _pickle,                                             
_posixsubprocess, _random, _sha1, _sha256, _sha512, _signal, _socket,                                         
_sre, _stat, _string, _struct, _symtable, _thread, _tracemalloc,                                              
_warnings, _weakref, array, atexit, binascii, builtins, errno,                                                
faulthandler, fcntl, gc, grp, itertools, marshal, math, posix, pwd,                                           
pyexpat, select, spwd, sys, syslog, time, unicodedata, xxsubtype,                                             
zipimport, zlib 

Sample Solution-2:

Python Code:

 help('modules')

Sample Output:

Please wait a moment while I gather a list of all available modules...

/usr/local/lib/python3.6/dist-packages/bokeh/util/deprecation.py:34: BokehDeprecationWarning: 
The bokeh.charts API has moved to a separate 'bkcharts' package.

This compatibility shim will remain until Bokeh 1.0 is released.
After that, if you want to use this API you will have to install
the bkcharts package explicitly.

/usr/local/lib/python3.6/dist-packages/bokeh/util/deprecation.py:34: BokehDeprecationWarning: MPL compatibility can no longer be successfully maintained, and is now deprecated. All MPL compat functions will be removed completely on the release of Bokeh 1.0. See http://bokeh.pydata.org/en/latest/docs/releases/0.12.5.html for more information
