The RGB color model, named so because of the initials of the three additive primary colors, is an additive color model in which red, green and blue light are added to reproduce various colors.The RGB color model is used in representation and display of images in electronic systems, such as televisions and computers. It is based on human perception of colors. Other alternative representations of color model are:YIQ: Luminance, Chrominance (used by composite video signals)HLS: Hue, Luminance, SaturationHSV: Hue, Saturation, ValueThe colorsys module defines functions for conversion of color values between RGB color model and three other coordinate systems.

The –m option of command line option searches for a given module and execute it as the __main__ module. This mechanism is internally supported by runpy module from Python's standard module that allows scripts to be located using the Python module namespace rather than the filesystem.This module defines two functionsrun_module()This function executes the code of the specified module and return the resulting module globals dictionary.The mod_name argument should be an absolute module name. If the module name refers to a package rather than a normal module, then that package is imported and the __main__ submodule within that package is then ... Read More
The sndhdr module in Python's standard library provides utility functions that read the type of sound data which is in a file. The functions return a namedtuple(), containing five attributesfiletypestring representing 'aifc', 'aiff', 'au', 'hcom', 'sndr', 'sndt', 'voc', 'wav', '8svx', 'sb', 'ub', or 'ul'.frameratethe sampling_rate will be either the actual value or 0 if unknown or difficult to decode.nchannelsnumber of channels or 0 if it cannot be determined or if the value is difficult to decodenframeseither the number of frames or -1.sampwidthbits_per_sample, will either be the sample size in bits or 'A' for A-LAW or 'U' for u-LAW.functions in sndhdr ...

Configuration information of Python's installation can be accessed by the sysconfig module. For example the list of installation paths and the configuration variables specific to the installation platform.The sysconfig module provides the following functions to access Configuration variablessysconfig.get_config_vars()With no arguments, this function returns a dictionary of all configuration variables relevant for the current platform.>>> import sysconfig >>> sysconfig.get_config_vars() {'prefix': 'E:\python37', 'exec_prefix': 'E:\python37', 'py_version': '3.7.2', 'py_version_short': '3.7', 'py_version_nodot': '37', 'installed_base': 'E:\python37', 'base': 'E:\python37', 'installed_platbase': 'E:\python37', 'platbase': 'E:\python37', 'projectbase': 'E:\python37', 'abiflags': '', 'LIBDEST': 'E:\python37\Lib', 'BINLIBDEST': 'E:\python37\Lib', 'INCLUDEPY': 'E:\python37\Include', 'EXT_SUFFIX': '.pyd', 'EXE': '.exe', 'VERSION': '37', 'BINDIR': 'E:\python37', 'SO': '.pyd', 'userbase': 'C:\Users\acer\AppData\Roaming\Python', 'srcdir': 'E:\python37'}With ...

Indentation is an important feature of Python syntax. Code blocks in function, class or loops are required to follow same indent level for statements in it. The tabnanny module in Python's standard library is able to detect any violation in this stipulation.This module is primarily intended to be used in command line mode with –m switch. However, it can also be imported in an interpreter session.Command line usagepython –m tabnanny –q example.pyFor verbose output use –v switchpython –m tabnanny –v example.pyFollowing functions are defined in tabnanny module for checking indentation programmatically.check()This function checks for ambiguously indented lines in a given ...

The wave module in Python's standard library is an easy interface to the audio WAV format. The functions in this module can write audio data in raw format to a file like object and read the attributes of a WAV file.The file is opened in 'write' or read mode just as with built-in open() function, but with open() function in wave modulewave.open()This function opens a file to read/write audio data. The function needs two parameters - first the file name and second the mode. The mode can be 'wb' for writing audio data or 'rb' for reading.obj = wave.open('sound.wav', 'wb')A ... Read More
The winsound module is specific to Python installation on Windows operating system. The module defines following functions −Beep()When this function is called a beep is heard from the PC’s speaker. The function needs two parameters. The frequency parameter specifies frequency of the sound, and must be in the range 37 through 32, 767 hertz. The duration parameter specifies duration of sound in .>>> import winsound >>> winsound.Beep(1000, 500)MessageBeep()This function plays a sound as specified in the registry. The type argument specifies which sound to play. Possible values are −-1, MB_ICONASTERISK, MB_ICONEXCLAMATION, MB_ICONHAND, MB_ICONQUESTION, and MB_OK (default).The value -1 produces a ... Read More
