For data analysis, Exploratory Data Analysis (EDA) must be your first step. Exploratory Data Analysis helps us to −To give insight into a data set.Understand the underlying structure.Extract important parameters and relationships that hold between them.Test underlying assumptions.Understanding EDA using sample Data setTo understand EDA using python, we can take the sample data either directly from any website or from your local disk. I’m taking the sample data from the UCI Machine Learning Repository which is publicly available of a red variant of Wine Quality data set and try to grab much insight into the data set using EDA.import pandas ...

There are multiple ways by which we can add packages to our existing anaconda environment.Method 1 − One common approach is to use the “Anaconda Navigator” to add packages to our anaconda environment. Once “Ananconda Navigator” is opened, home page will look something like −Go to Environments tab just below the Home tab and from there we can check what all packages are installed and what is not.It is very easy to install any package through anaconda navigator, simply search the required package, select package and click on apply to install it. Let's suppose tensorflow packages are not installed in ... Read More

There are numerous ways you can draw geographical coordinates on Google Maps. However, in case you want to save it in a local file, one better way to accomplish is through a python module called gmplot.Python library gmplot allows us to plot data on google maps. gmplot has a matplotlib-like interface to generate the HTML and javascript to deliver all the additional data on top of Google Maps.InstallationIt is easy to install gmplot using pip incase gmplot is not already installed −pip install gmplotOn running above command, you may see output something like −From above, we can see the latest ...

Tkinter is a python library for developing GUI (Graphical User Interfaces). We use the tkinter library for creating an application of UI (User Interface), to create windows and all other graphical user interfaces.If you’re using python 3.x(which is recommended), Tkinter will come with Python as a standard package, so we don’t need to install anything to use it.Before creating a registration form in Tkinter, let’s first create a simple GUI application in Tkinter.Creating a simple GUI applicationBelow is the program to create a window by just importing Tkinter and set its title −from tkinter import * from tkinter import ttk ...

First thing comes in my mind, why to compare these two language only? This may be because both are interpreted, agile languages with an object oriented philosophy and very huge communities support. However, though both languages share some ideas, syntax elements and have almost the same features the two communities have nothing in common.Both the languages are very popular among the developer’s community (This is also one of the reasons to compare). Below are the top ten most popular languages in 2018 on GitHub based on opened pull request −Top 10 most popular languages on GitHub based on opened pull ... Read More

SimPy (rhymes with “Blimpie”) is a python package for process-oriented discrete-event simulation.InstallationThe easiest way to install SimPy is via pip:pip install simpyAnd the output you may get will be something like, At the time of writing, simpy-3.0.11 is the most recent version of SimPy, and we will use it for all the below examples.In case, SimPy is already installed, use the –U option for pip to upgrade.pip install –U simpyNote: You need to have python 2.7 or above version and for Linux/Unix/MacOS you may need root privileges to install SimPy.To check if SimPy was successfully installed, open a python shell ...

The ModuleFinder class in 'modulefinder' module can determine set of modules imported by a certain script. This module has a command line interface as well as programmatic interface.For demonstration of functionality, use following script#modfinder.py import hello try: import trianglebrowser import nomodule, mymodule except ImportError: passCommand line interfaceFollowing command displays list of modules located as well as not found.E:\python37>python -m modulefinder modfinder.pyOutputName File ---- ---- m __main__ modfinder.py m hello hello.py m math m trianglebrowser trianglebrowser.py Missing modules: ? mymodule imported from __main__ ? nomodule imported from __main__Programmatic interfaceModuleFinder class in ...

Automatic garbage collection is one of the important features of Python. Garbage collector mechanism attempts to reclaim memory occupied by objects that are no longer in use by the program.Python uses reference counting mechanism for garbage collection. Python interpreter keeps count of number of times an object is referenced by other objects. When references to an object are removed, the count for an object is decremented. When the reference count becomes zero, the object memory is reclaimed.Normally this mechanism is performed automatically. However, it can be done on purpose if a certain situation arises in the program. The 'gc' module ... Read More

Warning is different from error in a program. If error is encountered, Python program terminates instantly. Warning on the other hand is not fatal. It displays certain message but program continues. Warnings are issued to alert the user of certain conditions which aren't exactly exceptions. Typically warning appears if some deprecated usage of certain programming element like keyword/function/class etc. is found.Warning messages are displayed by warn() function defined in 'warning' module of Python's standard library. Warning is actually a subclass of Exception in built-in class hierarchy. There are a number of built-in Warning subclasses. User defined subclass can also be ... Read More

Provisions of the struct module in the Python library are useful in performing conversions between C type structs and Python bytes objects. This can be achieved by module level functions as well as Struct class and its methods as defined in the struct module.The conversion functions use a format string. The byte order, size, and alignment used in the format string is determined by formatting character as per the following tableCharacterByte orderSizeAlignment@nativenativenative=nativestandardnonebig-endianstandardnone!network (= big-endian)standardnoneFollowing table shows format characters used to denote C type variables and corresponding Python types.FormatC TypePython typexpad byteno valueccharbytes of length 1b/Bsigned/unsigned charinteger?_Boolboolh/Hshort/unsigned shortintegeri/Iint/unsigned intintegerl/Llong/unsigned longintegerffloatfloatddoublefloatschar[]bytespchar[]bytesPvoid *integerFollowing ...
