Python Library
A library is a collection of modules. It is a reusable chunk of
code that you may want to include in your programs/projects.
Python offers a vast array of libraries to cater to different
needs, ranging from general programming to specialized fields
like data science, machine learning, web development, and
more. Below is a categorized overview:

Pandas
Numpy
Some python
libraries are:-

Numpy is considered as one of the most popular
machine learning library in Python. Array interface is
the best and the most important feature of Numpy. This
interface can be utilized for expressing images, sound
waves, and other binary raw streams as an array of real
numbers in N-dimensional.
Numpy

import numpy as np
arr = np.array([1, 2, 3, 4, 5])
print(arr)
print(type(arr))
Output- [1 2 3 4 5]
<class 'numpy.ndarray'>
Example 1-

import numpy as np
arr = np.array([[1, 2, 3], [4, 5, 6]])
print(arr)
Output- [[1 2 3]
[4 5 6]]
Example 2-

Pandas is a Python library used for working with data
sets. It has functions for analyzing, cleaning, exploring,
and manipulating data. Its allows us to analyze big
data and make conclusions based on statistical
theories. It can clean messy data sets, and make them
readable and relevant.
Data manipulation and analysis
Provides DataFrames for structured data operations.s
Pandas

import pandas as pd
data = {'Name':[' Janny ', 'Amit',’Suji‘]
'Age':[28,34,29,42]}
df = pd.DataFrame(data)
print df
Its output is as follows −
Age Name
0 28 Janny
1 34 Amit
2 29 Suji
Example1

pyttsx3 is a text-to-speech conversion library in Python.
Unlike alternative libraries, it works offline.
import pyttsx3
engine = pyttsx3.init()
engine.say("I will speak this text")
engine.runAndWait()
Pyttsx3

Wikipedia
Wikipedia is a Python library that makes it easy to
access and parse data from Wikipedia. Search
Wikipedia, get article summaries, get data like links
and images from a page, and more.

Example1
import wikipedia
# finding result for the search
# sentences = 2 refers to numbers of line
result = wikipedia.summary("India", sentences = 2)
# printing the result
print(result)

A python module can be defined as a python
program file which contains a python code
including python functions, class, or variables.
In other words, we can say that our python
code file saved with the extension (.py) is
treated as the module.
Python Modules

A Module is a file containing document
and statement
provide proper organization
code reusability
namespace management
encapsulation

Some Python Modules are:-
datetime
1
webbrowser
2
OS
3
Tkinter
4
random
5

General-Purpose Libraries
os: For interacting with the operating system (e.g., file handling, environment variables)
sys: Access system-specific parameters and functions
re: Regular expressions for pattern matching and text processing
datetime: For handling date and time
math: Provides mathematical functions like trigonometry, logarithms, etc
15

datetime
The datetime module supplies classes for
manipulating dates and times.
The datetime module has many methods to
return information about the date object.

import datetime
x = datetime.datetime.now()
print(x.year)
print(x.strftime("%A"))
Output-2021
Sunday
17
Example- Return the year and name of weekday

webbrowser
The webbrowser module includes functions to
open URLs in interactive browser applications.
The module includes a registry of available
browsers, in case multiple options are available
on the system. It can also be controlled with
the BROWSER environment variable.

Example-
import webbrowser
webbrowser.open('http://docs.python.org/lib/module-webbrowser.html')
To open a page in the browser, we use
open() function.

OS
The OS module in Python provides functions for
interacting with the operating system. OS comes
under Python’s standard utility modules. This
module provides a portable way of using
operating system-dependent functionality.

1. os.remove() - os.remove() method in Python is used
to remove or delete a file path. This method can
not remove or delete a directory.
2. os.mkdir() - os.mkdir() method in Python is used
to create a directory named path with the specified
numeric mode.
The *os* and *os.path* modules include many
functions to interact with the file system. Some
functions are-

3. os.listdir()- os.listdir() method in Python is
used to get the list of all files and directories
in the specified directory. If we don’t specify
any directory, then list of files and
directories in the current working directory
will be returned.

Tkinter
Tkinter is a graphical user interface (GUI)
module for Python, you can make desktop
apps with Python and can
develop GUI applications like calculator, login
system, text editor, etc.

Tkinter Widgets
Tkinter provides various controls, such as
buttons, labels and text boxes used in a GUI
application. These controls are commonly
called widgets.

Important method of Tkinter
This method is used to start the application. The mainloop()
function is an infinite loop which is used to run the
application, it will wait for an event to occur and process
the event as long as the window is not closed.
The mainloop() Function:-
This method is mainly used to create the main window.
Tk(screenName=None, baseName=None, className='Tk', useTk=1) :-

Random
The random module is a built-in module to
generate the pseudo random variables. It can
be used to perform some action randomly
such as to get a random number, selecting a
random elements from a list, shuffle elements
randomly, etc.

Method of Random
seed()- It initialize the random number generator.
getstate()- It returns the current internal state of
the random number generator.
setstate()- It restores the internal state of the
random number generator.

Method of Random
choices()- It returns a list with a element from the
given sequence.
randint()- It returns a random number between the
given range.
