What's Python?
Python is a broadly-used, interpreted, object-orientated, and high-stage programming language with dynamic semantics, used for general-purpose programming. It became created by Guido van Rossum, and primary launched on February 20, 1991.
while you can know the python as a huge snake, the name of the Python programming language comes from an antique BBC television comedy sketch collection referred to as Monty Python’s Flying Circus.
one of the awesome features of Python is the truth that it is surely one individual’s paintings. commonly, new programming languages are advanced and published through big businesses employing lots of professionals, and because of copyright policies, it's far very hard to call any of the people involved in the venture. 

Learn Python: Tutorials for novices, Intermediate, and advanced Programmers

As you realize, computers absolutely depend on software code to characteristic nicely. there are so many programming languages available that facilitates developers create applications. Python is one of the excessive-stage, interpreted and widespread-motive programming languages that is straightforward to use, complete and effective. In 1991, Guido van Rossum (cited its father) evolved the Python programming language.

Dating from 1991, the Python programming language became taken into consideration a gap-filler, a way to put in writing scripts that “automate the uninteresting stuff” (as one popular ebook on gaining knowledge of Python positioned it) or to unexpectedly prototype programs so as to be implemented in different languages. however, during the last few years, Python has emerged as a 7339ff1fc90882f8f31ca1efdd2ac191 citizen in modern-day software program development, infrastructure management, and records evaluation. it's far not a lower back-room software language, however a main pressure in web application creation and systems control, and a key driving force of the explosion in high-quality="hide">big="hide">big|huge|massive|large="tipsBox"> information analytics and machine intelligence.
Python’s key blessings
Python’s success revolves around numerous benefits it gives for novices and specialists alike.
Python is simple to research and use
The range of capabilities in the language itself is discreet, requiring distinctly little funding of time or attempt to produce your first programs. The Python syntax is designed to be readable and easy. This simplicity makes Python an ideal teaching language, and it shall we learners choose it up speedy. As a end result, builders spend extra time thinking about the problem they’re looking to clear up and less time considering language complexities or interpreting code left via others.
Python is broadly followed and supported

Python is a famous general-cause programming language that may be used for a huge form of packages. It consists of excessive-level statistics systems, dynamic typing, dynamic binding, and plenty of extra functions that make it as useful for complicated utility development as it is for scripting or "glue code" that connects components together. it may also be prolonged to make system calls to almost all operating structures and to run code written in C or C++. because of its ubiquity and capability to run on almost every device structure, Python is a conventional language determined in a diffusion of different packages. The examine python app allows to improve primary standards by means of reading classes and by way of practicing in the compiler. you can enhance your python coding talents on the go with our app. The research Python Offline app is assisting college students, freshers, working professionals to discover ways to code in python and help to come to be prepared for the activity. This app is designed with the aid of the great python coders who have the enjoy of running with python & other programming languages. They selected questions regularly requested by using the interviewer to the candidate and really quickly are presenting ideal answers which helps you to get a activity.

Exercise 25

Write a program that asks the user to enter a word and return the opposite. Example if the user enters the word

python

, the program returns

nohtyp

.

Solution

# Ask user to enter a some string s
s = input("Enter a some string s : ")
# initializing reverse of the string s 
reverse = ""

# Building the string s in a reversed way
for x in s:
    reverse = x + reverse
print("The reverse of the string: ", s , " is : " , reverse)

Exercise 19

Write a Python algorithm that lists the strings that make up the list

l = ["laptop", "iphone", "tablet", "printer", "Ipad"]

by indicating the length of each string.

Solution

l = ["laptop", "iphone", "tablet", "printer", "Ipad"]
#browse through all items in the list l
for x in l:
    print(x, " is in list l, its length is: ", len(x))

Exercises 18

Write a program in Python that asks the user to enter a string s and return a message indicating whether the string contains the letter 'a' by indicating its position on the string. Example if the user types the string

s = 'language'

the program returns: The letter

'a'

is in position: 1 The letter

'a'

is in position: 5

Solution

# Ask user to enter a string s
s = input("Type a some string s : ")

# retrieve the len of the string s
n = len(s)

# Browsing through all characters of the string s
for i in range(0,n):
    # Try if the browsed character is equal to character 'a'
    if(s[i] == 'a'):
        print("The letter 'a' is at position : ", i , " in the string s")
