Chapter 1 An Introduction to Python

 What are the advantages of Python?

Readability and Simplicity: Python code is easy to read and write, making it accessible for beginners and reducing the cost of program maintenance.

Versatility: Python is a versatile language that can be used for web development, data science, artificial intelligence, machine learning, automation, and more.

Large Standard Library: Python comes with a vast standard library that includes modules and packages for a wide range of tasks, eliminating the need for additional downloads.

Object-Oriented Language: Python supports both procedural and object-oriented programming, promoting code reuse and modular design.

 Python is a scripting language. Comment.

Python's concise syntax, ease of use, and the ability to interact with other languages and systems make it well-suited for scripting tasks.

- What is dry run in Python?
A dry run in Python refers to the process of mentally or manually simulating the execution of code without actually running it on a computer. It helps developers understand the flow of the program, identify potential errors, and verify the logic before executing the code.

- Write a short note on datatypes in Python.

Python supports various data types, including:

Numeric Types: Integers, Floats, Complex Numbers

Sequence Types: Strings, Lists, Tuples

Mapping Type: Dictionary

Boolean Type: bool

What is the output of following code :

 def f(X) :

 def  f1(a, b) :

 print ("hello")

 if (b==0) :

   print ("NO")

   return

 return f(a, b)

 return f1

 @ f

 def f(a, b) :

 return a%b

 f(4, 0)

 X = 5

 def  f1( ):

 global X

 X = 4

 f2(a, b) :

 global X

 return a+b+X

f1()

 total = f2(1, 2)

 print (total)

- Define identifiers.
