Chapter 1: Introduction to Python Programming
This guide serves as a friendly introduction to the fundamental principles and features of Python programming, tailored for beginners.
Python is a versatile, high-level programming language that is interpreted and dynamic, making it suitable for various applications, including web development, enterprise solutions, and 3D CAD systems. Its rapid development and debugging capabilities stem from the absence of a compilation step, which significantly accelerates the edit-test-debug process.
Notably, Python boasts a vibrant community and numerous open-source projects, enhancing its accessibility and support. Being open-source, it's free to use, making it a popular choice across various industries. Additionally, Python is enriched with a wide range of third-party libraries that facilitate tasks in web development, data analysis, and scientific computing.
The PYPL Popularity of Programming Language Index highlights that Python is currently the most sought-after language worldwide, having seen a growth of 2.6% over the past five years, while Java experienced a decline of 5.3%. For a deeper understanding, refer to the latest data [here](source).
As a crucial tool for aspiring data scientists, mastering Python requires hands-on experience. Therefore, this guide presents 100 practical Python projects along with source codes, designed to help beginners apply their knowledge effectively. These projects are instrumental in solidifying learning and boosting confidence in Python programming.
Through this guide, you will not only enhance your skills but also create specific applications that can distinguish you in the job market. Let’s embark on this exciting journey into Python programming!

Section 1.1: Python Interview Preparation
To excel in your coding interviews, familiarize yourself with common Python interview questions. Here are some crucial ones to study:
Q&A 1: Function Example
def func(a):
a += 10
return a
def main():
x = 5
y = func(x)
x += y
print(x)
main() # Output: 20
Q&A 2: Dictionary Creation
my_dic = {"a": 1, "b": 2, "c": 3}
Q&A 3: String Manipulation
my_string = "Python is fun!"
result = my_string[-6:-1] + my_string[-2] + my_string[-8]
print(result) # Output: s funn
Q&A 4: Sum of a List
list_a = [1, 2, 4, 5]
def find_sum(data):
return sum(data)
print(find_sum(list_a)) # Output: 12
