5. History of Pyhton
Python was created by Guido van
Rossum in the late 1980s and released
in 1991, t was designed to be a simple,
readable, and versatile programming
language

6. Key Feature of Python
1) Open-source and free.
2) Cross-platform (Windows, macOS, Linux, Raspberry Pi)
3) Extensive standard library.

7. Python Vs C
} ..
Aspect Python C
Type High-level, interpreted
programming language.
Low-level, procedural
programming language.
Syntax Simple and easy to read, with
minimal boilerplate.
Strict and verbose, requiring
detailed code.
Execution Interpreted language (executed
via an interpreter).
Compiled language (requires a
compiler like GCC).
Speed Slow Faster

8. Application of Python
● Web Development: Django, Flask
● Data Science:Pandas, NumPy, Matplotlib
● Cybersecurity: Scripting, automation, and
penetration testing

11. Variables
In Python you don’t need to declare variables,
but you can specify data type to variable via
casting
X = 10
Y = “khressy”
Print(X)
Print(y)
Sample
...

12. Data Types
x = 10
x = 10.5
x = "Hello World"
Integer
Float
str
...

13. Data Types
x = [“BMW", “Audi", “Ford"]
x = (“BMW", “Audi", “Ford")
x = range(6)
List
tuple
range
...

14. Operators: Arithmetic
+ Addition
- subtraction
* Multiplcation
/ Division
% Modulus
** Exponentiation
// Floor Division
...

15. Operators: Logical
And &&
Or ||
Not !
...

16. List
Collection of item can be edited (order and changeable)
x = [“BMW", “Audi", “Ford"]
print(x)
Print(x[1])
...
x = [“BMW", “Audi", “Ford"]
X[0] = “Honda”
x = [“BMW", “Audi", “Ford"]
x.append(“Honda”)
x.remove(“Audi”)

17. tuple
Collection of immutable items can be (order and unchangeable)
x = (“BMW", “Audi", “Ford“)
print(x)
Print(x[1])
...
x = [“BMW", “Audi", “Ford"]
y = list(x)
y.remove(“BMW”)
x = tuple(y)

18. Conditions: if statement
...

i += 1
i = 0
while i < 6:

29. Library
...
There are a huge number of libraries
Such as
os
