โœ… Python basics for AI and data analysis

Python is the main language used to build AI models.

Why Python is used in AI
โ€ข Simple and readable
โ€ข Huge AI and data ecosystem
โ€ข Fast to experiment

How Python fits in AI workflow
โ€ข Load data
โ€ข Clean and transform data
โ€ข Train models
โ€ข Evaluate results

๐Ÿ† Core Python concepts you must know

Variables
Store values

Example
x = 10
name = "AI"

Data types
int โ†’ 10
float โ†’ 3.14
string โ†’ "data"
boolean โ†’ True or False

Lists
Ordered collection
Can store multiple values

Example
marks = [70, 80, 90]
Access marks[0] โ†’ 70

Tuples
Like lists but immutable
Example
shape = (100, 3)

Dictionaries
Key value pairs
Example
student = {"marks": 80, "age": 20}

Why dictionaries matter
โ€ข Store structured data
โ€ข Used in JSON, APIs

Control flow
If condition: Used for decisions

Example:
if score > 50:
print("Pass")

Loops
Repeat tasks

For loop
for i in range(5):
print(i)

Used for
Iterating over data
Running experiments

Functions
Reusable code blocks

Example
def average(a, b):
return (a + b) / 2

Why functions matter
โ€ข Cleaner code
โ€ข Modular logic

Libraries
Pre written code

Common AI libraries
โ€ข NumPy โ†’ Numerical computing, arrays, matrix operations
โ€ข Pandas โ†’ Data cleaning, transformation, and analysis
โ€ข SciPy โ†’ Scientific computing and advanced math functions

Python mindset for AI
โ€ข Think in data, not logic
โ€ข Use libraries, not raw loops
โ€ข Read error messages carefully

Python is the AI backbone. Basics are enough to start libraries do heavy lifting
