Python is a high-level, interpreted programming language that is widely used for web development, scientific computing, data analysis, artificial intelligence, and more. Here is a crash course on Python:

Data Types

Python has several built-in data types, including:

Integers: whole numbers
Floats: numbers with decimals
Strings: text surrounded by quotes
Booleans: True or False

Variables

Variables are used to store values. In Python, you can assign a value to a variable using the equals sign (=). Example:

python

x = 5

Operators

Python has several types of operators, including:

Arithmetic operators (+, -, *, /, %, **)
Comparison operators (==, !=, <, >, <=, >=)
Logical operators (and, or, not)
Assignment operators (=, +=, -=, *=, /=, %=, **=)

Control Flow

Python has several control flow statements, including:

If statements: execute code if a condition is True

python

if x > 0:

print("x is positive")

For loops: iterate over a sequence of values

python

for i in range(5):

print(i)

While loops: execute code while a condition is True

python

i = 0

while i < 5:

print(i)

i += 1

Functions

Functions are used to encapsulate code into reusable blocks. In Python, you can define a function using the def keyword.

python

def add_numbers(x, y):

return x + y

Libraries

Python has many built-in libraries that provide useful functionality, and you can also install third-party libraries using tools like pip. Here are a few examples:

math: provides math functions like sqrt() and sin()
random: provides functions for generating random numbers
pandas: provides data analysis tools
numpy: provides numerical computing tools

This is a crash course on Python! There’s a lot more to learn, but this should give you a good starting point, enroll today and jump start your skills.
