*1. Introduction*
Python is a high-level, interpreted programming language known for its simplicity, readability, and versatility.
*2. Setting Up Python*
Download and install Python from the official website: (link unavailable)
*3. Basic Syntax*
```
# Comments start with the "#" symbol
print("Hello, World!") # Print to the console
# Indentation denotes code blocks
if True:
print("This is inside the if block")
```
*4. Variables*
Assign values to variables using the "=" operator.
```
x = 5 # Integer
y = "Hello" # String
```
*5. Data Types*
1. Integers (int): 1, 2, 3
2. Floats (float): 3.14, -0.5
3. Strings (str): "Hello", 'Hello'
4. Boolean (bool): True, False
5. Lists (list): [1, 2, 3], ["a", "b", "c"]
6. Tuples (tuple): (1, 2, 3), ("a", "b", "c")
7. Dictionaries (dict): {"name": "John", "age": 30}
*6. Operators*
1. Arithmetic: +, -, *, /, %
2. Comparison: ==, !=, <, >, <=, >=
3. Logical: and, or, not
4. Assignment: =, +=, -=, *=, /=, %=
*7. Control Structures*
1. If-Else Statements
```
x = 5
if x > 10:
print("x is greater than 10")
else:
print("x is less than or equal to 10")
```
1. For Loops
```
fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
print(fruit)
```
1. While Loops
```
i = 0
while i < 5:
print(i)
i += 1
```
*8. Functions*
Define functions using the "def" keyword.
```
def greet(name):
print("Hello, " + name + "!")
greet("John")
```
*9. Modules*
Import modules using the "import" statement.
```
import math
print(math.pi)
```
*10. File Input/Output*
Read and write files using the "open" function.
```
with open("example.txt", "w") as f:
f.write("Hello, World!")
with open("example.txt", "r") as f:
print(f.read())
```
*11. Object-Oriented Programming*
Define classes using the "class" keyword.
```
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
def greet(self):
print("Hello, my name is " + self.name + "!")
person = Person("John", 30)
person.greet()
```
*12. Advanced Topics*
1. Regular Expressions
2. Web Development (Flask, Django)
3. Data Analysis (Pandas, NumPy)
4. Machine Learning (Scikit-learn, TensorFlow)
This tutorial covers the basics of Python programming. Practice and explore more advanced topics to become proficient.
