*Python Cheatsheet* 🐍

This Cheatsheet covers the core Python concepts everyone should know.

*1. Basics*

print() – Outputs text to the screen.

Comments – Use # for single-line and triple quotes """ for multi-line comments.

print("Hello") # This will print Hello


*2. Variables & Data Types*

Variables store values of different types like numbers, strings, booleans, lists, etc.


x = 10 # Integer
name = "Alice" # String
flag = True # Boolean


*3. Conditionals*

Used to make decisions in code using if, elif, and else.

if x > 0:
print("Positive")
else:
print("Not positive")


*4. Loops*

- For loop: Iterates over a sequence.

- While loop: Repeats as long as a condition is true.

for i in range(3):
print(i)


*5. Functions*

A reusable block of code defined with def.

def greet(name):
return "Hello " + name


*6. Lists & List Comprehension*

- Lists: Store multiple items in one variable.

- List comprehension: Short way to create lists.

nums = [1, 2, 3]
squares = [x**2 for x in nums]


*7. Dictionaries*

Key-value pairs, like a mini-database.

user = {"name": "Bob", "age": 25}
print(user["name"])


*8. String Methods*

Strings are text, and Python provides handy methods to manipulate them.

s = "hello"
print(s.upper()) # "HELLO"
print(s.replace("e", "a")) # "hallo"

*9. File Handling*

Read and write files using open().

with open("file.txt", "w") as f:
f.write("Hi there!")

*10. Error Handling*

Prevents your program from crashing with try, except, and finally.


try:
x = 10 / 0
except:
print("Error occurred")


*11. Classes & Objects*

Used in Object-Oriented Programming to create reusable code structures.

class Dog:
def init(self, name):
self.name = name


*12. Useful Built-in Functions*

Handy tools built into Python.

len(), type(), sum(), min(), max(), sorted()
