if age >= 18:
print("Adult")
elif age > 13:
print("Teen")
else:
print("Child")
8. Loops
For Loop
for i in range(5):
print(i)
While Loop
i = 0
while i < 5:
print(i)
i += 1
9. Functions
def greet(name):
return f"Hello, {name}"
print(greet("Anurag"))
10. Lists
fruits = ["apple", "banana", "cherry"]
fruits.append("mango")
print(fruits[1])
11. Tuples
point = (10, 20)
print(point[0])
12. Dictionaries
student = {"name": "Anurag", "age": 21}
print(student["name"])
13. Sets
nums = {1, 2, 3, 2}
print(nums) # No duplicates
14. String Methods
s = "hello"
print(s.upper())
print(s.replace("l", "x"))
15. List Comprehension
squares = [x*x for x in range(10)]
16. Exception Handling
try:
x = 10 / 0
except ZeroDivisionError:
print("Cannot divide by zero")
finally:
print("Done")
17. Classes and Objects
class Person:
def __init__(self, name):
self.name = name
def greet(self):
print("Hi", self.name)
p = Person("Anurag")
p.greet()
18. File Handling
with open("file.txt", "r") as file:
print(file.read())
with open("file.txt", "w") as file:
file.write("Hello World")
19. Modules and Packages
import math
print(math.sqrt(16))
Custom module:
# mymodule.py
def add(a, b):
return a + b
# main.py
from mymodule import add
20. Useful Libraries
-
numpy: Numerical computing -
pandas: Data analysis -
matplotlib: Plotting -
flask: Web development -
requests: HTTP requests
21. Virtual Environments
python -m venv env
source env/bin/activate # or env\Scripts\activate on Windows
22. Decorators
def decorator(func):
def wrapper():
print("Before")
func()
print("After")
return wrapper
@decorator
def hello():
print("Hello!")
hello()
23. Generators
def gen():
yield 1
yield 2
for x in gen():
print(x)
24. Lambda Functions
square = lambda x: x * x
print(square(5))
25. Working with APIs
import requests
response = requests.get("https://api.github.com")
print(response.json())
