## Part 2: Practical Coding Challenges
### Challenge 1: Basic Python (Beginner)
```python
# Write a function that takes a list of numbers and returns:
# - The sum of all even numbers
# - The product of all odd numbers
# Example: [1, 2, 3, 4, 5] -> (6, 15)
def process_numbers(numbers):
# Your code here
pass
# Test
print(process_numbers([1, 2, 3, 4, 5])) # Should print: (6, 15)
```
**Can you solve this?** ☐ Yes ☐ No ☐ With hints
---
### Challenge 2: Data Structures (Beginner-Intermediate)
```python
# Write a function that takes a string and returns a dictionary
# with character counts, but only for characters that appear more than once
# Example: "hello" -> {'l': 2}
def count_duplicates(text):
# Your code here
pass
# Test
print(count_duplicates("hello")) # Should print: {'l': 2}
print(count_duplicates("programming")) # Should print: {'g': 2, 'r': 2, 'm': 2}
```
**Can you solve this?** ☐ Yes ☐ No ☐ With hints
---
### Challenge 3: OOP (Intermediate)
```python
# Create a BankAccount class with:
# - Private balance attribute
# - deposit() method
# - withdraw() method (check for sufficient funds)
# - get_balance() method
# - Transaction history tracking
class BankAccount:
# Your code here
pass
# Test
account = BankAccount(100)
account.deposit(50)
account.withdraw(30)
print(account.get_balance()) # Should print: 120
```
**Can you solve this?** ☐ Yes ☐ No ☐ With hints
---
### Challenge 4: Decorators (Advanced)
```python
# Create a decorator that measures function execution time
# and caches results for same arguments
def timing_cache(func):
# Your code here
pass
@timing_cache
def fibonacci(n):
if n < 2:
return n
return fibonacci(n-1) + fibonacci(n-2)
# Test
print(fibonacci(10)) # Should cache intermediate results
```
**Can you solve this?** ☐ Yes ☐ No ☐ With hints
---
### Challenge 5: Generators (Advanced)
```python
# Create a generator that yields prime numbers up to n
def prime_generator(n):
# Your code here
pass
# Test
primes = list(prime_generator(20))
print(primes) # Should print: [2, 3, 5, 7, 11, 13, 17, 19]
```
**Can you solve this?** ☐ Yes ☐ No ☐ With hints
---
### Challenge 6: Async Programming (Expert)
```python
# Write an async function that fetches multiple URLs concurrently
# and returns their content lengths
import asyncio
async def fetch_all_lengths(urls):
# Your code here
pass
# Test
urls = [
"https://example.com",
"https://python.org",
"https://github.com"
]
# Should fetch all URLs concurrently and return their lengths
```
**Can you solve this?** ☐ Yes ☐ No ☐ With hints
