Beginner Code Example

Here is a simple, well-commented code example that works correctly.

# A beginner friendly example of For Loops
def basic_example():
    # Print a welcome message
    print("Welcome to For Loops")
    # Calculate a simple sum
    result = 10 + 20
    return result

basic_example()

Intermediate Code Example

Real-world use case for For Loops:

# Intermediate usage
import datetime

class RealWorldCase:
    def __init__(self, name):
        self.name = name
        self.timestamp = datetime.datetime.now()

    def process(self):
        print(f"Processing {self.name} at {self.timestamp}")
        return [i * 2 for i in range(5)]

case = RealWorldCase("For Loops")
case.process()

Advanced Code Example

Production pattern, edge cases, optimization:

# Advanced usage pattern
import functools
import logging

logging.basicConfig(level=logging.INFO)

def advanced_wrapper(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        logging.info(f"Executing advanced pattern for For Loops")
        try:
            return func(*args, **kwargs)
        except Exception as e:
            logging.error(f"Error in execution: {e}")
            raise
    return wrapper

@advanced_wrapper

Common Mistakes

Here are 3-5 mistakes beginners make, with wrong code and correct fix.

1. Ignoring variable scope Wrong Code:

   def wrong():
       print(x)
   x = 10
   

   Correct Fix:

   x = 10
   def right():
       print(x)
   

2. Mutable default arguments Wrong Code:

   def append_to(num, target=[]):
       target.append(num)
       return target
   

   Correct Fix:

   def append_to(num, target=None):
       if target is None:
           target = []
       target.append(num)
       return target
   

3. Not handling exceptions properly Wrong Code:

   try:
       1 / 0
   except:
       pass
   

   Correct Fix:

   try:
       1 / 0
   except ZeroDivisionError:
       print("Cannot divide by zero")
