Python Tip: Using enumerate() for index and value in loops
"""

### Description
print("Hello AI! This is my first AI script.\n")

# In several Python examples within the project, loops manually track indexes using counters.
# Python provides a built-in function `enumerate()` that simplifies this pattern and improves readability.
# Example list
items = ['apple', 'banana', 'cherry']

### Current pattern
print("Without enumerate():")
for i in range(len(items)):
print(i, items[i])

items = ['apple', 'banana', 'cherry']
print("\n Using enumerate():")
for index, item in enumerate(items):
print(index, item)

print("\n Using enumerate() starting from 1:")
for index, item in enumerate(items, start=1):
print(index, item)

for i, item in enumerate(items):
print(i, item)
# enumerate() makes code cleaner and more readable
