💡 Hint

Common Mistakes

Using the wrong variable name that is not assigned by enumerate.

Forgetting that enumerate returns two values.

The enumerate function returns pairs of (index, value). The first variable should be the index, commonly named i.

Complete the code to start enumerate counting from 1 instead of 0.

Python

for idx, color in enumerate(colors, [1]):
    print(f"{idx}: {color}")

💡 Hint

Common Mistakes

Passing 0 which is the default and does not change the start.

Passing a negative number which is unusual for indexing.

The second argument to enumerate sets the starting index. Using 1 starts counting from 1.

Fix the error in the code to correctly unpack the values from enumerate.

Python

items = ['pen', 'pencil', 'eraser']
for [1] in enumerate(items):
    print(f"{index}: {item}")

💡 Hint

Common Mistakes

Using only one variable to unpack two values.

Using variable names that don't match in the print statement.

enumerate returns two values per loop: the index and the item. You must unpack both.

4fill in blank

Fill both blanks to create a dictionary with index as key and item as value using enumerate.

Python

items = ['a', 'b', 'c']
indexed = [1](items)
result = {idx: [2] for idx, val in indexed}

💡 Hint

Common Mistakes

Using list instead of enumerate.

Using the index as the dictionary value instead of the item.

Use enumerate to get index and value pairs. Then use the value val as dictionary values.

5fill in blank

hard

Fill all three blanks to create a list of strings showing index and item using enumerate.

Python

words = ['dog', 'cat', 'bird']
result = [f"[1]: [2]" for [3], word in enumerate(words)]

💡 Hint

Common Mistakes

Using different variable names inconsistently.

Using the wrong variable for index or item.

The variable i is the index from enumerate, and word is the item. Use i and word in the formatted string and for loop.
