💡 Hint

Common Mistakes

Using tail(10) which shows the last 10 rows.

Using non-existent methods like show() or preview().

To preview the first 10 rows, use head(10). The other options are incorrect or invalid.

4fill in blank

hard

Fill all three blanks to create a dictionary showing the first 4 rows with their index and a column named 'score'.

💡 Hint

Common Mistakes

Using tail() instead of head().

Using j or other variable names instead of i.

Not converting index to list.

We convert the index to a list with tolist(), use head() to get first rows, and iterate with i.

5fill in blank

hard

Fill all three blanks to create a dictionary of the last 3 rows with their index and 'age' column values.

Pandas

result = {df.[2]().index.[1]()[[3]]: df.[2]()['age'][[3]] for [3] in range(-3, 0)}

Drag options to blanks, or click blank then click option'
