Series sorting in Data Analysis Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to sort the Series in ascending order.

Data Analysis Python

import pandas as pd
s = pd.Series([3, 1, 2])
s_sorted = s.[1]()

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

💡 Hint

Common Mistakes

Using sort_index() which sorts by index, not values.

Using sorted() which returns a list, not a Series.

The sort_values() method sorts the Series by its values in ascending order.

medium

Complete the code to sort the Series in descending order.

Data Analysis Python

import pandas as pd
s = pd.Series([3, 1, 2])
s_sorted_desc = s.sort_values([1]=False)

💡 Hint

Common Mistakes

Using 'descending' which is not a valid parameter.

Using 'reverse' which is not a parameter for sort_values.

The ascending parameter controls the sort order. Setting it to True sorts ascending, False sorts descending.

3fill in blank

hard

Fix the error in the code to sort the Series by index.

Data Analysis Python

import pandas as pd
s = pd.Series([3, 1, 2], index=['b', 'a', 'c'])
s_sorted = s.[1]()

💡 Hint

Common Mistakes

Using sort_values() which sorts by values, not index.

Using sorted() which returns a list, not a Series.

The sort_index() method sorts the Series by its index labels.

4fill in blank

hard

Fill both blanks to create a dictionary of word lengths for words longer than 3 letters.

Data Analysis Python

words = ['apple', 'bat', 'carrot', 'dog']
lengths = {word: [1] for word in words if len(word) [2] 3}

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

Alen(word)

B>

C<

Dword

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<' instead of '>' which filters shorter words.

Using 'word' instead of 'len(word)' for the value.

We use len(word) to get the length, and filter words with length greater than 3 using >.

5fill in blank

hard

Fill all three blanks to create a dictionary with uppercase keys and values greater than 1.

Data Analysis Python

data = {'a': 1, 'b': 2, 'c': 3}
result = { [1]: [2] for k, v in data.items() if v [3] 1 }

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

Ak.upper()

Bv

C>

Dk

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'k' instead of 'k.upper()' for keys.

Using '<' instead of '>' for filtering values.

Keys are converted to uppercase with k.upper(). Values are kept as v. We filter values greater than 1 using >.
