Practice - 5 Tasks

1fill in blank

easy

Pandas

import pandas as pd

s = pd.Series([1])
print(s)

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

A{10, 20, 30}

B[10, 20, 30]

C(10, 20, 30)

D'10, 20, 30'

💡 Hint

Common Mistakes

Using curly braces {} which create a set, not a list.

Using parentheses () which create a tuple, not a list.

Passing a string instead of a list.

The pd.Series function takes a list to create a Series. Lists are enclosed in square brackets [].

medium

Complete the code to create a Series with custom labels (index).

Pandas

import pandas as pd

s = pd.Series([1, 2, 3], index=[1])
print(s)

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

A[0, 1, 2]

B(1, 2, 3)

C['a', 'b', 'c']

D{'a', 'b', 'c'}

💡 Hint

Common Mistakes

Using a tuple or set instead of a list for the index.

Using numbers instead of strings for labels when strings are expected.

The index parameter expects a list of labels. Use square brackets with strings like ['a', 'b', 'c'].

3fill in blank

hard

Fix the error in the code to access the value with label 'b' from the Series.

Pandas

import pandas as pd

s = pd.Series([10, 20, 30], index=['a', 'b', 'c'])
value = s[[1]]
print(value)

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

A'b'

B"b"

💡 Hint

Common Mistakes

Using the label without quotes causing a NameError.

Using the position index instead of the label.

To access a value by label, use the label as a string inside quotes: s['b'].

4fill in blank

hard

Fill both blanks to create a Series from a dictionary and print its index labels.

Pandas

import pandas as pd

data = [1]
s = pd.Series(data)
print(s.[2])

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

A{'x': 100, 'y': 200, 'z': 300}

B[100, 200, 300]

💡 Hint

Common Mistakes

Using a list instead of a dictionary for data.

Using keys instead of index to get labels.

A Series can be created from a dictionary. The index attribute shows the labels.

5fill in blank

hard

Fill all three blanks to create a Series with custom labels, access a value by label, and print the values as a list.

Pandas

import pandas as pd

s = pd.Series([1], index=[2])
value = s[[3]]
print(list(s.values))

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

A[5, 10, 15]

B['one', 'two', 'three']

C'two'

D['a', 'b', 'c']

Attempts:

💡 Hint

Common Mistakes

Mismatching lengths of values and index.

Accessing by position instead of label.

Not converting values to a list before printing.

Create the Series with values and labels, access the value by label 'two', and print all values as a list.
