💡 Hint

Common Mistakes

Using 3 rows instead of 2.

Confusing rows and columns.

The plt.subplots function takes the number of rows and columns. To create a 2x2 grid, we need 2 rows and 2 columns.

Complete the code to plot data on the first subplot in a 2x2 grid.

Matplotlib

fig, axes = plt.subplots(2, 2)
axes[[1], 0].plot([1, 2, 3], [4, 5, 6])
plt.show()

💡 Hint

Common Mistakes

Using 1 instead of 0 for the first subplot.

Using an index out of range.

Subplots are indexed starting at 0. The first subplot is at index 0.

Fix the error in the code to create a facet grid with 3 rows and 1 column.

Matplotlib

fig, axes = plt.subplots([1], 1)
axes[0].plot([1, 2, 3], [3, 2, 1])
plt.show()

💡 Hint

Common Mistakes

Setting rows to 1 instead of 3.

Confusing rows and columns.

To create 3 rows and 1 column, the first argument to plt.subplots should be 3.

Fill both blanks to create a dictionary comprehension that maps words to their lengths only if length is greater than 3.

Matplotlib

lengths = {word: [1] for word in words if [2]

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

Alen(word)

Blen(word) > 3

Cword

Dword > 3

💡 Hint

Common Mistakes

Using the word itself instead of its length.

Using the word in the condition instead of its length.

The dictionary comprehension maps each word to its length using len(word). The condition filters words with length greater than 3 using len(word) > 3.

Fill all three blanks to create a dictionary comprehension that maps uppercase words to their counts if count is greater than 0.

Matplotlib

result = { [1]: [2] for [3], [2] in data.items() if [2] > 0}

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

💡 Hint

Common Mistakes

Using 'item' instead of 'k' and 'v'.

Not converting keys to uppercase.

Using the wrong variable names.

The comprehension maps the uppercase key k.upper() to its value v for each key-value pair k, v in data.items() where the value is greater than 0.
