np.split() for dividing arrays in NumPy - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to split the array into 3 equal parts.

NumPy

import numpy as np
arr = np.array([1, 2, 3, 4, 5, 6])
splits = np.split(arr, [1])

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

💡 Hint

Common Mistakes

Using the length of the array instead of the number of splits.

Using a number that does not divide the array length evenly.

We want to split the array into 3 equal parts, so the second argument to np.split should be 3.

2fill in blank

medium

Complete the code to split the array at the specified indices.

NumPy

import numpy as np
arr = np.array([10, 20, 30, 40, 50])
splits = np.split(arr, [1])

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

A[0, 2]

B[1, 3]

C[2, 4]

D[3, 5]

💡 Hint

Common Mistakes

Using indices that are out of range.

Confusing the indices with the number of splits.

The array will be split at indices 1 and 3, creating subarrays: [10], [20, 30], and [40, 50].

3fill in blank

hard

Fix the error in the code to split the array into 4 parts.

NumPy

import numpy as np
arr = np.array([1, 2, 3, 4, 5, 6, 7, 8])
splits = np.split(arr, [1])

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

A[2, 4, 6]

C[1, 3, 5]

💡 Hint

Common Mistakes

Passing the number 4 instead of indices for unequal splits.

Using indices that do not split the array evenly.

To split into 4 parts, we provide indices where to split: [2, 4, 6].

4fill in blank

hard

Fill both blanks to create a dictionary with words as keys and their lengths as values, only for words longer than 3 letters.

NumPy

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

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

Aword

Blen(word)

Cword.upper()

Dlen(word) - 1

💡 Hint

Common Mistakes

Using the length as the key instead of the word.

Using incorrect expressions for length.

The dictionary keys are the words themselves, and the values are their lengths.

5fill in blank

hard

Fill all three blanks to create a dictionary with uppercase words as keys and their lengths as values, only for words longer than 3 letters.

NumPy

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

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

Aword.upper()

Blen(word)

Clen(word) > 3

Dword.lower()

💡 Hint

Common Mistakes

Using lowercase instead of uppercase for keys.

Not filtering words by length.

Keys are uppercase words, values are lengths, and condition filters words longer than 3 letters.
