np.linspace() for evenly spaced arrays in NumPy - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create an array of 5 numbers evenly spaced between 0 and 10.

NumPy

import numpy as np
arr = np.linspace(0, 10, [1])
print(arr)

💡 Hint

Common Mistakes

Using 10 instead of 5 creates more points than needed.

Forgetting the third argument defaults to 50 points.

The third argument in np.linspace() specifies how many numbers to generate. Here, 5 numbers between 0 and 10 are created.

medium

Complete the code to create 4 numbers evenly spaced between 1 and 2.

NumPy

import numpy as np
arr = np.linspace(1, [1], 4)
print(arr)

💡 Hint

Common Mistakes

Using 3 or 4 as the end value changes the range incorrectly.

Confusing the number of points with the end value.

The second argument is the end value. Here, 4 numbers between 1 and 2 are created.

Fix the error in the code to generate 6 numbers from 0 to 5.

NumPy

import numpy as np
arr = np.linspace(0, 5, [1])
print(arr)

💡 Hint

Common Mistakes

Using 5 generates only five numbers, missing one point.

Using 7 generates too many points.

The third argument must be 6 to get six numbers including both 0 and 5.

4fill in blank

hard

Fill both blanks to create an array of 7 numbers from 10 to 20.

NumPy

import numpy as np
arr = np.linspace([1], [2], 7)
print(arr)

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

💡 Hint

Common Mistakes

Swapping start and end values.

Using 15 or 25 changes the range incorrectly.

The first blank is the start (10), the second blank is the end (20), and 7 numbers are generated between them.

5fill in blank

hard

Fill all three blanks to create a dictionary with keys as numbers from 1 to 5 and values as their squares using np.linspace().

NumPy

import numpy as np
numbers = np.linspace([1], [2], [3])
squares = {int(num): int(num)**2 for num in numbers}
print(squares)

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

💡 Hint

Common Mistakes

Using 10 as the end value changes the range incorrectly.

Using fewer or more than 5 points changes the keys.

The numbers start at 1, end at 5, and there are 5 points to get integers 1 to 5. The dictionary comprehension creates squares.
