Simpson's rule (simpson) in SciPy - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to import the Simpson's rule function from scipy.integrate.

SciPy

from scipy.integrate import [1]

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

💡 Hint

Common Mistakes

Importing trapz instead of simpson.

Using quad which is for adaptive quadrature, not Simpson's rule.

The simpson function is imported from scipy.integrate to perform numerical integration using Simpson's rule.

2fill in blank

medium

Complete the code to calculate the integral of y over x using Simpson's rule.

SciPy

result = simpson(y, [1])

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

Caxis

Dx

💡 Hint

Common Mistakes

Passing dx instead of x array.

Using axis which is a keyword argument, not positional here.

The second argument to simpson is the x values over which y is sampled.

3fill in blank

hard

Fix the error in the code to correctly compute the integral with simpson when y is a 2D array along axis 0.

SciPy

integral = simpson(y, x, axis=[1])

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

B-1

C0

D2

💡 Hint

Common Mistakes

Using axis=1 which integrates along columns instead.

Using axis=-1 which is last axis, not axis 0.

When y is 2D and integration is along axis 0, axis=0 must be specified.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps each word to its length only if the length is greater than 3.

SciPy

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

Attempts:

3 left

💡 Hint

Common Mistakes

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

Using word > 3 which compares string to int.

The dictionary comprehension maps word to its length (len(word)) and filters words with length > 3.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase words to their values only if the value is positive.

SciPy

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

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

Ak.upper()

Bv

Ck, v

Ditem

💡 Hint

Common Mistakes

Using item instead of k, v in the loop.

Not converting keys to uppercase.

The comprehension maps uppercase keys (k.upper()) to values (v) for key-value pairs (k, v) where value is positive.
