Practice - 5 Tasks

1fill in blank

easy

Complete the code to import the SciPy library.

SciPy

import [1]

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

Apandas

Bmatplotlib

Cscipy

Dnumpy

Attempts:

3 left

💡 Hint

Common Mistakes

Importing numpy instead of scipy

Importing pandas or matplotlib which are for data and plotting

We import scipy because it provides scientific computing tools beyond basic Python.

2fill in blank

medium

Complete the code to use SciPy's function to calculate the integral of a function.

SciPy

from scipy import integrate
result = integrate.[1](lambda x: x**2, 0, 1)

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

Aderivative

Bquad

Coptimize

Dfft

Attempts:

3 left

💡 Hint

Common Mistakes

Using derivative which calculates derivatives, not integrals

Using optimize or fft which are unrelated here

The quad function calculates definite integrals in SciPy.

3fill in blank

hard

Fix the error in the code to import the linear algebra module from SciPy.

SciPy

from scipy import [1]
result = [1].inv([[1, 2], [3, 4]])

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

Asignal

Bstats

Coptimize

Dlinalg

Attempts:

3 left

💡 Hint

Common Mistakes

Importing stats or optimize which do not have matrix inversion

Using signal which is for signal processing

The linalg module in SciPy provides linear algebra functions like matrix inversion.

4fill in blank

hard

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

SciPy

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

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

Alen(word)

Blen(word) > 3

Cword.startswith('a')

Dword.upper()

Attempts:

3 left

💡 Hint

Common Mistakes

Using word.upper() as value which changes the word

Using word.startswith('a') as condition which filters differently

The dictionary maps each word to its length using len(word). The filter keeps words with length greater than 3 using len(word) > 3.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase words to their lengths if length is greater than 4.

SciPy

{ [1]: [2] for word in words if [3] }

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

Aword.upper()

Blen(word)

Clen(word) > 4

Dword.lower()

Attempts:

3 left

💡 Hint

Common Mistakes

Using word.lower() as keys which is lowercase

Using length condition less than or equal to 4

The keys are uppercase words using word.upper(). The values are lengths with len(word). The filter keeps words longer than 4 characters with len(word) > 4.
