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'

Cpandas

Dmatplotlib

💡 Hint

Common Mistakes

Importing numpy instead of scipy

Importing pandas or matplotlib which are different libraries

We import scipy to use its scientific computing tools.

2fill in blank

medium

Complete the code to use SciPy's integration function.

SciPy

from scipy import [1]

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

Aoptimize

Bintegrate

Cstats

Dcluster

💡 Hint

Common Mistakes

Using optimize instead of integrate

Using stats or cluster which serve different purposes

The integrate module in SciPy helps calculate integrals.

3fill in blank

hard

Fix the error in the code to calculate the integral of sin(x) from 0 to pi.

SciPy

import numpy as np
from scipy import integrate
result, error = integrate.quad(np.[1], 0, np.pi)
print(result)

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

Asin

Bcos

Ctan

Dlog

Attempts:

💡 Hint

Common Mistakes

Using cosine or tangent instead of sine

Using logarithm which is unrelated here

The function to integrate is sin, so we use np.sin.

4fill in blank

hard

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

SciPy

words = ['data', 'science', 'is', 'fun']
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.startswith('s')

Dword.isalpha()

Attempts:

3 left

💡 Hint

Common Mistakes

Using word itself instead of its length

Using unrelated conditions like startswith or isalpha

We map each word to its length using len(word) and filter words with length greater than 3.

5fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps uppercase words to their lengths if length is greater than 2.

SciPy

words = ['AI', 'ML', 'DATA', 'SCIENCE']
result = {word.[1](): [2] for word in words if len(word) > 2}

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

A{

Bupper

Clen(word)

D[

💡 Hint

Common Mistakes

Using list brackets instead of dictionary braces

Using lowercase method instead of upper

Using word instead of its length for values

The dictionary starts with {, words are converted to uppercase with upper(), and values are word lengths.
