First SciPy computation - Interactive Code Practice

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'

Ascipy

Bnumpy

Cpandas

Dmatplotlib

Attempts:

3 left

💡 Hint

Common Mistakes

Importing numpy instead of scipy

Forgetting to import the library

Using incorrect library names

We use import scipy to bring the SciPy library into our program.

2fill in blank

medium

Complete the code to calculate the mean of the array using SciPy.

SciPy

from scipy import stats

data = [1, 2, 3, 4, 5]
mean_value = stats.[1](data).mean

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

Amedian

Bdescribe

Cvariance

Dmode

Attempts:

3 left

💡 Hint

Common Mistakes

Using mode or median which do not return mean directly

Trying to call mean on a list

Using variance which returns variance, not mean

The describe function returns descriptive statistics including the mean.

3fill in blank

hard

Fix the error in the code to compute the Euclidean distance between two points using SciPy.

SciPy

from scipy.spatial import distance

point1 = (1, 2)
point2 = (4, 6)
dist = distance.[1](point1, point2)

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

Ahamming

Bcosine

Cmanhattan

Deuclidean

Attempts:

3 left

💡 Hint

Common Mistakes

Using cosine which measures angle similarity

Using manhattan which sums absolute differences

Using hamming which counts differing bits

The euclidean function computes the straight-line distance between two points.

4fill in blank

hard

Fill both blanks to create a dictionary of word lengths for words longer than 3 characters.

SciPy

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

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

Alen(word)

B>

C<

Dword

Attempts:

3 left

💡 Hint

Common Mistakes

Using word instead of len(word) for value

Using less than instead of greater than in condition

Not filtering words by length

We use len(word) to get the length and filter words with length greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary of uppercase words and their lengths for words longer than 3 characters.

SciPy

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

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

Aw.upper()

Blen(w)

C>

Dw.lower()

Attempts:

3 left

💡 Hint

Common Mistakes

Using lowercase instead of uppercase for keys

Not filtering words by length

Using word instead of length for values

The dictionary keys are uppercase words using w.upper(), values are lengths, and we filter words longer than 3.
