Mathematical constants (pi, e, golden ratio) in SciPy - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to import the constant pi from scipy.

SciPy

💡 Hint

Common Mistakes

Importing 'e' instead of 'pi'.

Using 'golden' which is the golden ratio, not pi.

The constant pi is imported from scipy.constants to use the value of π.

medium

Complete the code to print the value of the mathematical constant e from scipy.

SciPy

from scipy.constants import [1]
print(e)

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

💡 Hint

Common Mistakes

Confusing 'pi' with 'e'.

Using 'golden' which is the golden ratio, not e.

The constant e is the base of natural logarithms and is imported from scipy.constants.

3fill in blank

hard

Fix the error in the code to correctly import and print the golden ratio constant from scipy.

SciPy

from scipy.constants import [1]
print(golden)

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

💡 Hint

Common Mistakes

Using 'golden_ratio' which is not defined in scipy.constants.

Trying to import 'phi' which is not the correct name.

The golden ratio constant is named golden in scipy.constants. Using golden imports it correctly.

4fill in blank

hard

Fill both blanks to create a dictionary with keys 'pi' and 'e' and their values from scipy.constants.

SciPy

constants = {'pi': [1], 'e': [2]
print(constants)

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

💡 Hint

Common Mistakes

Using approximate float values instead of constants.

Mixing up keys and values.

Use the constants pi and e imported from scipy.constants to assign their exact values in the dictionary.

5fill in blank

hard

Fill all three blanks to create a dictionary with keys 'pi', 'e', and 'golden' and their values from scipy.constants.

SciPy

constants = {'pi': [1], 'e': [2], 'golden': [3]
print(constants)

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

💡 Hint

Common Mistakes

Using 'phi' instead of 'golden'.

Using approximate numbers instead of constants.

Use the constants pi, e, and golden from scipy.constants to fill the dictionary values correctly.
