Factorial and gamma functions in SciPy - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to calculate the factorial of 5 using scipy.

SciPy

from scipy.special import [1]
result = factorial(5)
print(result)

💡 Hint

Common Mistakes

Using 'gamma' instead of 'factorial' directly.

Trying to import from math instead of scipy.special.

The factorial function from scipy.special calculates the factorial of a number.

medium

Complete the code to calculate the gamma function value at 4.

SciPy

from scipy.special import [1]
result = gamma(4)
print(result)

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

💡 Hint

Common Mistakes

Using 'factorial' instead of 'gamma' for non-integer inputs.

Confusing 'beta' function with gamma.

The gamma function generalizes factorial to real and complex numbers. gamma(4) equals 3! = 6.

3fill in blank

hard

Fix the error in the code to correctly compute factorial of 7.

SciPy

from scipy.special import factorial
result = factorial([1])
print(result)

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

A'7'

Cfactorial

Dgamma

💡 Hint

Common Mistakes

Passing the number as a string like '7'.

Passing the function name instead of a number.

The factorial function expects an integer input, not a string. Use 7 without quotes.

4fill in blank

hard

Fill both blanks to create a dictionary of factorials for numbers 1 to 5.

SciPy

from scipy.special import factorial
factorials = {i: [1](i) for i in range(1, [2])}
print(factorials)

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

💡 Hint

Common Mistakes

Using gamma instead of factorial for this task.

Using 5 as range end, which excludes 5.

Use factorial function and range up to 6 to include 5.

5fill in blank

hard

Fill all three blanks to create a dictionary of gamma values for numbers 1 to 4.

SciPy

from scipy.special import gamma
values = [1]: [2](i) for i in range(1, [3])}
print(values)

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

💡 Hint

Common Mistakes

Using factorial instead of gamma.

Using 4 as range end, which excludes 4.

Use i as key, gamma function for values, and range end 5 to include 4.
