Sometimes, we want to find all the factors of a number in Python.
In this article, we’ll look at how to find all the factors of a number in Python.
How to find all the factors of a number in Python?
To find all the factors of a number in Python, we can use the reduce function.
For instance, we write
from functools import reduce
def factors(n):
return set(reduce(list.__add__,
([i, n//i] for i in range(1, int(n**0.5) + 1) if n % i == 0)))
to define the factor function that returns the factors by looping from 1 to int(n**0.5) + 1 with a for loop.
And we put the values n that’s evenly divisible by i with
n % i == 0
And we use list.__add__ to add the factors into a list.
Finally, we call set to convert the returned list without the duplicate values by converting the list to a set.
Conclusion
To find all the factors of a number in Python, we can use the reduce function.
