根据先前获得最高值的数组创建新数组

Question

I have an array in Jupyter. I want to create two new arrays, one with the top 30% of values from the original array and one with the bottom 30% of values from the original array. Please help!

Answer 1

In Python you do it like this:

X = [1,2,3,4,5,6,7,8,9,10]
len_pct = int(len(X) * 0.3)

first, last = X[0:len_pct], X[len(X)-len_pct:len(X)]

print(first); # [1,2,3]
print(last); # [8,9,10]
