This is my array:
import numpy as np
boo = np.array([
[10, 55, 12],
[0, 81, 33],
[92, 11, 3]
])
If I print:
[[10 55 12]
[ 0 81 33]
[92 11 3]]
How to sort array column by ascending and row by descending like this:
[[33 81 92]
[10 12 55]
[0 3 11]]
# import the necessary packages.
import numpy as np
# create the array.
boo = np.array([
[10, 55, 12],
[0, 81, 33],
[92, 11, 3]
])
# we use numpy's 'sort' method to conduct the sorting process.
# we first sort the array along the rows.
boo = np.sort(boo, axis=0)
# we print to observe results.
print(boo)
# we therafter sort the resultant array again, this time on the axis of 1/columns.
boo = np.sort(boo, axis=1)
# we thereafter reverse the contents of the array.
print(boo[::-1])
# output shows as follows:
array([[33, 81, 92],
[10, 12, 55],
[ 0, 3, 11]])
