Numpy recarray.any() function | Python

In numpy, arrays may have a data-types containing fields, analogous to columns in a spreadsheet. An example is [(a, int), (b, float)], where each entry in the array is a pair of (int, float). Normally, these attributes are accessed using dictionary lookups such as arr['a'] and arr['b'].
Record arrays allow the fields to be accessed as members of the array, using arr.a and arr.b. numpy.recarray.any() function returns True if any elements in record array evaluate to True.

Syntax : numpy.recarray.any(axis=None, out=None, keepdims=False)

Parameters:
axis : [ None or int or tuple of ints, optional] Axis or axes along which a logical OR operation is performed.
out : [ndarray, optional] A location into which the result is stored.
  -> If provided, it must have a shape that the inputs broadcast to.
  -> If not provided or None, a freshly-allocated array is returned.
keepdims : [ bool, optional] If this is set to True, the axes which are reduced are left in the result as dimensions with size one. With this option, the result will broadcast correctly against the input array.
If the default value is passed, then keepdims will not be passed through to any method of sub-classes of ndarray, however, any non-default value will be. If the sub-classes sum method does not implement keepdims any exceptions will be raised.

Returns : [ndarray, bool] It returns True if any elements evaluate to True.

Code #1 :

# Python program explaining
# numpy.recarray.any() method

# importing numpy as geek
import numpy as geek

# creating input array with 2 different field
in_arr = geek.array([(5.0, 2), (3.0, 4)],
       dtype =[('a', float), ('b', int)])
print ("Input array : ", in_arr)

# convert it to a record array, using arr.view(np.recarray)
rec_arr = in_arr.view(geek.recarray)
print("Record array of float: ", rec_arr.a)

# applying recarray.any methods to float record array
out_arr = geek.recarray.any(rec_arr.a)
print ("Output array: ", out_arr)

print("\nRecord array of int: ", rec_arr.b)
# applying recarray.any methods
# to int record array
out_arr = geek.recarray.any(rec_arr.b)
print ("Output array: ", out_arr)

Output:

Input array :  [(5.0, 2) (3.0, 4)]
Record array of float:  [ 5.  3.]
Output array:  True

Record array of int:  [2 4]
Output array:  True

Code #2 :

If we apply numpy.recarray.any() to whole record array then it will give Type error because the array is flexible or mixed type.

# Python program explaining
# numpy.recarray.any() method

# importing numpy as geek
import numpy as geek

# creating input array with 2 different field
in_arr = geek.array([(5.0, 2), (3.0, 4)],
         dtype =[('a', float), ('b', int)])
print ("Input array : ", in_arr)

# convert it to a record array,
# using arr.view(np.recarray)
rec_arr = in_arr.view(geek.recarray)
print("Record array ", rec_arr)

# applying recarray.any methods to  record array
out_arr = geek.recarray.any(rec_arr)
print ("Output array: ", out_arr)

Output:

TypeError: cannot perform reduce with flexible type
