Numpy's isdecimal(~) method checks whether each string of the input array is a decimal character.

WARNING

Numbers with dots do not qualify as numeric

For instance, "2" qualifies as a digit, but "2.5" with a dot does not.

Parameters

1. a | array-like

The input array.

Return value

If a is a scalar, then a single boolean is returned. Otherwise, a Numpy array of booleans is returned.

Examples

np.char.isdecimal(["2.5", "", "3", "0"],)
array([False, False, True, True])

Notice how "2.5", which does represent a number, returned False.
