Numpy's isnumeric(~) method checks whether each string of the input array is numeric. Unlike the methods isdigit(~) and isdecimal(~), isnumeric(~) also extends to other languages.
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.isnumeric(["2.5", "", "3", "0", "五"])
array([False, False, True, True, True])
Here, note the following:
"2.5", which does represent a number, returned False."五", which means a 5 in Chinese/Japanese, returned True.
