[FIXED] unsupported format string passed to numpy.ndarray

Issue

Let's say I have the array:

import numpy as np
x = np.array([1.2334, 2.3455, 3.456], dtype=np.float32)

and want to print:

print('{:.2f}%'.format(x))

It gives me:

unsupported format string passed to numpy.ndarray.__format__

Solution

If you still want format

list(map('{:.2f}%'.format,x))
Out[189]: ['1.23%', '2.35%', '3.46%']
