Does array.array only hold real numbers?

Question

from array import array
x=array('f',('hi','hello'))
print(x)

#output=TypeError: must be real number,not str.

Answer 1

This is also allowed. It is a sample out of the official python documentation:

from array import array

array('l')
array('u', 'hello \u2641')
array('l', [1, 2, 3, 4, 5])
array('d', [1.0, 2.0, 3.14])
