Question

in linux, I opened terminal and input python2.7 and then input the codes as follows:

>>> s = u'\u0561'
>>> print s
ա
>>> len(s)
1

the length of u’\u0561′ is only 1? Why?I learned that every non-alphabet character’s length is 2~4 byte in unicode, why does it use only 1 byte? and i test other unicode characters, i found that almost all the unicode character’s length is 1, why?

Answer 1

The len function doesn’t count the number of bytes – it count the number of items in any sequence (in this case, the number of characters in the string).
