Python - 'ascii' codec can't decode byte

I'm really confused. I tried to encode but the error said

can't decode...
. What is Python doing under the hood?

>>> "你好".encode("utf8")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 0: ordinal not in range(128)

Answer Source

encode converts a unicode object to a string object. But here you have invoked it on a string object (because you don't have the u). So python has to convert the string to a unicode object first. So it does the equivalent of


But the decode fails because the string isn't valid ascii. That's why you get a complaint about not being able to decode.
