'utf-8' codec can't decode byte 0xe9 in position 4: unexpected end of data

问题

Im very new to this language and encountered some trouble to send emails through python, my code looks like this:

import smtplib
server=smtplib.SMTP("smtp.gmail.com",587)
server.starttls()
server.login('username','password')

message = "hi there"
server.sendmail('username', 'username', message)

server.quit()

my system is: Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:06:47) [MSC v.1914 32 bit (Intel)] on win32

and the output I get is:

Traceback (most recent call last):
File "C:\pythonfiles\testmail - kopia.py", line 6, in <module>
  server=smtplib.SMTP("smtp.gmail.com",587)
File "C:\python\lib\smtplib.py", line 261, in __init__
  fqdn = socket.getfqdn()
File "C:\python\lib\socket.py", line 676, in getfqdn
  hostname, aliases, ipaddrs = gethostbyaddr(name)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in 
position 4: unexpected end of data

My computername consists of the letter é can i have to do something with that? Ive saved the file through notepad to UTF-8.

Any ideas?

Cheers André

回答1:

utf-8 is probably not the right encoding. This is a current problem when parsing files etc including french writting (as I suppose is the case you mention)

I usually solve this problem by :

mystring = 'gdjéàếè'
new_string = mystring.encode('iso-8859-1')
