[issue7399] Possible bug in Python Tutorial

2009-11-26 Thread David Henretty 

New submission from David Henretty dhenre...@a2etech.com:

Hi,

In the v3.1.1 Python Tutorial (section 10.7 - Internet Access), the 
sample code (shown below) results in the following error :-

from urllib.request import urlopen
for line in urlopen('http://tycho.usno.navy.mil/cgi-bin/timer.pl'):
 if 'EST' in line or 'EDT' in line:
 print(line)

Traceback (most recent call last):
  File stdin, line 2, in module
TypeError: Type str doesn't support the buffer API

I presume this has something to do with the assumed type of the 
variable 'line', but I am very new to Python.

Replacing the 'if' line with the following DOES work :-

 if 'EST' in str(line) or 'EDT' in str(line):

Can anyone confirm / explain this ?

Thanks,

DH

R. David Murray rdmur...@bitdance.com added the comment:

The example is indeed wrong.  urlopen is returning an object that emits
binary data.  The error comes from using 'in' on incompatible types. 
The solution is to encode the data with an appropriate encoding, once
you figure out what that is.
