The exact version is 2.7.6 (2.7.6 (default, Jun 22 2015, 17:58:13) [GCC
4.8.2])
The behaviour is replicable even after OS restarts. As you've noticed the
print statement gets executed and pushes the typing command into a
new-line, this behaviour is not replicable when the file is imported as a
module or run the terminal.
I have tried figuring out what was happening by using the inspect module to
see who calls the function __len__ with some radically big context but I
can't seem to interpret the output myself (bit too deep in pythons belly
for my level). Code is shown bellow:
import inspect
class Errors:
def __init__(self):
pass
def toFile(self):
pass
def __len__(self):
curframe = inspect.currentframe()
calframe = inspect.getouterframes(curframe, context=15)
for i in range(15):
print " caller: ",calframe[i][3]
print "len is called"
return 0
What I get as output now:
>>> len(e)
caller: __len__
caller: <module>
caller: runcode
caller: main
caller: <module>
len is called
0
>>> caller: __len__
caller: get_arg_text
caller: fetch_tip
caller: get_the_calltip
caller: localcall
caller: pollresponse
caller: _getresponse
caller: getresponse
caller: handle
caller: __init__
caller: __init__
caller: finish_request
caller: process_request
caller: _handle_request_noblock
caller: handle_request
caller: manage_socket
caller: run
caller: __bootstrap_inner
caller: __bootstrap
len is called
e.toFile(
Maybe that can help? I know it doesn't really, it would be better to print
the class that owns the methods called, however I don't know how to do
that, so here's at least the file names:
>>> len(e)
caller: /home/dino/Desktop/bitbucket/refactor/errors/errors.py
caller: <pyshell#9>
caller: /usr/lib/python2.7/idlelib/run.py
caller: /usr/lib/python2.7/idlelib/run.py
caller: <string>
len is called
0
>>> caller: /home/dino/Desktop/bitbucket/refactor/errors/errors.py
caller: /usr/lib/python2.7/idlelib/CallTips.py
caller: /usr/lib/python2.7/idlelib/CallTips.py
caller: /usr/lib/python2.7/idlelib/run.py
caller: /usr/lib/python2.7/idlelib/rpc.py
caller: /usr/lib/python2.7/idlelib/rpc.py
caller: /usr/lib/python2.7/idlelib/rpc.py
caller: /usr/lib/python2.7/idlelib/rpc.py
caller: /usr/lib/python2.7/idlelib/run.py
caller: /usr/lib/python2.7/SocketServer.py
caller: /usr/lib/python2.7/idlelib/rpc.py
caller: /usr/lib/python2.7/SocketServer.py
caller: /usr/lib/python2.7/SocketServer.py
caller: /usr/lib/python2.7/SocketServer.py
caller: /usr/lib/python2.7/SocketServer.py
caller: /usr/lib/python2.7/idlelib/run.py
caller: /usr/lib/python2.7/threading.py
caller: /usr/lib/python2.7/threading.py
caller: /usr/lib/python2.7/threading.py
len is called
e.toFile(
Thanks for the help,
Dino
