Instance method for converting int to str - str() and __str__()
I was wondering if there is any resource that explains why certain methods like str() and type() were implemented the way they are, rather than .to_string() or .type() instance/object methods. I find instance/object methods more intuitive for this cases, but I am wondering why it wasn't implemented it like that. I know there are equivalents like __str__() and __class__ , but passing object to str() or type() seems more popular. Any resources for reading or some background information would be helpful. - CS -- https://mail.python.org/mailman/listinfo/python-list
Re: sys path modification
Modules are installed, but they are in a different directory than standard modules directory. I considered an option to add a site specific directory, but I want to make module path application specific rather than installing it in system-wide directory. virtualenv is one option, but that means anyone who wants to run this particular script will need to activate virtualenv each time. I thought allowing application to find/use it's dependencies would be easier. Are there any other options?

sys path modification
I am trying to understand sys.path working and best practices for managing it within a program or script. Is it fine to modify sys.path using sys.path.insert(0, EXT_MODULES_DIR)? One stackoverflow answer - http://stackoverflow.com/a/10097543 - suggests that it may break external 3'rd party code as by convention first item of sys.path list, path[0], is the directory containing the script that was used to invoke the Python interpreter. So what are best practices to prepend sys.path in the program itself? Any further elaboration would be helpful. - thanks, N -- https://mail.python.org/mailman/listinfo/python-list

MIMEText encode error - Python 2.6.6
I am trying to write a program which can email file's content using
smtplib. I am getting following error while using Python 2.6.6
version.
{{{
File "./killed_jobs.py", line 88, in sendmail
msg = MIMEText(ipfile.read, 'plain')
File "/home/ssp/sge/python/2.6.6/lib/python2.6/email/mime/text.py",
line 30, in __init__
self.set_payload(_text, _charset)

line 224, in set_payload

line 73, in encode_7or8bit
orig.encode('ascii')
AttributeError: 'builtin_function_or_method' object has no attribute 'encode'
}}}
I am referring to email examples on the doc site
http://docs.python.org/release/2.6.6/library/email-examples.html#email-examples
. Following is the msg object part in my code:
{{{
...
...
def sendmail(inputfile):
ipfile = open(inputfile, 'r')
msg = MIMEText(ipfile.read, 'plain')
ipfile.close()
...
...
}}}
I have tried setting subtype and chartype separately as mentioned here
- http://docs.python.org/release/2.6.6/library/email.mime.html, but
the error remains same. Any help on what might be wrong here?
