Hello all,
First let me appologise if this has been answered but I could not find
an acurate answer to this interesting problem.
If the following is true:
C:\Python25\rg.py>python
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32
bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more
information.
>>> [] == []
True
>>> ['-o'] == []
False
>>> ['-o'] == False
False
>>>
Then why do I get the following results:
C:\Python25\rg.py>help.py -o
print arg ['-o']
type(arg): <type 'list'>
arg is True? False
help.py version 1.0 Copyright RDEG (c) 2007
['-o'] is an unrecognized option.
Progam Exit (0)
<python>
import sys
_ver_ = 1.00
if '-h' in sys.argv or '--help' in sys.argv:
print
print " help.py Version", _ver_, "Copyright RDEG (c) 2007"
print '''
Options : -h, --help -- display this message
Progam Exit (0)'''
sys.exit(0)
else:
arg = sys.argv[1:]
print 'print arg', arg
print 'type(arg):', type(arg)
print 'arg is True?', arg == True
print " help.py version", _ver_, "Copyright RDEG (c) 2007"
print " ", arg, "is an unrecognized option."
print " Progam Exit (0)"
sys.exit(0)
</python>
