Hello all.
This is a newly question. But I wish to understand why the below code is
providing different results.
import os, sys
if len(sys.argv) > 2:
filenames = sys.argv[1:]
else
print ("no parameters provided\n")
sys.edit()
for filename in filenames:
print ("filename is: %s\n" %filename)
The above code will return results like:
filename is test.txt
If I modify the above script slightly as shown below, I get a completely
different result.
if len(sys.argv) > 2:
filenames = sys.argv[1]
else
print ("no parameters provided\n")
sys.exit()
for filename in filenames:
print ("filename is: %s\n" % filename)
The result is the filename is spelled out a character at a time. The bit I am
missing is something to do with splicing or referencing in Python.
Why am I getting different results? In other languages I would have got the
whole content of the element when using the index of the array (list).

filename is: t
filename
As you've already had answers I'd like to point out that your test for
len(sys.argv) is wrong, else is missing a colon and sys.edit() is very
unlikely to work :)
