Dear all,
I have to change some lines from a template file, which is rather long
to paste here, but I would like to make some parts of some lines
optional with my command line arguments but I could not see this
directly, I can count the line numbers and decide on this basis to
decide the lines to be configured to my will.
More specifically, say, I have a that file includes
this is an example python file to play around
.

.
some lines
.

. -> an option line for example.
.
.
.
-> another option line so on.
and execute the script
./myScript option1 option2
so that the options at correct locations will be written.
Any other options for this simple job that i can improve my Python a
bit as well.
Best,

Your description is not explicit enough to convey your intention. If
your template file is too long to post, post a short representative
section, an input data sample and a hand-edited sample of the output
data you want to generate. You will get more and better advice. .

===================================================
Assuming the total number of changes is not large,
put OPTION1 where you want it to go in the text
put OPTION2 (same)
import sys
if len(sys.argv) >1:
OPTION1 = sys.argv[1]
else:
OPTION1 = "some default stuff"
similar for OPTION2
if len(sys.argv) >2:
like above
and any others
print section1+OPTION1+section2+OPTION2....
or
just using the line count (in place of "print sect..")
line_number= 0
for i in template:
if line_number matches line number to place Opt1
print OPTION1
elif line_number matches v2
print OPTION2
and so forth
else:
print i (line from template NOT being changed)
line_number += Line_number
you can group line number and replacement on command line
runprogram (43,"use this instead") (56,....
and parse inside program before opening template
one thing to watch out for:
for i in file... often returns just one character at a time,
meaning you will have to track EOL's yourself OR
import the readline and use it to stand a better chance of getting what
you expect from a read file function.
