simple question: $1, $2 in py ?

[es_uomikim]

Hi,

I have one small simple question, that I didn't found answer in
google's. It's kind of begginers question because I'm a one. ; )

I wanned to ask how to use scripts with vars on input like this:

$ echo "something" | ./my_script.py

or:

$ ./my_scripy.py var1 var2


As far as I understand there's no $1, $2... etc stuff right ?

Sorry for a silly question.

Yes - but there is sys.argv

Try this


import this

print sys.argv


and invoke it as script with args. Make also sure to checkout modules
optparse and getopt to deal with the options.

Also try the OptParse module.

http://www.python.org/doc/2.4/lib/module-optparse.html

It handles the GNU/POSIX syntax very well.

Others answered about commandline args... You can also read
from stdin to get the piped input:



# pi.py
import sys
i = sys.stdin.read()
print "Your input: ", i

echo "something" | python pi.py

Your input: something

$ echo "something" | ./my_script.py

echo "test" | python -c "import sys; print sys.stdin.readlines()"

Yes - but there is sys.argv

Try this


import this

print sys.argv

I believe this last line should be:

print this.__builtins__['__import__']('sys').argv
