Question

in a script I use sys.stdout.write() to output processed data to stdout, which later I use on CLI to redirect stdout to file:

python.exe script.py > file.out

I could not write to file inside python script as redirected file can’t be known

My problem is that I use also raw_input(), as I need user to pass certain number before processing starts, but prompt doesn’t show as I redirect stdout – i.e. script waits for user input but does not show anything

Can someone give me a tip how to handle this?

TIA

Answer 1

Take the filename as a command-line argument instead of redirecting stdout. That way, you can print output or use raw_input() as normal. Example:

import sys

outfile = open(sys.argv[1], 'w')
# write to the outfile
x = raw_input("What's your name?")
outfile.write(x)

Usage:

python myscript.py file.out

This will work on any platform.
