Hello I am trying to pipe the input from a data file as command line input using power shell.
I am using the command cat D:\Python\test-inputs.txt| python a3p1.py
The output should be outlying the process from the file. I am reading my stdin input with
while True:
line = sys.stdin.readline()
if not line:
break
words = line.split()
for word in words:
breakdown(database, word)
Can anyone help me
It might be a bit cleaner to do something like this:
foreach ($line in (cat inputs.txt) {
python a3p1.py $line
}
and then you can code your python script to accept arguments which will be in the format of the lines you are inputting.
Although you could just write your python file to read the file in too.
It's a little unclear what you're asking.
You probably want to use
cat D:\Python\test-inputs.txt > a3p1.py
| is for piping STDOUT from a program into another program's STDIN, > is for piping STDOUT (from cat in this case) into a file.
Alternatively, to use test-inputs.txt as STDIN for your python program, you can use:
python a3p1.py < test-inputs.txt
| to pipe from stdout of cat into a python program as the OP suggested.
