I have a single-thread python script that gets used like this:

python -c "arg"

I also have a *.txt file with many arg, each in one single line in the respective *.txt. A text file, say 1.txt looks as follows:

arg1

arg2

arg3

arg4

Now I want to run the python script with all this arguments, one by one as the script does not allow more than one argument.

How can I process this arguments in batch mode using commandline?
