Run Perl code (with output to file) from Python

Question

I\'m trying to run a Perl script from Python. I know that if run the Perl script in terminal and I want the output of the Perl script to be written a file I need to add

Answer 1

subprocess.call("perl myCode.pl >results.txt", shell=True)

or

subprocess.call(["sh", "-c", "perl myCode.pl >results.txt"])

or

with open('results.txt', 'wb', 0) as file:
    subprocess.call(["perl", "myCode.pl"], stdout=file)

The first two invoke a shell to execute the shell command perl myCode.pl > results.txt. The last one executes perl directly by having call do the redirection itself. This is the more reliable solution.
