How to capture stdout in real-time with Python
This solution is thanks to this article.
import subprocess
def myrun(cmd):
"""from http://blog.kagesenshi.org/2008/02/teeing-python-subprocesspopen-output.html
"""
p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
stdout = []
while True:
line = p.stdout.readline()
stdout.append(line)
print line,
if line == '' and p.poll() != None:
break
return ''.join(stdout)
