I have the following code:
from __future__ import division, print_function
import subprocess
p = subprocess.Popen('ls -l', shell = True, stdout = subprocess.PIPE)
for line in iter(p.stdout.readline, ''):
print(line.rstrip().decode('utf-8'))
p = subprocess.Popen('ls -l', shell = True, stdout = subprocess.PIPE)
for line in p.stdout.readlines():
print(line.rstrip().decode('utf-8'))
This works in Python2. (Both give the same output.)
But when I execute this in Python3, then the first loop is stuck in a
loop where it continually prints a empty string. The second loop is
executed correctly in Python3.
In the current case it is not a problem for me, but when the output
becomes big, the second solution will need more memory. How can I get
the first version working in Python3?
