hi.
for 2 open source components of mine that are used in debugging, i
would like to capture the output generated by print for any variable.
i'm new to python, so please excuse my noobishness.
i don't know if objects can be json-ed as easy as lists and hash
tables are by print.
and i couldn't find how to capture the output generated by print into
a string, so i can't use it with google appengine :(
i'm in dire need of some expert advise here.
Lookup the 'StringIO' module (Python 2.x):
from StringIO import StringIO
import sys
old_stdout = sys.stdout
saved_output = StringIO()
try:
sys.stdout = saved_output
print "Hello world!"
finally:
sys.stdout = old_stdout
print saved_output.getvalue()
