sounds you want something like this:
#!/usr/bin/python
import a
import b
import sys
import StringIO
output = StringIO.StringIO()
def c():
# save default stdout
tout = sys.stdout
# redirect stdout to StringIO object
sys.stdout = output
# a.a() prints their output to StringIO object
a.a()
# back up default stdout
sys.stdout = tout
# print StringIO object value
print "retval:", output.getvalue()
c()
a.
