As help(calc.communicate) says:
Read data from stdout and stderr, until end-of-file is reached.
Wait for process to _terminate_.

Simplest solution:
#!/usr/bin/python2.4
import subprocess
calc = subprocess.Popen("dc", stdin=subprocess.PIPE, stdout=subprocess.PIPE,
stderr=subprocess.STDOUT)
max = 5
for value in range(1, max):
calc.stdin.write("%d\n" % value)
if value > 1:
calc.stdin.write("*\n")
calc.stdin.write("p\n")
calc.stdin.write("q\n")
calc.stdin.flush()
status = calc.wait()
print calc.stdout.read()
