If you run this application from the command line, you get command
recall and editing when entering strings at the "cmd:" prompt?
#!/usr/bin/python
while True:
try:
line = input('cmd: ')
except EOFError:
print()
break
print('You entered "%s"' % line)

I "get readline behavior" in the REPL without an "import readline",
but that's irrelevent. We're talking about a command-line
application that's calling input().
