Hello,
thank you for the patch
1)
- except ValueError:
+ except EOFError, ValueError:
Please use
except (EOFError, ValueError):
https://docs.python.org/2/tutorial/errors.html#handling-exceptions
OK, I will include this.
2)
I'm not sure if this code will work (I did not test it)
I expect when stdin is closed, this will result into infinite
loop, because raw_input will always return EOFError.
while True:
try:
ret = raw_input("%s: " % prompt)
if allow_empty or ret.strip():
return ret
except EOFError:
pass
Could you please elaborate more on, so that I can include fix in
this section of code?
If you receive EOF you cannot continue in while cycle because, it
will return EOF every iteration forever.
If EOF is received the while cycle must end, and appropriate action
must be take.
It depends on situation, if default value is present then default
value should be used, or in case if empty value is allowed, empty
string should be returned.
In case there is no default value and empty value is not allowed,
then an exception should be raised.

NACK
There is still infinity loop.
1)
+ except EOFError:
+ if allow_empty:
+ return ''
This will continue in while cycle if allow_empty=False, you need to raise
exception there.
2)
Why so complicated? just return default looks enough to me.
+ except EOFError:
+ if choice.lower()[0] == "y":
+ return True
+ elif choice.lower()[0] == "n":
+ return False
3)
Remove this change please
