Hi,
I have just been thrown through an unecessary loop because of an unhelpful
error message.
I am running Python 2.7.10 on a Windows 10 machine.
I incorporate sample output from IDLE:
~~~~~~~~~~~~~~~~~~~~~~~~~~~
>>> print float ("123.456")
123.456
>>> print float ("")
Traceback (most recent call last):
File "<pyshell#60>", line 1, in <module>
print float ("")
ValueError: could not convert string to float:
>>>
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The unhelpful message is the response that the system gives when you try to
convert a null string to a floating point number. Now, in the example I
have given here, it is obvious that the string is null, but in the example
that threw me into a loop, it was not obvious.
It would be more helpful is the system replied:
ValueError: could not convert null string to float
Any chance of that becoming the case?
Stephen Tucker.
