Wesley,
thanks for your reply. I was surprised about the limited information
too. Sadly (?), I can't reproduce the error any more...

I just wrote this message, but after restarting ipython all worked
fine.
How is it to be explained that I first had a namespace error which,
after a
restart (and not merely a new "run Sande_celsius-main.py"), went
away? I
mean, surely the namespace should not be impacted by ipython at all!?
:
# file: Sande_celsius-main.py
from Sande_my_module import c_to_f
celsius = float(raw_input("Enter a temperature in Celsius: "))
fahrenheit = c_to_f(celsius)
print "That's ", fahrenheit, " degrees Fahrenheit"
# this is the file Sande_my_module.py
# we're going to use it in another program
def c_to_f(celsius):
fahrenheit = celsius * 9.0 / 5 + 32
return fahrenheit
When I run Sande_celsius-main.py, I get the following error:
NameError: global name 'celsius' is not defined
WARNING: Failure executing file:<Sande_celsius-main.py>
Python interpreters including the standard one or IPython should tell
you a lot more than that. how are you executing this code? would it be
possible to do so from the command-line? you should get a more verbose
error message that you can post here.
best regards,

Your response to Wesley should have been here, instead of at the top.
Please don't top-post on this forum.
I don't use iPython, so this is just a guess. But perhaps the problem
is that once you've imported the code, then change it, it's trying to
run the old code instead of the changed code.
Try an experiment in your environment. Deliberately add an error to
Sande_celsius-main.py, and run it. Then correct it, and run it again,
to see if it notices the fix.
The changes I'd try in this experiment are to first change the name on
the celsius= line to celsius2=
and after running and getting the error, change the following line to
call celsius2(). If it gets an error, notice what symbol it complains
about.
