Hello,
I've managed to muddle my way through python for the last while and have
finally come up with something I dont know how to deal with.
(I have included a simplified code group below that represents what m
trying to do and see)
I have a main module (test6.py) which calls a configuration module
(test8.py) and then a number of other modules (test7 etc) which use the
data from the configuration module. (ie: configuration.output returns
"excel")
when I run the code I get the following error:
C:\Python33\python.exe C:/Users/dcrisp/Documents/Python/gui/test6.py
sql
Traceback (most recent call last):
excel
File "C:/Users/dcrisp/Documents/Python/gui/test6.py", line 10, in
<module>
mainWin = test7.MainWindow()
File "C:\Users\dcrisp\Documents\Python\gui\test7.py", line 5, in
__init__
if configuration.input.upper() == "EXCEL":
NameError: global name 'configuration' is not defined
Which is telling me that configuration isnt a global ...
Help? please? OKay, an actual question.
How do I read the configuration opbject from within test7 when it is
called from test6? I dont really want to call it from every module
that needs it as there is meant to be some write back functionality
happening to a configuration file and if I try and do that from more
than one entry point I will end up writing a corrupted config back. So
A single entry point for configuration would be nice..
Or am I doing it wrong?
Whats the best way of doing what I want to do.
Again, if I havent asked the right questions, please guide and I will
try and provide the information you need.
Regards,
David Crisp
Three simplified files provided below.
Module 1:
test6.py
import test8
import test7
if __name__ == '__main__':
configuration = test8.client_configuration()
print(configuration.output)
print(configuration.input)
mainWin = test7.MainWindow()
pass
Module 2:
test7.py
class MainWindow():
def __init__(self):
This class doesn't get "configuration" declared or passed in or
otherwise made available to it. You could do ...
def __init__(self, configuration):
... which would at least generate an error if you don't pass it in.
if configuration.input.upper() == "EXCEL":
print("excel in")
elif configuration.input.upper() == "SQL":
print("SQL in")
else:
print("Inappropriate Configuration Set")
When running test6 the following code in test7 never runs. It only runs
if test7 is run independently.
if __name__ == '__main__':
import test8
configuration = test8.client_configuration()
mainWin = MainWindow()
pass
Module 3:
test8.py
class client_configuration():
def __init__(self):
self.input = "excel"
self.output = "sql"
ditto for test8
if __name__ == '__main__':
configuration = client_configuration()
print(configuration.input)
print(configuration.output)
