Why can I not the change the value of a variable in another class,
when I have passed it via a parameter list.
I am sure I am being stupid, but I thought passed objects were Read/
Write
eg
------------------------------------------------------------
#!/usr/bin/python
class one(): #my Global Vars
fred = 'fred'
class three():
def createJoe(self, myName):
c1 = one()
myName = 'Joe' #********************* Question why does this
not change variable fred in 'class one'
print 'Three(Local): ' + myName + ' Three(Global): ' +
c1.fred
def main():
c1 = one()
c3 =three()
c3.createJoe(c1.fred)
if __name__ == '__main__' : main()
Results:
Three(Local): Joe Three(Global): fred
'fred' in 'class one' does not get changed to 'joe' in 'class three'
'createJoe', even though I have passed 'class one' 'fred' to
'createJoe'
I hope this makes sense.
I did not think you had to make the distinction between 'byvar' and
'byref' as in Basic.
Thanks
Richard
