OK, I know this is covered somewhere in Python 101, but for the life of me
I cannot figure this out. I really need a basic intro to Python book....
I am trying to do something very simple - create an HTML tag using objects:
class Movie:
def __init__ (self, t="", a="", d=""):
#
# Create an instance of Movie
#
self.title = t
self.audience = a
self.driver = d
def set_title (self, new_title):
self.title = new_title
def set_audience (self, audience):
#
# Only 3 valid values: kids, parents, guests
#
self.audience = audience
def set_driver (self, new_driver):
self.driver = new_driver
def url (self):
self.url = "avi://" + self.audience + "/" + self.title + "/" +
self.driver
def thumb (self):
self.thumb = self.audience + "/tn/" + self.title + ".jpg"
def html (self):
print "<a href=avi://" + self.audience + "/" + self.title + "/" +
self.driver + "> <img src=" + self.thumb + ">" + self.title + "</a>"
#
# Code to test this class
#
if __name__ == '__main__':
print "**** Test 1 ****"
m=Movie("Fate_is_the_Hunter")
m.set_audience ("kids")
m.set_title ("Fate_is_the_Hunter")
m.set_driver
("X=hermes.seiner.lan:xv,athena.seiner.lan:xmga,default:x11;console=vesa")
m.html ()
print "*** Finish ***"
The problem is that m.html in the test section fails with
TypeError: cannot concatenate 'str' and 'instancemethod' objects
I got it working once. The output should be something like this:
<a
href=avi://kids/Fate_is_the_Hunter/X=hermes.seiner.lan:xv,athena.seiner.lan:xmga,default:x11;console=vesa>
<img src=kids/tn/Fate_is_the_Hunter.jpg>Fate_is_the_Hunter</a>
but then I made some minor edits and I can't get it to work again....
Where do I find documentation on Python classes? Or how do I convert one
to the other? Or, how do I get the above to work? This is the first time
I've really tried to work with a class I've defined myself and I obviously
don't know what I am doing....
On a minor note, if you look at the audience method, I want to limit it to
3 values. How do I do that?
TIA....
