How can gave the attributes __name__ to a function?
You don't Python does it for you.
class Foo(object):
def __init__(self):
steps = {}
tmp = open("rnaseq.base.ini","rb")
config.readfp(tmp)
readsets =
parse_illumina_readset_file("/home/mauro/Desktop/readset.csv")
You realise that steps is a local variable that is not used and gets
thrown away. So its a waste of space.
Similarly you read the config file but throw away the results.
Again a waste of space.
And the same with readsets.
Your init does a lot of work to no long term effect.
@property
def steps(self):
return [
self.one,
self.two,
self.fmit,
]
def one(self):
a = 5
return a
...
#@property
def show(self):
ftp="\n".join([str(idx + 1) + "- " + step.__name__ for idx, step in
enumerate(self.steps)])
print ftp
It is working
In [5]: F = Foo()
In [6]: F.show()
1- one
2- two
3- fmit
Yes, as expected.
Why if I define the data in the same way I have this error?
<ipython-input-83-a3c57022a089> in <module>()
----> 1 rna.show()
<ipython-input-79-b1a3b6d221ae> in show(self)
261 #@property
262 def show(self):
--> 263 ftp="\n".join([str(idx + 1) + "- " + step.__name__ for
idx, step in enumerate(self.steps)])
264
265 print ftp
AttributeError: 'str' object has no attribute '__name__'
Because you didn't define it in the same way.
Consider this example from the pastebin:
@property
def star(self):
print "Mitico Star"
return "name"
Here you make star a property so when in steps you store self.star you
are not storing a reference to the method, as you did above, you are
storing the return value of star - "name".
Now in show() you try to take the __name__ of "name" but, as the error
says, strings don't have __name__ attributes.
The same applies to some, but not all, of the other method names in steps...
You would make life much easier if you got rid of all the property stuff
(some of it commented out and others not). Just use the
methods and data attributes directly, it makes life so much easier.
Here you find all the other code the principal are the
same:http://pastebin.com/nYGEiXY4
