Hi
I have been toying with json and I particular area where I cannot get the
desired result a list of tuples as my return. The json from the API is way to
long but I don't think it will matter.
.. hitting url
data = r.json()
for item in data["RaceDay"]['Meetings'][0]['Races']:
raceDetails

Hi
I have got a successful script setup to rotate through dates and download json
data from the url.
As the api returns 200 whether successful I want to check if the file returned
is not successful.
when a file doesn't exist the api returns
{'RaceDay': None, 'ErrorInfo': {'SystemId': 200, 'Err
Thank you it was data["RaceDay"] that was needed.
ata = r.json()
if data["RaceDay"] is None:
print("Nothing here")
else:

Nothing here
Nothing here
Nothing here

How do I create a valid file name and directory with pathlib?
When I create it using PurePosixPath I end up with an OSError due to an

Sorry
figured it. Needed to use n to iterate when creating.
runner_lists = {}
for n, item in enumerate(result):
# if this one is interested / not -filtered:
print(n, item)
runner_lists[n] = result[n]["RacingFormGuide"]["Event"]["Runners"]

no doubt tho after playing with this is that enumerate value ends up in the
output which is a dictionary. The enumerate has no key which makes it invalid
json if dumped.
Not massive issue but getting the effect of enumerate without polluting output
would be the winner.

Hi
Trying to clarify why ints and strings arent treated the same.
You can get a valuerror from trying to cast a non-int to an int as in int(3.0)

a non-int with valuerr

My main issue is that usually its just x in ,,, for a generator.
But if I change the code
for meet in roots.iter("meeting"):
to
for meet in roots("meeting"):
Well its invalid but I need to be able to reference the node, how do I achieve
this?

(2) attrs is a dict, so iterating over it will lose the values. Are you sure

from pyquery import PyQuery as pq

sys.exit(1)
dir = sys.argv[1]
mask = sys.argv[2]
files = os.listdir(dir)
fileResult = filter(lambda

Hi
This file contains my biggest roadblock with programming and that's the
abstract nature of needing to pass data from one thing to the next.
In my file here I needed to traverse and modify the XML file I don't want to
restore it or put it in a new variable or other format I just want to alter

Looking at various Python implementations of Conway's game of life.
I came across one on rosetta using defaultdict.
http://rosettacode.org/wiki/Conway%27s_Game_of_Life#Python
Just looking for your opinion on style would you write it like this continually
calling range or would you use enumerate
Also not using enumerate but no ugly for i range implementation
this one from code review uses a generator on live cells only.

def neighbors(cell):
x, y = cell
yield x - 1, y - 1
yield x, y - 1
yield x + 1, y - 1
yield
1 - 100 of 236 matches
