Python 3.5: json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) -


i have piece of python code:

homedir = '/home/cloudera/' baseurl = 'http://ergast.com/api/f1/'  apilist = ['seasons', 'results', 'qualifying', 'driverstandings', 'constructorstandings', 'drivers', 'constructors',            'circuits', 'status', 'laps', 'pitstops']  dir in apilist:     target = homedir + str(dir)     try:         shutil.rmtree(target, ignore_errors=true)         os.makedirs(target)     except:         pass  parent_url = baseurl + "{y}/{api}.json?limit=100000" parent_fname = homedir + "{api}/{yf}.json"   urls = [parent_url.format(y=y, api=a) y, in itertools.product(range(1950, 2016), apilist)] files = [parent_fname.format(yf=y, api=a) y, in itertools.product(range(1950, 2016), apilist)]   url, file in zip(urls, files):     print(url, file)     response = requests.get(url).json()     open(file, 'w') f:        json.dump(response, f)

when run this, output get:

basically, creates json files year 1950, next time loop runs year 1951, exits. i'm new python , newer still json. can figure out what's going on?

note: less complex version of program, years 1950 2015, qualifying had worked. trying go large scale , attributes together. version merely used range iterate through years , generate file names , urls.

this problem raised because url: http://ergast.com/api/f1/1950/laps.json?limit=100000 returns error. url:http://ergast.com/api/f1/1950/status.json?limit=100000 (image above)enter image description here image have working json format, , source page is: enter image description here

the url:http://ergast.com/api/f1/1950/laps.json?limit=100000 return html error:enter image description here

and source of url html table , not json format:enter image description here

this error can suppresed using error treatment, cant resolve format. maybe need other argument in url return corret values. link: http://ergast.com/mrd/ have documentation of api, , in section overview says:

enter image description here

if try put numeric value url after year, : http://ergast.com/api/f1/1950/1/laps.json?limit=100000 return valid results, image:enter image description here

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
