json - Python - global variable is not defined (but it is) -

-

Then I am working on this file which converts CSV to JSON, however I get this error message I can not but understand that indentation seems right, so why have I lost it to go with it. The code is below:

Traceback (the most recent call last): 

  file "/ home / uwp / widgets / contentFreshness / freshmap Py ", line 308, & lt; Module & gt; In the file "/home/uwp/widgets/contentFreshness/freshmap.py", line 247, in the main () file "/home/uwp/widgets/contentFreshness/freshmap.py", line 303, main mySite.writeJSONFile (option) WriteJSONFile outputFile.write ('' + str (dateOfCrawl) + '' ') NameError: global name' dateOfCrawl 'is not defined

code

class site: dateOfCrawl = 0; Def __init __ (self, csvFilePath): self.pageList = [] # Page id self.pageData list ordered = {} page person dictionaries, = {} unique title of self-indexed on the # page page self.titleDict # dictionary. BuildPageData (csvFilePath) self.homePageId = self.pageList [0] # only site.pageList self.depth = 0 Use of def buildPageData (self, csvFilePath): global dateOfCrawl #, read data from a CSV file, The page URL = line [0] pageURL = re.sub ('\ / \ Z', '', for the line in lines, the order line = csv.reader (open (csvFilePath, "rb")) , PageURL) # Remove any trailing slash yourself. Pageadata [page URL] = {} self PageData [page URL] ["url"] = page ur own Pagedata [page url] ["title"] = self Scantital (line [1], page url) # The parent should be http: / # while taking the home page and its URL (parent == 'http: /'): set to 'parent = choppath (pageURL)' Avoids doing so: parent = '' dateOfCrawl = line [2] self.pageData [pageURL] ["parent"] = Parents self page data [page URL] ["modified"] = line [2] Pageadata [page URL] ["child"] = [] list = self Pageadata.kiz () # Sort ID before attempting to match the child. Self.pageList = self .pageData.keys () self.pageList.sort () lineCount = 0 Page URL for self.pageList: # Records page as the parent of his parents (Parents are already on the list !) ParentURL = self.pageData [pageURL] ["guardian"] if (line count> 0): while (self.pageData.has_key (parentURL == incorrect): if (parent == ''): sys. Exit (pageURL + "no parent at parent URL) parentURL = choppath (parentURL) self page.Data [parent URL] [" child "] attached (PAGEURL) lineCount + = 1 self.pageCount = lineCount def writeJSONFile (auto, option ): Global dateOfCrawl outputfile = option ["outputfile"] #See http://code.google. Com / Intl / en / apis / view / documentation / reference.html # DataTable outputFile.write ('['] outputFile.write ('' + str (dateOfCrawl + '' ')) self.homePage.toJSON (option) OutputFile .write (')' outputfile.close ()

you dateoff crawl = 0; (Please read) for any reason as class attribute , you are also mixing in a global , which is completely different It's not really clear why dateOfCrawl is a class (instead of an example) attribute, or why you have global too. You should hardly:

  1. Make it a frequency attribute ( dateOfCrawl = 0 inside __init __ );
  2. Go to that in other ways ( self.dateOfCrawl )

class - Kivy: how to instantiate a dynamic classes in python -

Using KV lang on my Python code, I have taken a hard time trying to instantiate a dynamic class, the following Consider the code: My test.kv file looks like this: & lt; MyPopup @ popup: Title: 'Hello' size_hunt: (1, .6) Grid layout: ID: RouteGrid column: 2 padding: ['8dp', '4dp', '8dp', '4dp'] Difference: '8dp' label: text: 'some text here' button: text: 'OK' On_press: do_something () & lt; MyGrid & gt;: Rows: 1 Button: Text: 'Show Popup' on_press: root.pop.show () Then import Kivy.app into my test.py: I get the following error: raise Factory Exception ('Uncount Class' '% name) kivy.factory.FactoryException: Unknown class Can anyone tell me how to do this properly, what do I remember? If you need more information please let me know Thank you. Takes a call to the factory before the KV file is loaded, so you want the class to Are not yet in existence. As long as no clas...

python - mayavi mapping a discrete colorbar on a surface -

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
