TypeError: unorderable Typen: NoneType()> int()

Question

Ich bin neu in Python3, und bekomme den folgenden Fehler versucht, Erdbebendaten vom letzten Tag zu lesen !!

Traceback (most recent call last): 
    File "Z:\Python learning\Up and run\Exercise Files\Ch5\jsondata_finished.py", line 54, in <module> 
    main() 
    File "Z:\Python learning\Up and run\Exercise Files\Ch5\jsondata_finished.py", line 49, in main 
    printResults(data) 
    File "Z:\Python learning\Up and run\Exercise Files\Ch5\jsondata_finished.py", line 33, in printResults 
    if (feltReports != None) & (feltReports > 0): 
TypeError: unorderable types: NoneType() > int() 

Ich kann den Fehler nicht identifizieren. Hier ist mein CODE:

import urllib.request 
import json 

def printResults(data): 
    # Use the json module to load the string data into a dictionary 
    theJSON = json.loads(data.decode()) 

    # now we can access the contents of the JSON like any other Python object 
    if "title" in theJSON["metadata"]: 
    print (theJSON["metadata"]["title"]) 

    # output the number of events, plus the magnitude and each event name 
    count = theJSON["metadata"]["count"]; 
    print (str(count) + " events recorded") 

    # for each event, print the place where it occurred 
    for i in theJSON["features"]: 
    print (i["properties"]["place"]) 

    # print the events that only have a magnitude greater than 4 
    # for i in theJSON["features"]: 
    # if i["properties"]["mag"] >= 4.0: 
     # print "%2.1f" % i["properties"]["mag"], i["properties"]["place"] 

    # print only the events where at least 1 person reported feeling something 
    print ("Events that were felt:") 
    for i in theJSON["features"]: 
    feltReports = i["properties"]["felt"] 
    if (feltReports != None) & (feltReports > 0): 
     print ("%2.1f" % i["properties"]["mag"], i["properties"]["place"], " reported " + str(feltReports) + " times") 


def main(): 
    # define a variable to hold the source URL 
    # In this case we'll use the free data feed from the USGS 
    # This feed lists all earthquakes for the last day larger than Mag 2.5 
    urlData = "http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_day.geojson" 

    # Open the URL and read the data 
    webUrl = urllib.request.urlopen(urlData) 
    print (webUrl.getcode()) 
    if (webUrl.getcode() == 200): 
    data = webUrl.read() 
    # print out our customized results 
    printResults(data) 
    else: 
    print ("Received an error from server, cannot retrieve results " + str(webUrl.getcode())) 

if __name__ == "__main__": 
    main() 

Bitte helfen Sie! Ich habe versucht, ein paar Dinge zu überdenken, indem ich mir die Lösungen anderer Benutzer angeschaut habe, aber ich habe immer wieder den gleichen Fehler bekommen.

Verwenden Sie and anstelle von &. Verwenden Sie auch is not None, um zu überprüfen, ob das Objekt nicht None statt != None
