我正在用 Python 做一個 JSON 教程，我意識到代碼直到最后才運行。這是代碼：## Example file for parsing and processing JSON#import urllib.request # instead of urllib2 like in Python 2.7import jsondef printResults(data): # Use the json module to load the string data into a dictionary theJSON = json.loads(data) # 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"]) # # # code doesn't work from here # # # print("--------------\n") # # 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("--------------\n") # # print only the events where at least 1 person reported feeling something print("\n\nEvents that were felt:") for i in theJSON["features"]: feltReports = i["properties"]["felt"] if (feltReports != None): if (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 = "https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_day.geojson"我知道這不是縮進，因為我可以單獨運行每個 for 循環(huán)，即如果我注釋第一個 for 循環(huán)，則運行第二個 for 循環(huán)。我在這里缺少什么嗎？謝謝！

你的代碼運行良好。嘗試檢查代碼的縮進。也許你需要它。
