Python 在使用 JSON 进行 for 循环后停止运行

Question

我正在用 Python 做一个 JSON 教程，我意识到代码直到最后才运行。这是代码：## 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"我知道这不是缩进，因为我可以单独运行每个 for 循环，即如果我注释第一个 for 循环，则运行第二个 for 循环。我在这里缺少什么吗？谢谢！

你的代码运行良好。尝试检查代码的缩进。也许你需要它。

这是你的结果：
