python - 在python中写入文件

Question

在下面的代码中，我只是想将我从 flickr 获得的数据以一种简洁的方式写入一个文件中，以备后用。然而，尽管控制台没有抛出任何错误，但没有任何内容写入我的文件。谁能帮我解决这个问题，在此先感谢您!

import flickrapi

api_key = "xxxxxxxxxxx"
secret_api_key = "xxxxxxxxxxxxxxxx"
flickr = flickrapi.FlickrAPI(api_key, secret_api_key)

def obtainImages():

    photo_list = flickr.photos.search(api_key=api_key, has_geo=1, per_page = 500)
    file = open("obtainedImages.txt", "w")

    for photo in photo_list[0]:
        photo_location = flickr.photos_geo_getLocation(photo_id=photo.attrib['id'])

        id = str(photo[0].attrib['id'])
        lat = str(photo_location[0][0].attrib['latitude'])
        long = str(photo_location[0][0].attrib['longitude'])

        file.write("%s" %id)
        file.write(' ')
        file.write("%s" % lat)
        file.write(' ')
        file.write("%s" % long)
        file.write('\n')

obtainImages()

这是更新后的代码，再次显示没有错误，但没有向文件写入任何内容。经纬度打印正常

import flickrapi

api_key = "xxxxxxxxxxxxxxxxx"
secret_api_key = "xxxxxxxxx"
flickr = flickrapi.FlickrAPI(api_key, secret_api_key)

def obtainImages():

    photo_list = flickr.photos.search(api_key=api_key, has_geo=1, per_page = 500)
    file = open("obtainedImages.txt", "w")

    for photo in photo_list[0]:

        photo_location = flickr.photos_geo_getLocation(photo_id=photo.attrib['id'])
        lat = str(photo_location[0][0].attrib['latitude'])
        long = str(photo_location[0][0].attrib['longitude'])

        file.write("%s" % lat)
        file.write(' ')
        file.write("%s" % long)
        file.write('\n')

    file.close()
obtainImages()

Answer 1

在 obtainImages() 方法的末尾添加 file.close()。

def obtainImages():

    photo_list = flickr.photos.search(api_key=api_key, has_geo=1, per_page = 500)
    file = open("obtainedImages.txt", "w")

    for photo in photo_list[0]:
        photo_location = flickr.photos_geo_getLocation(photo_id=photo.attrib['id'])

        id = str(photo[0].attrib['id'])
        lat = str(photo_location[0][0].attrib['latitude'])
        long = str(photo_location[0][0].attrib['longitude'])

        file.write("%s" %id)
        file.write(' ')
        file.write("%s" % lat)
        file.write(' ')
        file.write("%s" % long)
        file.write('\n')
    file.close()  ## add here
