结果
image = Image.open(newest)
exif = image._getexif()
gps = {}
datebool = False
gpsbool = False
date = 'None'
time = 'None'
gpstext = 'None'
dmslat = 'None'
dmslon = 'None'
if exif is not None:
for tag, entry in exif.items(): #Import date and time from Exif
datebool = True
if TAGS.get(tag, tag) == 'DateTimeOriginal':
date = entry[0:10]
time = entry[11:19]
for tag, entry in exif.items(): #Check if the GPSInfo field exists
if TAGS.get(tag,tag) == 'GPSInfo':
gpsbool = True
for e in entry:
decoded = GPSTAGS.get(e,e)
print (decoded)
print(type(entry))
gps[decoded] = entry[e]
由于e是从条目中提取的，如何从条目中索引特定的e会产生索引错误？我实际上是在为gps提取正确的数据吗？
答案 0 :(得分：0)
entry = (3, 5, 7)
for e in entry:
print(e)
不会为条目中的值编制索引，而是迭代它们。例如：
3
5
7
将输出：
gps[decoded] = e
所以该行应该看起来像：
GPSTAGS虽然我不确定entry行会变成什么样。如果您确实需要枚举enumerate()中的项目，那么您应该查看（令您惊讶的是，我确定）UIViews函数。
