Hi there,
I'll ask for some patience and forgiveness in advance. Im about 2 weeks in to Python devleopment, so Im likely missing some obvious approaches - please dont assume a lot of knowledge on my part if you can help.
Objective: I've been tasked with 'crawling' through folders on DropBox via the API to look for certain image types (specific file extensions only - *.dco for reference - as I wont have knowledge of the file names), and then extracting the path and filename (and then 'do stuff'). Locally I have already completed this code (in other words, if the files are on my computer it works fine) - but now it needs to work in DropBox as well because the data sets will be quite large. I cannot assume that the files in the folders will be the types I want - hence I need to search for filename extensions.
I have access to the DropBox and authorization sorted. I've created a folder and put in some temp files (which are the pdf's and jpeg's provided by DropBox for testing). I can query the folder, and return a list of results via files_list_folder.
I can get a list of files, extensions and paths via the code below - however the issue I am having is that I cannot parse the data based on file extension, and the rudementary methods I am using are not working.
While I can get a list of files, and even 'copy' them to another list - I cannot find a way to parse the list to give me the path_lower/ the directory and filename - which will give me the extension (ie: find all *.jpg's). I must be missing something in the manner in which the data is constructed (I understand its instance/object based). I have been assuming Im not hitting on the correct keyword combinations to extract the data - so Im looking for some help in identifying where Im going wrong. Thanks in advance!
my_client=Dropbox(token)
folderfile_list = my_client.files_list_folder('', True, True)
#this gives me a nice list of items - however I dont seem to be able to *do* anything with it
for item in folderfile_list.entries:
if isinstance(item, dropbox.files.FileMetadata):
name = item.name
fileID= item.id
fileHash = item.content_hash
path= metadata.path_lower
print(name, path)
#This does return the search results I want - but its not iterable - so I dont seem to be able to do anything with it
files_search = my_client.files_search('', '*.pdf')
print(files_search)
type(files_search)

for i in folderfile_list.entries:
fname.append(i)
print(fname[1])
import fnmatch
pattern ='*.jpg'
matching = fnmatch.filter(fname, pattern)
print(matching)
#this did work - however I cannot find a file TYPE with this - the specific file #name I can find - but not the file extension
#In other words if I change this it *.pdf - it does not get a 'happy' result 
for files in fname:
if files.path_lower == '/test folder/strategy-session-hotel.pdf':
print("happy")
print(files.path_lower)
else:
print('unhappy')
