python缩进错误

Question

python新手，一直在写这个大概一个小时。 Google文档api和示例非常棒。我可以连接并创建文件等。我想将我的所有文件备份到谷歌驱动器，因此尝试使用os.walk，并遇到了我不明白的持续缩进错误。

#!/usr/bin/python 

import httplib2 
import pprint 
from apiclient.discovery import build 
from apiclient.http import MediaFileUpload 
from oauth2client.client import OAuth2WebServerFlow 
from oauth2client.client import Credentials 
import os 
import sys 

rootdir = sys.argv[1] 

CLIENT_ID = 'MYCLIENT ID' 
CLIENT_SECRET = 'MY SECRET ID' 
OAUTH_SCOPE = 'https://www.googleapis.com/auth/drive' 

# Redirect URI for installed apps 
REDIRECT_URI = 'urn:ietf:wg:oauth:2.0:oob' 

json_creds = open('backup_credentials.json', 'r').read() 
credentials = Credentials.new_from_json(json_creds) 
# 
# Create an httplib2.Http object and authorize it with our credentials 
http = httplib2.Http() 
http = credentials.authorize(http) 
drive_service = build('drive', 'v2', http=http) 

#Here is where the problem starts 
for root, subFolders, files in os.walk(rootdir): 
    for filename in files: 
     filepath = os.path.join(root, filename) 
     print (filepath) 
     media_body = MediaFileUpload(filepath, mimetype='text/plain', resumable=True) 
     body = {'title': filename,'description': 'A test document','mimeType': 'text/plain'} 
     file = drive_service.files().insert(body=body, media_body=media_body).execute() 
     pprint.pprint(file) 

的违规错误行文件= ...

实际的错误是

File "./quickstart.py", line 59 
    file = drive_service.files().insert(body=body, media_body=media_body).execute() 
                      ^
IndentationError: unindent does not match any outer indentation level 

Answer 1

你有

body = { 
    'title': filename, 
    'description': 'A test document', 
    'mimeType': 'text/plain' 
    } 
    file = drive_service.files().insert(body=body, media_body=media_body).execute() 
    pprint.pprint(file) 

时，你应该有：

body = { 
    'title': filename, 
    'description': 'A test document', 
    'mimeType': 'text/plain' 
    } 
    file = drive_service.files().insert(body=body, media_body=media_body).execute() 
    pprint.pprint(file) 

请注意，file =行应缩进到与缩进行“上面”的行相同的级别（body = ...）。
