在请求"键"时,如何获取列表中项目的值?
e.g。我目前有以下列表:
[{'rev': '1', 'time': '1448300582', 'action': 'move/add', 'title': 'test.log'}, {'rev': '0', 'time': '1448300582', 'action': 'delete', 'title': 'python.py'} {'rev': '12', 'time': '1448300582', 'action': 'move/add', 'title': 'Hello.txt'}]
如何循环打印每个文件的标题和修订
Dictionary = [{'rev': '1', 'time': '1448300582', 'action': 'move/add', 'title': 'test.log'}, ...
KeyList = ['rev', 'time', 'action', 'type', 'title']
for Key in KeyList:
print Key, "=", Dictionary[title]
我目前收到以下错误:
Traceback (most recent call last):
File "P:/Scripts/PerforceSearchTool.py", line 45, in <module>
GetFiles()
File "P:/Scripts/PerforceSearchTool.py", line 28, in GetFiles
print Key, "=", Dictionary[depotFile]
NameError: global name 'depotFile' is not defined
最后的列表将包含数千个文件。我希望能够在列表中搜索每个文件标题。并且对于匹配的标题,根据其动作返回其标题。

您可以使用for循环:
mylist = [{'rev': '1', 'time': '1448300582', 'action': 'move/add', 'title': 'test.log'}, {'rev': '0', 'time': '1448300582', 'action': 'delete', 'title': 'python.py'}, {'rev': '12', 'time': '1448300582', 'action': 'move/add', 'title': 'Hello.txt'}]
for i in mylist:
print("Title: {}, Revision: {}".format(i["title"],i["rev"]))
输出:
Title: test.log, Revision: 1
Title: python.py, Revision: 0
Title: Hello.txt, Revision: 12

试试这个:
a = [{'rev': '1', 'time': '1448300582', 'action': 'move/add', 'title': 'test.log'}, {'rev': '0', 'time': '1448300582', 'action': 'delete', 'title': 'python.py'} {'rev': '12', 'time': '1448300582', 'action': 'move/add', 'title': 'Hello.txt'}]
for x in range(len(a)):
print a[x]['title']
print a[x]['rev']
