Question

我对python很陌生，我试图创建能够完成我手工完成的所有工作的循环。基本上创建所有行＃＆＃39; 变量，并从文件＆＃39; game_catch.txt＆＃39; 中分配特定的文本行。读到这样的东西：

Curving                 10
Dodgeball               15
Keep Away               5
Kin-Ball                7
Prisoner Ball           21
Quidditch               30
Rundown (aka Pickle)    12
Yukigassen              18
Handball                25

（空格为Tabs，如果有任何区别的话）

然后创建另一个循环，在分割时将行＆＃39; 变量的值分配给 str＆＃39;＃＆＃39; 变量所有的间距。（我无法修改该文件，因为在其他计算机中它将与我上面发布的文件相同，所以我必须执行此步骤）

然后，更重要的是因为这是我完全陷入困境的地方，为完成 str＆＃39;＃＆＃39; 变量的所有细节工作做了一个循环进入体育词典可以拿起的东西，然后读作 {＆＃39; Curving＆＃39;：10}

在这里，我提供了目前正在使用并尝试简化的代码：

file = open('game_catch.txt','r')
line1 = file.readline()
line2 = file.readline()
line3 = file.readline()
line4 = file.readline()
line5 = file.readline()
line6 = file.readline()
line7 = file.readline()
line8 = file.readline()
line9 = file.readline()

str1 = line1.split()
str2 = line2.split()
str3 = line3.split()
str4 = line4.split()
str5 = line5.split()
str6 = line6.split()
str7 = line7.split()
str8 = line8.split()
str9 = line9.split()

sports = {}

key = ''
for i in str1[0:-1] :
    key += i + ' '

key = key[0:-1]

sports[key] = int(str1[-1])

很抱歉这篇长篇文章，我只想提供尽可能详细的信息。如果有更有效的方法，请随时告诉我。感谢

Answer 1

您可以通过迭代文件，分割每一行，并将该生成器中的对发送到@RunWith(PowerMockRunner.class) @PrepareForTest({ LocationAppDAO.class, BeanPropertyRowMapper.class }) public class CopyOfGeoLocationAppTest { @Autowired private ApplicationContext applicationContext; @Test @SuppressWarnings({ "unchecked" }) public void testJdbcTemplateforDbase() throws Exception { // LocationAppDAO locationAppdao= new LocationAppDAO(); String queryWgs84 = "SELECT * FROM location_wgs84 where latitude=" + 0 + " AND longitude=" + 0; LocationAppDAO locationAppDaoMock= EasyMock.createMock(LocationAppDAO.class); JdbcTemplate jdbcTemplateMock = EasyMock.createMock(JdbcTemplate.class); BeanPropertyRowMapper<Location_wgs84> beanPropertyRowMapperMock = EasyMock .createMock(BeanPropertyRowMapper.class); EasyMock.replay(beanPropertyRowMapperMock); // mocking location Location_wgs84 location_wgs84mock = EasyMock .createMock(Location_wgs84.class); location_wgs84mock.setLatitude(0); location_wgs84mock.setLongitude(0); EasyMock.replay(location_wgs84mock); PowerMock.expectNew(BeanPropertyRowMapper.class).andReturn( beanPropertyRowMapperMock); PowerMock.replayAll(); ArrayList<Location_wgs84> arrayList = new ArrayList<Location_wgs84>(); Location_wgs84 location1 = new Location_wgs84(); location1.setLatitude(1); location1.setLongitude(1); arrayList.add(location1); Location_wgs84 location2 = new Location_wgs84(); location2.setLatitude(2); location2.setLongitude(2); arrayList.add(location2); Location_wgs84 location3 = new Location_wgs84(); location3.setLatitude(3); location3.setLongitude(3); arrayList.add(location3); EasyMock.expect( jdbcTemplateMock.query(queryWgs84, beanPropertyRowMapperMock)) .andStubAnswer(new IAnswer<List<Location_wgs84>>() { @Override public List<Location_wgs84> answer() throws Throwable { return arrayList; }; }); EasyMock.replay(jdbcTemplateMock); EasyMock.expect( locationAppDaoMock.location_wgs84Query(0,0)) .andStubAnswer(new IAnswer<List<Location_wgs84>>() { @Override public List<Location_wgs84> answer() throws Throwable { return arrayList; }; }); EasyMock.replay(locationAppDaoMock); LocationAppDAO locationAppdao= new LocationAppDAO(); ReflectionTestUtils.setField(locationAppdao, "jdbcTemplate", jdbcTemplateMock); List<Location_wgs84> arrayListResult = locationAppdao.location_wgs84Query(0, 0); assertEquals(3.0, arrayListResult.get(2).getLatitude(), 0); EasyMock.verify(jdbcTemplateMock); } }来获得基本结构（将分数保持为字符串）：

dict()

您可以通过创建生成器来分割每一行，然后解压每一行并使用with open('game_catch.txt') as f: d = dict(line.rsplit(maxsplit=1) for line in f)函数来将分数转换为整数：

int()

您可以使用文字理解语法而不是with open('game_catch.txt') as f: d = dict((name, int(score)) for name, score in (line.rsplit(maxsplit=1) for line in f))函数：

dict()

当然，最重要的部分是查看教程，以便您可以了解这些代码片段的作用并理解解释。循环和数据结构尤为重要。

Answer 2

考虑到一些体育名称由多个单词组成，以下内容将把你的txt文件变成字典：

lines = [line.rstrip('\n').split() for line in open('C:/Users/Simon/Desktop/test.txt')]

sports = {}

for el in lines:
    number = el.pop()
    curItem = ' '.join(el)

    sports[curItem] = int(number)

print sports

这将是这样的：

{'Curving': 10, 'Keep Away': 5, 'Dodgeball': 15}

Answer 3

file = 'game_catch.txt'
sports = {}

with open(file) as f:
 for line in f:
  parts = line.split()
  sports[parts[0]] = int(parts[-1])

希望这会有所帮助。

Answer 4

示例

trans_dict = {＆＃39; one＆＃39;：＆＃39; wahed＆＃39;，＆＃39; two＆＃39;：＆＃39; itnen＆＃39;，＆＃39; three＆＃39; ：＆＃39;塔拉塔＆＃39;}

       print "ITER ITEMS", trans_dict.iteritems()

       for key, val in trans_dict.iteritems():

                   print "KEY", key

                   print "VAL", val

如何将变量添加到带循环的字典中？
