Question

我有一个根据列表字典创建的Pandas数据帧。我想在日期下拆分这些条目，并创建一个名为＆＃39; Story＆＃39;的新列。

                             2017-01-31           2017-02-01
 Gates, Bill.            [[SPGC-14075, 0.5]]                  [0]
 Jobs, Steve.            [[SPGC-14075, 3.5]]                  [0]
 Jobs, Steve.             [[SPGC-9456, 2.5]]                  [0]
 White, John ANDERSON.  [[SPGC-14075, 1.75]]  [[SPGC-9456, 5.25]]

理想输出：

                         Story            2017-01-31    2017-02-01
 Gates, Bill.           SPGC-14075         0.5                   0
 Jobs, Steve.           SPGC-14075         3.5                   0
 Jobs, Steve.           SPGC-94562          .5                   0
 White, John ANDERSON.  SPGC-14075        1.75                   0
 White, John ANDERSON.  SPGC-9456            0                   5.25

如何使用pandas数据帧操作进行此操作？

编辑：

使用nanojohn的解决方案我得到了这个输出。很接近了。仍需要打破2017-02-01中的最后一个条目。

                       2017-01-31         2017-02-01       Story
Gates, Bill.                 0.50                  0  SPGC-14075
Jobs, Steve.                 3.50                  0  SPGC-14075
Jobs, Steve.                 2.50                  0   SPGC-9456
White, John ANDERSON.        1.75  [SPGC-9456, 5.25]  SPGC-14075

您可以尝试使用WARNING: TestEngine with ID 'junit-jupiter' failed to discover tests java.lang.NoSuchMethodError: org.junit.platform.engine.TestDescriptor.pruneTree()V Aug 02, 2017 2:44:56 PM org.junit.platform.launcher.core.DefaultLauncher handleThrowable WARNING: TestEngine with ID 'junit-vintage' failed to discover tests java.lang.NoSuchMethodError: org.junit.platform.engine.EngineDiscoveryRequest.getDiscoveryFiltersByType(Ljava/lang/Class;)Ljava/util/List; Aug 02, 2017 2:44:56 PM org.junit.platform.launcher.core.DefaultLauncher handleThrowable WARNING: TestEngine with ID 'junit-jupiter' failed to discover tests java.lang.NoSuchMethodError: org.junit.platform.engine.TestDescriptor.pruneTree()V Aug 02, 2017 2:44:56 PM org.junit.platform.launcher.core.DefaultLauncher handleThrowable WARNING: TestEngine with ID 'junit-vintage' failed to discover tests java.lang.NoSuchMethodError: org.junit.platform.engine.EngineDiscoveryRequest.getDiscoveryFiltersByType(Ljava/lang/Class;)Ljava/util/List;方法，如下所示（假设您的DataFrame位于名为.apply()的变量中）：
