熊猫/ xlsxwriter writer.close（）无法完全关闭excel文件

标签： python excel pandas xlsxwriter sharing-violation

我正在尝试使用python脚本创建Excel文件后手动对其进行修改。不幸的是，如果脚本仍在运行，则尝试使用相同名称保存该脚本时会出现共享文件冲突错误消息。

一切都在代码中顺利运行。文件已创建，填充和保存。我可以打开它并对其进行处理，但是如果脚本仍在运行，则不能用相同的名称覆盖它。

outpath = filedialog.asksaveasfile(
    mode="wb",
    filetype=[("Excel", ("*.xls", "*.xlsx"))],
    defaultextension=".xlsx",
)
writer = pd.ExcelWriter(outpath, engine="xlsxwriter")
df1.to_excel(writer, sheet_name="Results")
writer.save()
writer.close()

我希望python能够完全关闭excel文件，并让我在脚本仍在运行时对其进行覆盖

我也有这个问题。 尝试在 Excel 中保存更改时，出现“共享冲突”。 解决了在 writer.handles = None 后添加 writer.close() 的问题。

writer = pd.ExcelWriter(workPath+'file.xlsx', engine='xlsxwriter')
# Add all your sheets and formatting here
...
# Save and release handle
writer.close()
writer.handles = None

您的代码看起来太复杂了，您不需要自己与df.to_excel()的作者打交道。 只需使用docs中建议的简单代码：df1.to_excel(outpath, sheet_name="Results", engine='xlsxwriter')。

我也遇到了这个。由于“共享冲突”，我无法将文件保存在 Excel 中，因为 python.exe 仍然拥有该文件的句柄。

接受的答案，如果您只想保存 Excel 文件，则仅使用 09-Jul-2021 15:59:49.016 SEVERE [http-nio-8080-exec-2] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [com.server.rest.JerseyResourceConfig] in context with path [/..] threw exception [java.lang.NullPointerException] with root cause java.lang.NullPointerException at com.server.rest.Restv1.demoApi(Restv1.java:83) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.glassfish.jersey.server.model.internal.ResourceMethodInvocationHandlerFactory.lambda$static$0(ResourceMethodInvocationHandlerFactory.java:52) at org.glassfish.jersey.server.model.internal.AbstractJavaResourceMethodDispatcher$1.run(AbstractJavaResourceMethodDispatcher.java:124) at org.glassfish.jersey.server.model.internal.AbstractJavaResourceMethodDispatcher.invoke(AbstractJavaResourceMethodDispatcher.java:167) at org.glassfish.jersey.server.model.internal.JavaResourceMethodDispatcherProvider$ResponseOutInvoker.doDispatch(JavaResourceMethodDispatcherProvider.java:176) at org.glassfish.jersey.server.model.internal.AbstractJavaResourceMethodDispatcher.dispatch(AbstractJavaResourceMethodDispatcher.java:79) at org.glassfish.jersey.server.model.ResourceMethodInvoker.invoke(ResourceMethodInvoker.java:475) at org.glassfish.jersey.server.model.ResourceMethodInvoker.apply(ResourceMethodInvoker.java:397) at org.glassfish.jersey.server.model.ResourceMethodInvoker.apply(ResourceMethodInvoker.java:81) at org.glassfish.jersey.server.ServerRuntime$1.run(ServerRuntime.java:255) at org.glassfish.jersey.internal.Errors$1.call(Errors.java:248) at org.glassfish.jersey.internal.Errors$1.call(Errors.java:244) at org.glassfish.jersey.internal.Errors.process(Errors.java:292) at org.glassfish.jersey.internal.Errors.process(Errors.java:274) at org.glassfish.jersey.internal.Errors.process(Errors.java:244) at org.glassfish.jersey.process.internal.RequestScope.runInScope(RequestScope.java:265) at org.glassfish.jersey.server.ServerRuntime.process(ServerRuntime.java:234) at org.glassfish.jersey.server.ApplicationHandler.handle(ApplicationHandler.java:680) at org.glassfish.jersey.servlet.WebComponent.serviceImpl(WebComponent.java:394) at org.glassfish.jersey.servlet.WebComponent.service(WebComponent.java:346) at org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:366) at org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:319) at org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:205) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:227) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:162) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:189) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:162) at com.server.HttpAuthFilter.doFilter(HttpAuthFilter.java:126) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:189) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:162) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:202) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:97) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:542) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:143) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:92) at org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:687) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:78) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:357) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:374) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:65) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:893) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1707) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.base/java.lang.Thread.run(Thread.java:834) 是正确的。但是如果你想做更多的事情，比如先给excel文件添加格式，你就必须使用df.to_excel()。

不过，正如 Exho 评论的那样，关键是您使用了表格：

pd.ExcelWriter()

您不要使用 with pd.ExcelWriter(outpath, engine="xlsxwriter") as writer: # do stuff here 或 writer.save()，它们无论如何都是同一个调用的同义词。相反，一旦您离开 writer.close() 范围，就会保存并关闭文件并释放句柄。

答案 3 :(得分：0)

我遇到了类似的情况。 alec_djinn 给出的建议不适用于多张纸，因为我正在工作。所以我只是忽略了 .close() 方法，它工作得很好。
