Python open: FileNotFoundError: [Errno 2] No such file or directory

Python open函数在打开文件时出现FileNotFoundError: [Errno 2] No such file or directory的错误通常是由于文件路径不正确引起的。当Python无法找到指定路径下的文件时，就会抛出这个错误。要解决这个问题，有几个可能的原因和解决方法: 1. 检查文件路径是否正确: 首先，请确保你提供的文件路径是准确的。检查文件名是否正确拼写，并确保文件路径中的斜杠（/或\）是正确的。引用 2. 检查文件是否存在: 确保你要打开的文件实际上存在于指定路径中。你可以使用操作系统的文件浏览器或命令行工具来验证文件是否存在。 3. 检查文件权限: 如果文件存在但你没有足够的权限来访问它，也会导致该错误。确保你具有读取文件的权限。 4. 使用绝对路径: 如果你只提供了相对路径，尝试使用绝对路径来打开文件。这样可以确保Python能够准确找到文件。引用 5. 在打开文件之前检查文件是否存在: 使用`os.path.exists(file_path)`函数来检查文件是否存在，然后再尝试打开文件。这样可以避免抛出文件不存在的错误。引用总结，当出现Python open函数的FileNotFoundError: [Errno 2] No such file or directory错误时，你应该检查文件路径是否正确，文件是否存在以及你是否具有适当的权限来访问文件。如果问题仍然存在，可以尝试使用绝对路径或在打开文件之前检查文件是否存在来解决问题。123 #### 引用[.reference_title] - *1* [如何解决python.exe: can’t open file ‘manage.py’: [Errno 2] No such file or directory这个问题](https://download.csdn.net/download/weixin_38713099/13739420)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 33.333333333333336%"] - *2* [Python open: FileNotFoundError: [Errno 2] No such file or directory](https://blog.csdn.net/qq_36991505/article/details/102543109)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 33.333333333333336%"] - *3* [python使用with open语句保存文件时的路径问题及报错FileNotFoundError: [Errno 2] No such file or ...](https://blog.csdn.net/weixin_55579895/article/details/120353763)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 33.333333333333336%"] [ .reference_list ]
