pandas-快速读/写同一csv。获取权限错误

由于您不共享确切的代码,我们只能假设您存储的数据帧如下:

df.to_csv("myfile.csv", sep = ",", index = False)    # Drop to csv w/o context manager

在这种情况下,您遇到的行为是由于文件未正确关闭。这是一个常见的错误。我建议使用 with - statement ,其主要用途是对内部使用的对象进行异常安全清理(在本例中 .csv )换句话说, 具有 确保关闭文件、释放锁、还原上下文等。

with open("myfile.csv", "w") as reference:           # Drop to csv w/ context manager
     df.to_csv(reference, sep = ",", index = False)
# As soon as you are here, reference is closed

关闭要读写的文件,然后尝试运行脚本。 希望有帮助
