推荐答案

可以像创建任何其他文件一样创建空的 csv 文件 - 您只需对其执行任何操作.使用 bash，您可以执行 touch/path/to/my/file.csv.

An empty csv file can be created like any other file - you just have to perform any operation on it. With bash, you can do touch /path/to/my/file.csv.

请注意，您不必为要写入的 Python 创建一个空文件.如果您写入一个不存在的文件，Python 将自动执行此操作.实际上，从python内部创建一个空文件意味着打开它进行写入，但不向其中写入任何内容.

Note that you do not have to create an empty file for python to write in. Python will do so automatically if you write to a non-existing file. In fact, creating an empty file from within python means to open it for writing, but not writing anything to it.

with open("foo.csv", "w") as my_empty_csv:
  # now you have an empty file already
  pass  # or write something to it already
