我正在尝试使用 help()
函数查看 Python Idle 中的文件处理函数文档。
到目前为止,我已经完成并得到了以下内容:
>>> fh = open('file.txt', 'w')
>>> help(fh.seek)
Help on built-in function seek:
seek(...)
如何获取文档?
最佳答案
>>> import io
>>> help(io.FileIO.seek)
返回:
Help on method_descriptor:
seek(...)
seek(offset: int[, whence: int]) -> None. Move to new file position.
Argument offset is a byte count. Optional argument whence defaults to
0 (offset from start of file, offset should be >= 0); other values are 1
(move relative to current position, positive or negative), and 2 (move
relative to end of file, usually negative, although many platforms allow
seeking beyond the end of a file).
Note that not all file objects are seekable.
