在python的os.path中有一些函数,不知道哪个是你可以使用的:
- getatime( path)
- Return the time of last access of path. The return value is a number giving the number of seconds since the epoch (see the time module). Raise os.error if the file does not exist or is inaccessible. New in version 1.5.2. Changed in version 2.3: If os.stat_float_times() returns True, the result is a floating point number.
- getmtime( path)
- Return the time of last modification of path. The return value is a number giving the number of seconds since the epoch (see the time module). Raise os.error if the file does not exist or is inaccessible. New in version 1.5.2. Changed in version 2.3: If os.stat_float_times() returns True, the result is a floating point number.
- getctime( path)
- Return the system's ctime which, on some systems (like Unix) is the time of the last change, and, on others (like Windows), is the creation time for path. The return value is a number giving the number of seconds since the epoch (see the time module). Raise os.error if the file does not exist or is inaccessible. New in version 2.3.
