Instructions
|
| basename(path) | Remove the directory path, file name alone returns |
| dirname(path) | Remove the file name, directory path returned alone |
| join(path1[, path2[, ...]]) | The path1, path2 departments packet combining a pathname |
| split(path) | Split the file name and path, return (f_path, f_name) tuples. If full use of the directory, it will also last a separate directory as the file name, and does not determine whether file or directory exists |
| splitext(path) | Separate file name and extension, return (f_name, f_extension) tuples |
| getsize(file) | Returns the specified file size in bytes |
| getatime(file) | Returns the most recent file access time (floating-point number of seconds, the available time module gmtime () or localtime () function conversion) |
| getctime(file) | Returns the creation time of the specified file (float number of seconds, the available time module gmtime () or localtime () function conversion) |
| getmtime(file) | Returns the latest file modification time (floating-point number of seconds, the available time module gmtime () or localtime () function conversion) |
|
The following is the function returns True or False
|
|
| exists(path) | Analyzing the specified path (file or directory) exists |
| isabs(path) | It determines whether the specified path is an absolute path |
| isdir(path) | Determining whether there is a specified path is a directory and |
| isfile(path) | And determining whether there is a specified path is a file |
| islink(path) | And the specified path is determined whether there is a symbolic link |
| ismount(path) | Determining whether there is a specified path is a mount point and the root directory |
