File¶
-
pydu.file.
makedirs
(path, mode=0o755, ignore_errors=False, exist_ok=False)¶ Based on
os.makedirs
,create a leaf directory and all intermediate ones.mode
default is0o755
. When make an exists path, if exist_ok is false,makedirs
will raise anException
. Ifignore_errors
which will ignore all errors raised byos.makedirs
.>>> from pydu.file import makedirs >>> makedirs('test1/test2') >>> makedirs('test1',exist_ok=True) >>> makedirs('test1') Traceback (most recent call last): ... OSError: Create dir: test1 error.
-
pydu.file.
remove
(path, mode=0o755, ignore_errors=False, onerror)¶ Remove a file or directory.
If
ignore_errors
is set, errors are ignored; otherwise, if onerror is set, it is called to handle the error with arguments (func , path , exc_info ) where func is platform and implementation dependent; path is the argument to that function that caused it to fail; and exc_info is a tuple returned by sys.exc_info(). If ignore_errors is False and onerror is None, an exception is raised.>>> from pydu.file import makedirs >>> from pydu.file import remove >>> from pydu.file import open_file >>> makedirs('test1') >>> remove('test1') >>> open_file('test.txt') >>> remove('test.txt') >>> remove('test',ignore_errors=True) >>> remove('test') Traceback (most recent call last): ... OSError: Remove path: test error
-
pydu.file.
removes
(paths, mode=0o755, ignore_errors=False, onerror)¶ Remove a list of file and/or directory.Other parameters same as remove.
>>> from pydu.file import makedirs >>> from pydu.file import remove >>> from pydu.file import open_file >>> makedirs('test1') >>> makedirs('test2') >>> open_file('test.txt') >>> removes(['test.txt','test1','test2'])
-
pydu.file.open_file(path, mode='wb+', buffer_size=-1, ignore_errors=False):
Open a file, defualt mode
wb+
. If path not exists, it will be created automatically. Ifignore_errors
is set, errors are ignored.>>> from pydu.file import open_file >>> open_file('test.txt') >>> ls test.txt >>> open_file('test1.txt',mode='r') Traceback (most recent call last): ... OSError: Open file: test1.txt error
-
pydu.file.copy(src, dst, ignore_errors=False, follow_symlinks=True):
Copy data and mode bits (cp src dst).Both the source and destination may be a directory.When copy a directory,which contains a symlink,if the optional symlinks flag is true, symbolic links in the source tree result in symbolic links in the destination tree; if it is false, the contents of the files pointed to by symbolic links are copied.When copy a file,if follow_symlinks is false and src is a symbolic link, a new symlink will be created instead of copying the file it points to,else the contents of the file pointed to by symbolic links is copied.
>>> from pydu.file import copy,symlink >>> from pydu.file import makedirs,open_fle >>> open_fle('test/test.txt') >>> symlink('test/test.txt','test/test.link') >>> copy('test/test.link','test/test_copy1.link') >>> copy('test/test.link','test/test_copy2.link',follow_symlink=False)
-
pydu.file.touch(path):
Open a file as write,and then close it.
>>> from pydu.file import touch >>> touch('test.txt')
-
pydu.file.
symlink
(src, dst, overwrite=False, ignore_errors=False)¶ symlink
only work on Unix-like system, it create a symbolic link pointing to source named link_name.If dist is exist and overwrite is true,a new symlink will be created.>>> from pydu.file import symlink >>> symlink('test.txt','test.link')
Note
symlink
can only be used onunix-like
system.
-
pydu.file.link(src, dst, overwrite=False, ignore_errors=False):
link
only work on Unix-like system, it create a hard link pointing to source named link_name.If dist is exist and overwrite is true,a new link will be created.>>> from pydu.file import link >>> link('test.txt','test.link')
Note
link
can only be used onunix-like
system.
