mkdir for the Create Directory command in the Linux operating system, use the MKDIR-P directive to automatically create a parent directory that does not yet exist in the destination directory path (Windows operating systems also have instructions with the same name, with slightly different usage).
Mainly involves three functions
1, os.path.exists (path) to determine whether a directory exists
2. Os.makedirs (path) multi-layer Creation directory
3, Os.mkdir (path) to create a directory
Example
The code is as follows |
Copy Code |
def mkdir (path): # Introduce modules Import OS
# Remove First space Path=path.strip () # remove tail \ Symbol Path=path.rstrip ("\")
# to determine if a path exists # exists True # there is no False Isexists=os.path.exists (PATH)
# Judging Results If not isexists: # Create a directory if it doesn't exist Print path+ ' Create success ' # Create directory Action functions Os.makedirs (PATH) Return True Else # If the directory exists then do not create and hint that the directory already exists Print path+ ' directory already exists ' Return False
# define the directory to create Mkpath= "D:\\qttc\\web\\" # Call function mkdir (Mkpath) |
The above is a function that I wrote, only need to pass in you want to create the full path of the directory.
Description
In the above demo's function, I did not use the Os.mkdir (path) function, but used the Multi-layer creation directory function os.makedirs (path). The biggest difference between the two functions is that os.mkdir (path) is not created when the parent directory does not exist, and os.makedirs (path) creates the parent directory.
For example, the directory Web I want to create is located in the QTTC directory in D disk, but I do not have the QTTC parent directory under D disk, if using the Os.mkdir (path) function prompts me that the destination path does not exist, but uses os.makedirs (path) will automatically help me create the parent directory QTTC, please create the subdirectory Web in the QTTC directory.
The Java creation Directory has mkdir and mkdirs two methods, where:
For the Python 2.X (X > 2.5) version, the code that uses Python to simulate the mkdir-p instruction feature under Linux is as follows:
The code is as follows |
Copy Code |
Import OS, errno def mkdir_p (path): Try Os.makedirs (PATH) Except OSError as exc: # python >2.5 (except OSError, exc:for python <2.5) if Exc.errno = = errno. Eexist and Os.path.isdir (path): Pass Else:raise |
Instead of the Python 3.X (X >= 2) version, the Os.makedirs function also has a third argument EXIST_OK, which executes mkdir
-p When the argument is true, but if the mode argument is given, A OSError exception is thrown when the target directory already exists and is inconsistent with the directory permissions that will be created.
