Is it possible to make a Python program which checks if a file exists, maybe like:

• Vbs Check If Folder Exists
• Check If Folder Exists Python
• C# Check If Folder Exists

There is a chance that you can learn whether the folder exists implicitly from an attempt to use it. If you expect it to exist and be writable to you, then create a temporary file there and if the that succeeds, the folder exists. If it fails, you might not be able to distinguish a non-existent folder from insufficient permissions, of course. DIR returns a string that represents a directory or file that matches a defined pattern. For example, with the DIR function you can check if a specific Excel file exists and then open it in the background, and copy and paste data into the active workbook. You can also check if a folder exists, if it doesn’t, create a new folder in the directory. For example below, when a button Command2 is clicked, program will looking for folder “Math1” under the C: Dropbox. If there is no such C: Dropbox Math1 folder/path then it will create the Math1 folder under C: Dropbox folder. If the folder already exists then the message “This folder already exists.” will pop-up. Robust Programming. When you process user-specified path strings, you should also handle exceptions for the following conditions: The file name is malformed. For example, it contains invalid characters or only white space. The file name is null. The file name is longer than the system-defined maximum length. The file name contains a colon (:).

I would like to be able to detect when a Windows Explorer folder or file is selected without having to 'poll' for changes. This could take either of 2 forms that occur to me: 1) Run a shell extension similar to a context menu or property sheet handler, but immediately on file or folder selection.

Obviously the if exist code will fail, as it is not a python command, but is there anything like the above which works?

Vbs Check If Folder Exists

Recommended Answers

Look at os.path.exists and os.path.isfile thats dos what you describe.

HiHe function is ok,but some changes that i think make it better.
Bare except(catch all maybe) i dont like this to much.
And with open() is preferred over open(),no need to close file object and it dos some error checking to.

Or try/except that is a safe an pythonic way to solve this.
