When the command is a shell built-in, add a shell=True to the call. E.g. for dir you would type: import subprocess subprocess.call(‘dir’, shell=True) To quote from the documentation: The only time you need to specify shell=True on Windows is when the command you wish to execute is built into the shell (e.g. dir or copy). … Read more
I believe it’s in C:\Windows\System32\WindowsPowershell\v1.0\. In order to confuse the innocent, MS kept it in a directory labeled “v1.0”. Running this on Windows 7 and checking the version number via $Host.Version (Determine installed PowerShell version) shows it’s 2.0. Another option is type $PSVersionTable at the command prompt. If you are running v2.0, the output will … Read more
Access to the path ‘C:\inetpub\wwwroot\mysite\images\savehere’ is denied Read the message carefully. You are trying to save to a file that has the same name as the directory. That cannot work, you can’t overwrite a directory filled with files with a single new file. That would cause undiagnosable data loss, “Access to the path is denied” … Read more
you can use always: ‘C:/mydir’ this works both in linux and windows. Other posibility is ‘C:\\mydir’ if you have problems with some names you can also try raw string literals: r’C:\mydir’ however best practice is to use the os.path module functions that always select the correct configuration for your OS: os.path.join(mydir, myfile) From python 3.4 … Read more
You may not have set your PATH correctly to point at your Git installation. You need to add the following paths to PATH: C:\Program Files\Git\bin\ C:\Program Files\Git\cmd\ And check that these paths are correct. You may have Git installed on a different drive, or under Program Files (x86). Correct the paths if necessary. Modifying PATH … Read more
There are a couple of ways: pathlib.Path().rglob() Use pathlib.Path().rglob() from the pathlib module, which was introduced in Python 3.5. from pathlib import Path for path in Path(‘src’).rglob(‘*.c’): print(path.name) glob.glob() If you don’t want to use pathlib, use glob.glob(): from glob import glob for filename in glob(‘src/**/*.c’, recursive=True): print(filename) For cases where matching files beginning with … Read more
On Python ≥ 3.5, use pathlib.Path.mkdir: from pathlib import Path Path(“/my/directory”).mkdir(parents=True, exist_ok=True) For older versions of Python, I see two answers with good qualities, each with a small flaw, so I will give my take on it: Try os.path.exists, and consider os.makedirs for the creation. import os if not os.path.exists(directory): os.makedirs(directory) As noted in comments … Read more
The approach of using __dirname is the most reliable one. It will always give you correct directory. You do not have to worry about ../../ in Windows environment as path.join() will take care of that. There is an alternative solution though. You can use process.cwd() which returns the current working directory of the process. That … Read more
Type setx /? to get basic command help. You’ll easily discover: /M Specifies that the variable should be set in the system wide (HKEY_LOCAL_MACHINE) environment. The default is to set the variable under the HKEY_CURRENT_USER environment. You need to run this from an elevated command prompt. Right-click the cmd shortcut and select Run as Administrator. … Read more
