- version(): operating system version
- release(): operating system release number, for example, win 7 returns 7, and NT, 2.2.0, etc.
- platform(aliased=0, terse=0): operating system information string, combined with system()+win32_ver()[:3]
- win32_ver(release='', version='', csd='', ptype=''): win system related information
- linux_distribution(distname='', version='', id='', supported_dists=('SuSE', 'debiaare', 'yellowdog', 'gentoo', 'UnitedLinux', 'turbolinux'), full_distribution_name= 1): Linux system related information
- dist(distname='', version='', id='', supported_dists=('SuSE', 'debian', 'fedora', 'redhat', 'centos', 'mandrake', 'mandriva' , 'rocks', 'slackware', 'yellowdog', 'gentoo', 'UnitedLinux', 'turbolinux')): Try to obtain Linux OS release version information. Return (distname, version, id). dist means release version .
- mac_ver(release='', versioninfo=('', '', ''), machine=''): mac version
- java_ver(release='', vendor='', vminfo=('', '', ''), osinfo=('', '', '')): java version
- libc_ver(executable=r'c:Python27python.exe', lib='', version='', chunksize=2048): libc version, Linux related.
The returned tuple of the above corresponding version query corresponds to its formal parameters.

Is the vscode extension malicious?
Apr 15, 2025 pm 07:57 PM
VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.
How to run programs in terminal vscode

In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.
Can vs code run in Windows 8
Apr 15, 2025 pm 07:24 PM
VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.
