The changes If you use pip: pip install pywin32 --upgrade A number of things don't work via pip, so you may choose to install binaries - but you must choose both the correct Python version and "bittedness".
Compare these 2: Python 2. Assets 12 pywin Release To download pywin32 binaries you must choose both the correct Python version and "bittedness". A 32bit build will look something like Python 3.

The output directory may be changed from. By default, the subdirectory is named the same as the package, and without the -ExcludeVersion option this name will include the specific version installed. Inside the subdirectory is a tools directory that contains the Python installation:. In general, nuget packages are not upgradeable, and newer versions should be installed side-by-side and referenced using the full path. Alternatively, delete the package directory manually and install it again.
Many CI systems will do this automatically if they do not preserve files between builds. This contains a MSBuild properties file python. Including the settings will automatically use the headers and import libraries in your build. The package information pages on nuget. The embedded distribution is a ZIP file containing a minimal Python environment. It is intended for acting as part of another application, rather than being directly accessed by end-users.
The standard library is included as pre-compiled and optimized. The embedded distribution does not include the Microsoft C Runtime and it is the responsibility of the application installer to provide this.
Third-party packages should be installed by the application installer alongside the embedded distribution. Using pip to manage dependencies as for a regular Python installation is not supported with this distribution, though with some care it may be possible to include and use pip for automatic updates.
An application written in Python does not necessarily require users to be aware of that fact. The embedded distribution may be used in this case to include a private version of Python in an install package.
Depending on how transparent it should be or conversely, how professional it should appear , there are two options. Using a specialized executable as a launcher requires some coding, but provides the most transparent experience for users. With a customized launcher, there are no obvious indications that the program is running on Python: icons can be customized, company and version information can be specified, and file associations behave properly.
The simpler approach is to provide a batch file or generated shortcut that directly calls the python. In this case, the application will appear to be Python and not its actual name, and users may have trouble distinguishing it from other running Python processes or file associations.
With the latter approach, packages should be installed as directories alongside the Python executable to ensure they are available on the path.
With the specialized launcher, packages can be located in other locations as there is an opportunity to specify the search path before launching the application. Applications written in native code often require some form of scripting language, and the embedded Python distribution can be used for this purpose.
In general, the majority of the application is in native code, and some part will either invoke python. For either case, extracting the embedded distribution to a subdirectory of the application installation is sufficient to provide a loadable Python interpreter. As with the application use, packages can be installed to any location as there is an opportunity to specify search paths before initializing the interpreter.
Otherwise, there is no fundamental differences between using the embedded distribution and a regular installation. Besides the standard CPython distribution, there are modified packages including additional functionality. The following is a list of popular versions and their key features:. Popular scientific modules such as numpy, scipy and pandas and the conda package manager. Note that these packages may not include the latest versions of Python or other libraries, and are not maintained or supported by the core Python team.
To run Python conveniently from a command prompt, you might consider changing some default environment variables in Windows. If you regularly use multiple versions of Python, consider using the Python Launcher for Windows. Windows allows environment variables to be configured permanently at both the User level and the System level, or temporarily in a command prompt. To temporarily set environment variables, open Command Prompt and use the set command:. These changes will apply to any further commands executed in that console, and will be inherited by any applications started from the console.
Including the variable name within percent signs will expand to the existing value, allowing you to add your new value at either the start or the end. Modifying PATH by adding the directory containing python. In this dialog, you can add or modify User and System variables. To change System variables, you need non-restricted access to your machine i.
Administrator rights. Windows will concatenate User variables after System variables, which may cause unexpected results when modifying PATH. Besides using the automatically created start menu entry for the Python interpreter, you might want to start Python in the command prompt. The installer has an option to set that up for you. This allows you to type python to run the interpreter, and pip for the package installer.
Thus, you can also execute your scripts with command line options, see Command line documentation. You need to set your PATH environment variable to include the directory of your Python installation, delimited by a semicolon from other entries.
An example variable could look like this assuming the first two entries already existed :. Python uses it for the default encoding of text files e. If you have any Python 3. The filesystem encoding see PEP for details. The Python launcher for Windows is a utility which aids in locating and executing of different Python versions.
