![]() Use Python.import to import a Python module. Let pythonRange: PythonObject = PythonObject(5.(pythonRange)! Let pythonString: PythonObject = "Hello Python!" Convert standard Swift types to Python. PythonObject defines many standard operations, including numeric operations, indexing, and iteration. To explicitly cast a Swift value to PythonObject, use the PythonObject initializer. In some cases (for literals and functions taking PythonConvertible arguments), conversion happens implicitly. In Swift, PythonObject represents an object from Python.Īll Python APIs use and return PythonObject instances.īasic types in Swift (like numbers and arrays) are convertible to PythonObject. Set PYTHON_LOADER_LOGGING=1 to see debug output for Python library loading. It cannot be used to dynamically switch Python versions. Note: you should run eVersion right after import Python, before calling any Python code. In code, you can also call the eVersion function, which is equivalent to setting PYTHON_VERSION. Note that PYTHON_LIBRARY takes precedence over PYTHON_VERSION. The exact filename will differ across Python environments and platforms.Īlternatively, you can set the PYTHON_VERSION environment variable, which instructs Swift to search system library paths for a matching Python version. ![]() ![]() For example:Įxport PYTHON_LIBRARY="~/anaconda3/lib/libpython3.7m.so" To use a specific Python installation, set the PYTHON_LIBRARY environment variable to the libpython shared library provided by the installation. import PythonKitīy default, when you import Python, Swift searches system library paths for the newest version of Python installed. You can import Python modules from Swift, call Python functions, and convert values between Swift and Python. Swift For TensorFlow supports Python interoperability. ![]()
