In a setup.py script for a Python package, you can specify multiple authors and their corresponding email addresses using the author and author_email fields. You can provide this information as a list of strings. Here's an example of how to do it:
from setuptools import setup
setup(
name='your_package_name',
version='1.0.0',
description='Your package description',
author=['Author 1', 'Author 2'],
author_email=['[email protected]', '[email protected]'],
packages=['your_package'],
# ...
)
In this example:
We import the setup function from setuptools.
Inside the setup function, we specify the package name, version, description, and other relevant information.
For the author and author_email fields, we provide lists of author names and corresponding email addresses. You can add as many authors and email addresses as needed.
Using lists allows you to specify multiple authors and email addresses for your package. When you build or distribute your package, this information will be included in the package's metadata.
In a Python project's setup.py file, you can specify library versions by using the install_requires parameter in the setup() function. This allows you to specify the required versions or version ranges for your project's dependencies. Here's how you can do it:
from setuptools import setup
setup(
name="your_package_name",
version="0.1.0",
description="Your package description",
author="Your Name",
author_email="[email protected]",
packages=["your_package"],
install_requires=[
"dependency1==1.2.3", # Specify a fixed version
"dependency2>=2.0.0", # Specify a minimum version
"dependency3<=3.0.0", # Specify a maximum version
"dependency4~=4.1.0", # Use a compatible version specifier (e.g., >=4.1.0,<5.0.0)
],
classifiers=[
"Development Status :: 3 - Alpha",
"Intended Audience :: Developers",
"License :: OSI Approved :: MIT License",
"Programming Language :: Python :: 3",
"Programming Language :: Python :: 3.6",
"Programming Language :: Python :: 3.7",
"Programming Language :: Python :: 3.8",
"Programming Language :: Python :: 3.9",
],
)
In the install_requires list:
You can specify a fixed version using ==. For example, "dependency1==1.2.3" means your project requires exactly version 1.2.3 of dependency1.
You can specify a minimum version using >=. For example, "dependency2>=2.0.0" means your project requires at least version 2.0.0 of dependency2.
You can specify a maximum version using <=. For example, "dependency3<=3.0.0" means your project requires version 3.0.0 or earlier of dependency3.
You can use a compatible version specifier with ~=. For example, "dependency4~=4.1.0" means your project requires any version that is compatible with 4.1.0, which allows for bugfix updates but not breaking changes.
After specifying your dependencies and their versions in install_requires, you can use tools like pip or package managers like conda to install your project along with its dependencies, and the specified versions will be respected.
Remember to replace "your_package_name" with the actual name of your package and "your_package" with the name of your package's main module or package.
To specify Python 3 as the source for Cython in the setup.py file, you need to use the Python class provided by Cython's Distutils package. This class allows you to customize compilation options, including the target Python version.
Here's how you can specify Python 3 as the source in your setup.py file:
from distutils.core import setup
from Cython.Build import cythonize
from Cython.Distutils import build_ext
setup(
name="YourPackage",
ext_modules=cythonize("your_module.pyx", compiler_directives={"language_level": "3"}),
cmdclass={"build_ext": build_ext}
)
In this example, replace "your_module.pyx" with the path to your Cython source file.
The key part here is the compiler_directives parameter passed to the cythonize() function. Setting "language_level": "3" specifies that the code should be compiled for Python 3.
Remember to install Cython before running your setup.py script:
pip install cython
After installing Cython and setting up your setup.py file, you can build your Cython module for Python 3 by running:
python setup.py build_ext --inplace
This will generate the compiled Python extension module compatible with Python 3.
