命令行启动模块的Python代码研究

pyrasite的

__requires__ = 'pyrasite==2.0' import re import sys from pkg_resources import load_entry_point if __name__ == '__main__': sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0]) sys.exit( load_entry_point('pyrasite==2.0', 'console_scripts', 'pyrasite')() )

mitmproxy的

import re import sys from mitmproxy.tools.main import mitmproxy if __name__ == '__main__': sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0]) sys.exit(mitmproxy())

Ipython的

import re import sys from IPython import start_ipython if __name__ == '__main__': sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0]) sys.exit(start_ipython())

pip3的

import re import sys from pip._internal import main if __name__ == '__main__': sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0]) sys.exit(main())

virtualenv的

import re import sys from virtualenv import main if __name__ == '__main__': sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0]) sys.exit(main())

看完大概就能知道命令行模式启动的原理了。
