顶顶大名的Guido van Rossum(Python之父)推荐的main写法: #!/usr/bin/python import sys import getopt class Usage(Exception): def __init__(self, msg): self.msg = msg def main(argv=None): if argv is None: argv = sys.argv try: try: opts, args = getopt.getopt(argv[1:], "h", ["h...
if __name__ == "__main__": main(sys.argv[1:]) ``` 在这个例子中,main函数接收命令行参数,通过sys.argv获取参数列表并传递给main函数。 总结而言,main函数在Python中是一种良好编程习惯的体现,通过合理使用main函数,我们可以编写出结构清晰、易于维护的代码。
