我认为创建匿名函数的困难有点让人头疼。您真正想要做的是将相关代码保持在一起，并使代码整齐。因此，我认为装饰师可能会为您工作。
import re# List of pairs (regexp, handler)handlers = []def handler_for(regexp): """Declare a function as handler for a regular expression.""" def gethandler(f): handlers.append((re.compile(regexp), f)) return f return gethandler@handler_for(r'^<w+> (.*)')def handle_message(msg): print msg@handler_for(r'^*{3} (.*)')def handle_warning(msg): global num_warnings, num_fatals num_warnings += 1 if is_fatal(msg): num_fatals += 1
