这里可以用list替换set么
months = set(['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']) x1 = 'Feb' x2 = 'Sun' if x1 in months: print 'x1: ok' else: print 'x1: error' if x2 in months: print 'x2: ok' else: print 'x2: error'
months = set(['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']) x1 = 'Feb' x2 = 'Sun' if x1 in months: print 'x1: ok' else: print 'x1: error' if x2 in months: print 'x2: ok' else: print 'x2: error'
