python要支持多行字符串输入，要怎么写？ python3 怎么读入多行字符串。

stopword = ''str = ''for line in iter(input, stopword): str += line + '\n'\u8fd9\u6837\u5c31\u53ef\u4ee5\u4e86\uff0c\u76f4\u5230\u4f60\u8f93\u5165\u7a7a\u767d\u884c\u624d\u4f1a\u505c\u6b62
第一个问题，多行字符串用三个引号，当然在非赋值的情况下三个引号表示是注释。。
第二个问题，你可以按行将字符串分割然后输出。
str = """First
Second
Third"""
a = str.split("
")
for i in xrange(len(a)):
print a[i] + ": " + str(i)
