[ 1.1 ] 1. a electronic bill presentment system.
[ 1.2 ] a network.
[ 1.3 ] a plurality of first stations, each associated with a respective one of a plurality of users and operable to transmit first requests for bills of its associated user via the network.
[ 1.4 ] a central network station configured to receive the transmitted first requests for bills and to transmit, responsive to each of the received first requests, bill availability information for the associated user via the network, wherein each of the plurality of first stations is configured to receive the transmitted bill availability information for its associated user and is operable to transmit second requests for bills of its associated user via the network.
[ 1.5 ] a plurality of second network stations, each associated with a respective one of a plurality of billers, configured to receive the transmitted second requests for bills and to transmit, responsive thereto, the requested bills of the associated user via the network.
[ 1.6 ] wherein the bill availability information for the associated user identifies those of the plurality of billers having a bill available for that user without identifying an amount of the bill of each of the identified billers for the associated user.

您应该使用正则表达式用空字符串替换模式
>>> re.sub(r'\[\s?\d\.\d\s?]\s?(\d(\.\s)?)?', '', '[ 1.1 ] 1. a electronic bill presentment system.')
'a electronic bill presentment system.'

如果你不想避免使用正则表达式，只要你没有像
[1.2.b]def chop_non_alpha(txt):
for i in range(len(txt)):
if txt[i].isalpha():
return txt[i:]
for line in lines:
print(chop_non_alpha(line))

这看起来像一个课堂/作业问题。你熟悉正则表达式吗？是的，我知道正则表达式，但它不能使用。这看起来像是一个课堂/作业问题。你熟悉正则表达式吗？是的，我知道reg表达式，但它不能使用答案中所示的ITA，这不会删除前导1。在方括号之后。如答案所示，这不会删除前导1。在方括号之后。此链接是否自动创建Reg exp No，用于在样本字符串@RinkuYadavI上测试正则表达式。我对使用的量词很好奇。我将使用
+*\d？*1怎么办[1.1]1中的]
之后添加code>[1.1]+*\d？*1怎么办[1.1]1中的]
之后添加code>[1.1]
