时就找到字符串索引。
我正在使用"PO 00000"
但是它给了我findPageNum = [m.start() for m in re.finditer(pageNum, noNewLine)]开始后20个字符的值。
这是我的代码。
"PO 00000"输出为# -*- coding: utf-8 -*-

As we consider this bill, we anticipate that amendments addressing Russia "
"sanctions are likely to be offered.

Our many levees, docks, and dams represent crucial infrastructure that play an important role in our regional and national economy. I am proud "
"of the work Congress has done in the past to protect our Nation’s waterways, like passing the Water Resources Development Act by a bipartisan majority last year in order to support infrastructure, enhance commerce, and maintain American ecosystems.

您似乎认为您使用的是Python 3，但您使用的是Python2。（无论如何，您正在编写print调用，就像您认为自己使用的是Python 3。）
在Python 2上，您的字符串是一个字节字符串，而您正在使用一个字节字符串正则表达式。所有索引都是按字节而不是字符。您的字节字符串包含Unicode字符以外的Unicode字符的多字节UTF-8编码，从而导致索引与您期望的值不同。
获取Python 3。
