data2 = 'Wiki Loves Monuments (WLM) is an annual international photographic competition held during the month of September, organised worldwide by Wikipedia community members with the help of local Wikimedia affiliates across the globe. Participants take pictures of local historical monuments and heritage sites in their region, and upload them to Wikimedia Commons. The aim of event is to highlight the heritage sites of the participating countries with the goal to encourage people to capture pictures of these monuments, and to put them under a free licence which can then be re-used not only in Wikipedia but everywhere by everyone.\n\nThe first Wiki Loves Monuments competition was held in 2010 in the Netherlands as pilot project.

n = math.ceil(len(data2)/5000)
n = 5000
list2 = [data2[i:i+n] for i in range(0, len(data2), n)]
print(list2)
现在我需要在一个列表中包含大约5K字符，然后2列出另外5K字符，依此类推，最后一个列表包含所有剩余的字符。
输出：
[[[5K或更少字符]，[5K或更少字符]，... [剩余字符]]
从上面，我得到一个清单。另外，我正在寻找一种不会将句子分成两半而是整个句子的解决方案。
任何帮助表示赞赏。
谢谢
假设每个句子对应一行，可以执行以下操作：
text = ...
def special_split(text, limit=500):
chunks = []
chunk = ''
for line in text.splitlines():
if line: # gets rid of empty lines
if len(line) + len(chunk) < limit:
chunk += line + '\n'
else:
if chunk:
chunks.append(chunk)
chunk = line
if chunk:
chunks.append(chunk)
return chunks
chunks = special_split(text, 5000)
print(all(chunk < 5000 for chunk in chunks))
# True
请注意，如果单行大于指定的limit，则以上代码将失败。
要获得每个chunk作为list-len字符串（也称为字符）的1，您只需将其转换为list即可：
chunks_list = [list(chunk) for chunk in chunks]

如果我对您的理解正确，这听起来像textwrap.wrap的完美工作，它是标准python库的一部分。
from textwrap import wrap
long_string = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent tristique et urna sed pretium. In hac habitasse platea dictumst. Donec nulla mi, dapibus ac massa vel, elementum fermentum libero. Sed venenatis faucibus ex ut rutrum. In rutrum justo id nunc suscipit, eu ullamcorper nibh tincidunt. Vivamus posuere, ipsum eget dapibus rutrum, sapien est hendrerit elit, in commodo neque ex in sem. Mauris ac libero at velit vehicula egestas et nec metus. Phasellus bibendum pretium libero, id feugiat est ultrices eu. Maecenas quis nulla eu mi lacinia pellentesque."
segments = wrap(long_string, width=50)
for index, segment in enumerate(segments):
print(f"segment[{index}] (len == {len(segment)}): \"{segment}\"")
输出：

正如您从输出中看到的，段的长度不是完全固定的。这是因为textwrap.wrap默认情况下会考虑空格，并且不会创建会分割单词的新句段。但是，可以保证没有任何段会超出您指定的宽度。
您可能需要探索textwrap.TextWrapper类以适合您的需求。有关可选参数的完整列表，请查看documentation。
