新人求助关于python-docx的问题

from docx import Document

doc = Document('test.docx')
name = str(input('请输入'))
IDcard = str(input('请输入'))
paragraph3 = doc.paragraphs

paragraph3.add_run(name).underline = True
paragraph3.add_run(IDcard).underline = True

paragraph3.runs = paragraph3.runs
paragraph3.runs = paragraph3.runs

paragraph3.runs.clear()
paragraph3.runs.clear()

doc.save('new.docx')

大佬们，为什么我这段代码创建了新的文档后和原文档一样呢
我想把paragraph3.runs的内容替换为paragraph3.runs的内容
为什么不能用 = 呢

paragraph3.runs = paragraph3.runs 这一句相当于将 paragraph3.runs 指向 paragraph3.runs ，它们都是指向同一个数据，所以对其中一个执行了 clear()，另外一个也会被 clear()

doc.paragraphs.text = doc.paragraphs.text

doc.paragraphs.clear()
doc.paragraphs.clear()

doc.save('new.docx')
