我需要閱讀一個段落，我需要復制只有關鍵字的行。段落是這樣的：aaaaaaaaaaa[new,aaa] < name of the file with path ] //asabbsjkorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap[mod] <name of the file with path 我的算法：if keyword exists in the line : copy that line else: leave it

嘗試這幾行代碼：
copy_lines= []
for line in paragraph.split('\n'):
if keyword in line:
copy_lines.append(line)
print(copy_lines)
或一張內襯：
copy_lines= [line for line in paragraph.split('\n') if keyword in line]

如果您嘗試從文件中讀取該段落：
keyword = "your_keyword"
with open("demofile.txt", "r") as f:
line_list = f.readlines()
magic_lines = [line for line in line_list if keyword in line]
