如何在文本行之间添加空行。txt文件?

好的,对于200行长的文件,可以将整个文件存储为字符串列表,并在重新写入文件时添加行:

with open("text.txt", 'r') as f:
    data = [line for line in f]

with open("text.txt", 'w') as f:
    for line in data:
        f.write(line)
        f.write("Words between spacing\n")

您可以将此操作分为三个步骤。 list[str] 使用 f.readlines() :

with open("text.txt", "r") as f: # using "read" mode
    lines = f.readlines()

第二种方法是使用 "".join(...) 作用

lines = "My line between the lines\n".join(lines)

在第三步中,将其记录到文件中:

with open("text.txt", "w") as f: # using "write" mode
    f.write(lines)

此外,你可以使用 f.read() 结合 text.replace("\n", ...) :

with open("text.txt", "r") as f:
    full_text = f.read()

full_text = full_text.replace("\n", "\nMy desirable text between the lines\n")

with open("text.txt", "w") as f:
    f.write(full_text)

初始文本:

最后文本:

iushnaufihsnuesa
My desirable text between the lines
fsuhadnfuisgadnfuigasdf
My desirable text between the lines
asfhasndfusaugdf
My desirable text between the lines
