这里有四个代码供您选择:

with open("my_text_file.txt", "r") as file:
    data = file.read().replace("\n", "")

or

with open("my_text_file.txt", "r") as file:
    data = "".join(file.read().split("\n"))

or

with open("my_text_file.txt", "r") as file:
    data = "".join(file.splitlines())

or

with open("my_text_file.txt", "r") as file:
    data = "".join([line for line in file])

from pathlib import Path   
line_lst = Path("to/the/file.txt").read_text().splitlines()

是获取文件所有行的最佳方法，'\n'已经被splitlines()剥离(它可以智能识别win/mac/unix行类型)。

但如果你想剥离每一行:

line_lst = [line.strip() for line in txt = Path("to/the/file.txt").read_text().splitlines()]

Strip()只是一个有用的示例，但是您可以按照自己的意愿处理您的行。

最后，你只想要连接的文本?

txt = ''.join(Path("to/the/file.txt").read_text().splitlines())

在Python 3.5或更高版本中，使用pathlib可以将文本文件内容复制到一个变量中，并在一行中关闭文件:

from pathlib import Path
txt = Path('data.txt').read_text()

然后你可以使用str.replace删除换行符:

txt = txt.replace('\n', '')

很难确切地说出你在追求什么，但像这样的东西应该让你开始:

with open ("data.txt", "r") as myfile:
    data = ' '.join([line.replace('\n', '') for line in myfile.readlines()])

试试下面的方法:

with open('data.txt', 'r') as myfile:
    data = myfile.read()

    sentences = data.split('\\n')
    for sentence in sentences:
        print(sentence)

注意:不移除\n。它只是为了查看文本，就像没有\n一样

f = open('data.txt','r')
string = ""
while 1:
    line = f.readline()
    if not line:break
    string += line

f.close()


print(string)
