如何在Python中的字符串中修剪/删除“ \ n”

Question

我有疑问。我是Python的新手

让我们说我有一个文件in.txt。在此文件中，我的名字如下所示。

Sunday

Monday

Tuesday
.
.

我想将它们放入列表，我在做

#!/usr/bin/python3
with open("in.txt") as f:
lines = f.readlines()
lines = [l for l in lines]
print (lines);

输出为：

['Sunday\n', 'Monday\n', 'Tuesday\n']

我想像这样打印它：

['Sunday', 'Monday', 'Tuesday']

我将如何删除\n

任何建议都会有很大帮助，我尝试rstrip()无效。

Answer 1

尝试一下：

lines = [l.strip() for l in lines]

Answer 2

它应该与rstrip()甚至strip()一起使用，就像这样：

with open("in.txt") as f:
    lines = f.readlines()

lines = [l.rstrip() for l in lines]
print (lines)

或更简洁地说：

with open("in.txt") as f: 
    lines = [line.rstrip() for line in f]

Answer 3

对rstrip使用列表理解：

with open("in.txt") as f:
    lines = [i.rstrip() for i in f]
print(lines)

输出：

['Sunday', 'Monday', 'Tuesday']
