从一个文本文件删除换行符

Question

假设我有一个文本文件(test.txt):

This is a 
test

我的python代码:

f = open("test.txt")
x = f.readlines()
s = []
for i in x:
k = i.replace("a","not a")
s.append(k)
with open('output.txt', 'w') as a:
a.write("  ".join(s))

给出如下(output.txt):

This is not a 

test

，但我不想要中间的空格。我想要这样写:

This is not a test

如何删除换行符?

Answer 1

立即连接每一行，然后用空白分隔整个字符串。然后你应该有可以循环和替换的单词，然后再连接在一起

replacements = {"a" : "not a"} 
def replace(s):
if s in replacements:
return replacements[s]
return s
with open("test.txt") as f:
x = " ".join(l.strip() for l in f)
x = x.split()
print(" ".join(replace(s) for s in x))
