这是一个一行的，可复制粘贴的解决方案，也关闭文件对象:

_ = open('data.txt', 'r'); data = _.read(); _.close()

with open("data.txt") as myfile:
    data="".join(line.rstrip() for line in myfile)

Join()将连接一个字符串列表，而不带参数的rstrip()将从字符串末尾删除空格，包括换行符。

要使用Python删除换行符，可以使用字符串的replace函数。

这个例子删除了所有3种类型的换行符:

my_string = open('lala.json').read()
print(my_string)

my_string = my_string.replace("\r","").replace("\n","")
print(my_string)

示例文件为:

{
  "lala": "lulu",
  "foo": "bar"
}

你可以尝试使用这个回放场景:

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()])

file = open("myfile.txt", "r")
lines = file.readlines()
str = ''                                     #string declaration

for i in range(len(lines)):
    str += lines[i].rstrip('\n') + ' '

print str

如此: 将文件更改为:

LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE

然后:

file = open("file.txt")
line = file.read()
words = line.split()

这将创建一个名为words的列表，等于:

['LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN', 'GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE']

去掉了"\n"。要回答括号阻碍你的问题，只需这样做:

for word in words: # Assuming words is the list above
    print word # Prints each word in file on a different line

Or:

print words[0] + ",", words[1] # Note that the "+" symbol indicates no spaces
#The comma not in parentheses indicates a space

这将返回:

LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN, GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE
