删除换行符不起作用

我试图从函数中创建的列表中删除\n。我的代码去除它似乎没有工作。我没有得到一个错误？

Answer 1

字符串是不可变的，i.rstrip('\n')回报一个新的字符串。

使用列表理解：

def fread(dwords): 
    flist = open(dwords).readlines() 
    return [s.rstrip('\n') for s in flist] 

，或者因为你正在阅读的整个文件到内存反正str.splitlines()：

def fread(dwords): 
    return open(dwords).read().splitlines()
