        # print new list with removed \n
        print fread(arguments['--file'])

Answer 1

字符串不可变，i.rstrip('\n') 返回一个新字符串。

使用列表理解：

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

或者，因为您正在将整个文件读入内存，str.splitlines()：

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

删除换行符不起作用
