Python字符串条带而不是条带换行符

Question

我不能去掉空格和换行符。你知道哪里出了问题吗?

    line_count = 0
    word_count = 0
    for fline in fh:
        line = repr(fline)
        line = line.strip()
        print line
        line_count += 1
        word_count += len(line.split())
    result['size'] = filesize
    result['line'] = line_count
    result['words'] = word_count

输出

'value of $input if it isn'
' larger than or equal to ygjhgn'
' that number. Otherwise assigns the value of n'
' n'
' '

Answer 1

由于repr():

您的字符串被双引号包围

>>> x = 'hellon'
>>> repr(x)
"'hello\n'"
>>> repr(x).strip()
"'hello\n'"
>>> 

这是你编辑的代码:

line_count = 0
word_count = 0
for fline in fh:
    line = repr(line.strip())
    print line
    line_count += 1
    word_count += len(line.split())
result['size'] = filesize
result['line'] = line_count
result['words'] = word_count

Answer 2

如果fline是一个字符串，那么用它作为参数调用repr将把它括在字面引号中。因此:

foon

是

"foon"

由于换行符不再位于字符串的末尾，strip将不会删除它。也许可以考虑不调用repr，除非你迫切需要，或者在调用strip后调用。

Answer 3

从别人提到的，只要改变

    line = repr(fline)
    line = line.strip()

    line = line.strip()
    line = repr(fline)

请注意，您可能需要.rstrip()甚至.rstrip("n")。
