Question

我在python中遇到了这个循环的问题：

i = 1
while True:
    with open('/tmp/file.txt', 'r+') as f:
        for line in f:
            work = 'word1' + line + 'word2' + line + 'counter=' + str(i) + 'test'
            result = Function()
            if "statement" in result:
                out = open('/tmp/result.txt', 'a+')
                out.write(result)
                out.close()
                i = i + 10
            else:
                return i

我想先逐行读取file.txt，然后逐行读取每个行数i，直到语句存在于结果中，但这个循环是不定式的......所以我删除了break并使用了{{1相反。但没有结果

当读取file.txt中的所有行并且每个行计数器完成时，如何判断True循环何时停止？

我想要处理的内容：

return i

我认为你需要切换你的循环：

i = 1
with open('/tmp/file.txt', 'r+') as f:
    for line in f:
        result = ...
        while "statement" in result:
            with open('/tmp/result.txt', 'a+') as out:
                out.write(result)
            i += 10
            result = ...

虽然目前还不清楚这个算法应该做什么

我找到了答案：

out = open('/tmp/result.txt', 'a+')
with open('/tmp/file.txt', 'r+') as f:
        for line in f:
                i = 1
                line=line.strip('\r\n ')
                while True:
                        work = 'word1' + line + 'word2' + line + 'counter=' + str(i) + 'test'
                        print work
                        result = Function()
                        if "statement" in result:
                                out.write(result)
                                i += 10
                        else:
                                break
out.close()

而python中的真正循环无法停止
