Question

我的for循环的开头是返回错误。所有缩进都使用制表符完成。我已经检查过，没有空格与标签混合。

修改的我正在编辑为每个请求包含整个代码，因为看起来错误不在第29行的for循环中，尽管这是错误指向的地方。如前所述，我检查确保所有缩进都是制表符，而不是空格。作为一项额外措施，我使用Sublime的功能将缩进转换为制表符。我也将它转换为4个空格，但我仍然得到同样的错误。

Answer 1

Traceback (most recent call last):
  File "../indent.py", line 40, in <module>
    quizFile.write('%s. What is the capital of %s?\n') % (questionNum + 1, states[questionNum])
TypeError: unsupported operand type(s) for %: 'int' and 'tuple'

现在，显示的行中的问题是您正在尝试编写文字格式字符串：

quizFile.write('%s. What is the capital of %s?\n')

是一个完整的表达式：它写入该字符串，其中包含%个字符，并返回写入的字节数。这意味着该行的其余部分评估为

(bytes written)  % (questionNum + 1, states[questionNum])

这意味着你有一个int作为左手参数，一个元组作为%的右硬参数。这就是例外情况。

该行应为：

quizFile.write('%d. What is the capital of %s?\n' % (questionNum + 1, states[questionNum]))

请注意'format' % (tuple)表达式全部位于write(...)。

内

Answer 2

您似乎忘了缩进quizFile.write('\n\n')。或者在它之后添加错误的ident。在它没有意义之后的同一性，该代码不能在上面定义的循环中继续。

虽然缩进似乎是一致的，但没有混合的空格/制表符，Python代码会保持返回意外的缩进错误
