我是一個Python初學者，我有很多很多關於它的問題。我試圖創建一個程序，我沒有完全得到結果。只有很少的計算在那裏，其餘的是印刷品。如何解決這個python程序中的錯誤？
它是這樣的：

縮進proper.The錯誤「totrate被分配之前引用的」我把它在全局變量是允許所有的地方，但仍當我犯規come.And得到結果的金額finrate沒有得到印刷。但沒有或0來。請讓我知道的錯誤。是否有東西我應該導入??對不起，麻煩，它爲一個類的演示文稿。 感謝您的努力。
縮進。 – Christian
請更正您的縮進，如果看起來像這樣，您的代碼肯定不會運行。 –
您的縮進是**不是**「正確的」。也許第一行和最後一行前面的空格在將代碼粘貼到您的問題中時是一個簡單的錯誤，但最後一個'else：'（在'print「無效」''之前）與代碼中的任何'if'都不匹配。縮進應該總是**每個級別四個空格;否則，你會錯過這樣的錯誤，並且你的代碼會讓其他人閱讀時感到痛苦（這意味着他們不想幫你調試它）。 –
