```如題，以下為我的程式碼，想請問第27行為什麼即使我input 為1，但輸出出來他卻說index error(下面print true 跟print bad是我先隨意打的一個指令）
ex. 我inpiut輸入：i 1 ryan 90 1 之後輸入pm 這時卻跳出index error 並告訴我 line 27: index out of range![https://ithelp.ithome.com.tw/upload/images/20210531/20137974n5HFGMhlgQ.png](https://ithelp.ithome.com.tw/upload/images/20210531/20137974n5HFGMhlgQ.png)
