Python：IndexError：列表索引超出範圍

Question

我對python比較新。當我嘗試執行下面的代碼時，我收到了這個錯誤。我不明白這個錯誤。

def coinChange(S,m,n): 

    dp = [[0 for x in range(m)] for x in range(n+1)] 

    for i in range(m): 
     dp[0][i] = 1 

    for i in range(1,n+1): 
     for j in range(m): 
      if i >= S[j]: 
       dp[i][j] = dp[i-1][j] + dp[i][i-S[j]] 
      else: 
       dp[i][j] = dp[i-1][j] 

    return dp[i][j] 


S = [1,3,5] 
m = len(S) 
n = 11 

print(coinChange(S,m,n)) 



This is the error I'm getting: 
    Traceback (most recent call last): 
    File "C:\Users\SaiV\CoinChange.py", line 24, in <module> 
     print(coinChange(S,m,n)) 
    File "C:\Users\SaiV\CoinChange.py", line 13, in coinChange 
    dp[i][j] = dp[i-1][j] + dp[i][i-S[j]] 
    IndexError: list index out of range 

Answer 1

的錯誤意味着你已經嘗試檢索在不存在的列表（如my_list[index]）的指數值。這被認爲是明智的語言的致命錯誤，因此程序立即終止。閱讀其餘的例外信息，以更好地瞭解問題所在。
