我試圖在 Python 上迭代一個多維陣列，但我遇到了問題，因為我的陣列充滿了資料幀而不是 int()。
我有一個多維 numpy 陣列 (12, 11)，其中包含 12 x 11 個不同的資料幀。
nombres_df = np.array([[df_01_ID4034, df_02_ID4034, df_03_ID4034, df_04_ID4034, df_05_ID4034, df_06_ID4034, df_07_ID4034, df_08_ID4034, df_09_ID4034, df_10_ID4034, df_11_ID4034, df_12_ID4034],
[df_01_ID4035, df_02_ID4035, df_03_ID4035, df_04_ID4035, df_05_ID4035, df_06_ID4035, df_07_ID4035, df_08_ID4035, df_09_ID4035, df_10_ID4035, df_11_ID4035, df_12_ID4035],
[df_01_ID4039, df_02_ID4039, df_03_ID4039, df_04_ID4039, df_05_ID4039, df_06_ID4039, df_07_ID4039, df_08_ID4039, df_09_ID4039, df_10_ID4039, df_11_ID4039, df_12_ID4039],
[df_01_ID4040, df_02_ID4040, df_03_ID4040, df_04_ID4040, df_05_ID4040, df_06_ID4040, df_07_ID4040, df_08_ID4040, df_09_ID4040, df_10_ID4040, df_11_ID4040, df_12_ID4040],
[df_01_ID4041, df_02_ID4041, df_03_ID4041, df_04_ID4041, df_05_ID4041, df_06_ID4041, df_07_ID4041, df_08_ID4041, df_09_ID4041, df_10_ID4041, df_11_ID4041, df_12_ID4041],
[df_01_ID4042, df_02_ID4042, df_03_ID4042, df_04_ID4042, df_05_ID4042, df_06_ID4042, df_07_ID4042, df_08_ID4042, df_09_ID4042, df_10_ID4042, df_11_ID4042, df_12_ID4042],
[df_01_ID4047, df_02_ID4047, df_03_ID4047, df_04_ID4047, df_05_ID4047, df_06_ID4047, df_07_ID4047, df_08_ID4047, df_09_ID4047, df_10_ID4047, df_11_ID4047, df_12_ID4047],
[df_01_ID4049, df_02_ID4049, df_03_ID4049, df_04_ID4049, df_05_ID4049, df_06_ID4049, df_07_ID4049, df_08_ID4049, df_09_ID4049, df_10_ID4049, df_11_ID4049, df_12_ID4049],
[df_01_ID4056, df_02_ID4056, df_03_ID4056, df_04_ID4056, df_05_ID4056, df_06_ID4056, df_07_ID4056, df_08_ID4056, df_09_ID4056, df_10_ID4056, df_11_ID4056, df_12_ID4056],
[df_01_ID4059, df_02_ID4059, df_03_ID4059, df_04_ID4059, df_05_ID4059, df_06_ID4059, df_07_ID4059, df_08_ID4059, df_09_ID4059, df_10_ID4059, df_11_ID4059, df_12_ID4059],
[df_01_ID4075, df_02_ID4075, df_03_ID4075, df_04_ID4075, df_05_ID4075, df_06_ID4075, df_07_ID4075, df_08_ID4075, df_09_ID4075, df_10_ID4075, df_11_ID4075, df_12_ID4075]], dtype="object")
for j in range(len(nombres_df)):
for i in range(len(nombres_df[i])):
print (nombres_df[i][j])
我需要對其進行迭代并使用每個資料幀內的值進行操作。問題是，當我像往常一樣嘗試迭代時，我不能這樣做，因為我收到了這個錯誤：
5 6 for j in range(len(nombres_df)): 7 for i in range(len(nombres_df[i])): <-------- 8 print (nombres_df[i][j], end = " ")IndexError：用作索引的陣列必須是整數（或布爾）型別
我知道問題就在這里，len(nombres_df[i])但我不知道如何解決。
非常感謝
uj5u.com熱心網友回復：
我認為問題在于您在代碼的第二行中迭代了錯誤的索引。i里面應該range(len(nombres_df[i]))是j
nombres_df[i][j]你也應該倒置其中的索引nombres_df[j][i]
這應該可以解決問題
for j in range(len(nombres_df)):
for i in range(len(nombres_df[j])):
print (nombres_df[j][i])
