たぶん、以下で出来ます。
|

|
|
22
|

```python
|
|

|
+
import csv
|
|

|

|
|
25
|
+
for file in files:#すべてのファイルに以下を繰り返し実行

|

df.columns=column
|
|
31
|
+
fname=os.path.basename(file)#パスを除いた拡張子付きのファイル名のみを抽出
|
|
32
|
+
with open("/content/drive/MyDrive/処理済み株価/"+fname, "w", encoding='utf_8_sig') as f:
|
|
33
|
+
writer_q = csv.writer(f, quoting=csv.QUOTE_NONNUMERIC)
|
|
34
|
+
writer_q.writerow(column)
|
|
35
|
+
writer = csv.writer(f)
|
|
36
|
+
writer.writerows(df.values.tolist())
|
|
37
|

```
