#撰寫迴圈將urls中的每一個連結的文字內容個別存入一個文字檔
#文字檔檔名以連結的檔名為檔名, 附檔名則將html改成txt.
#例如urls[0]的檔名為1943689, 故存成的文字檔必須是1943689.txt
#以下示範程式可以顯示 1943689的文字內容, 但你要寫迴圈來批次
#讀取與寫入內容. 完成後請email給我程式檔及所擷取的文字檔.(可以用zip壓縮)
想請教怎麼把文字檔檔名儲存成每個網址後面的數字
迴圈的部分也不太懂到底該怎麼寫....
各位可以救救我嗎
-------------------------------
我這樣寫可以嗎
for name in urls:
print(name[-12:-5])
然後要怎麼將每個網址的文字內容都另存一個文字檔

1F：→ uranusjr:已經是補救機會還只能問人, 我看還是明年再來對你比較好 06/30 16:43
2F：→ ck574b027:google "python 另存一個文字檔" 很困難嗎？ 06/30 21:47
3F：推 yauhh:for name in urls: ... 那樣可以,只要你假定網址都那個規格 06/30 21:52
4F：推 goldflower:你迴圈用open應該就能直接建立新的文件 然後再寫進去 07/01 17:00
5F：→ goldflower:比如f = open('hello.txt','w') 會建立一個叫hello的檔 07/01 17:02
6F：→ goldflower:菇狗一下 "文件讀寫 python" 應該會有很多資料 07/01 17:03
