※ 引述《WindSwan (←虛擬愛情絕緣體)》之銘言：
: 嗯...
: 其實問題的重點在於，
: 該怎麼讓python執行有空格的路徑呢＠＠"?
: 感覺上跟標題沒什麼關係...
: 由於路徑有Program Files 等各種不同有空格的軟體存在著，
: 故有此一問，
: 感謝QQ"
我po個範例好了

1F：→ ibmibmibm:第一個參數可以用list，就沒有空格的問題了 08/26 21:18
2F：推 Pomin:新手請教一下... main() 這種寫法...是哪個大師有教， 08/26 22:19
3F：→ Pomin:還是約定成俗的經驗寫法？ 08/26 22:19
4F：推 john12:請問一下，你說的list是加在哪? 08/27 09:24
5F：→ john12:還有我看不懂你的呼叫程式，你沒用到subproccess但是卻可以 08/27 09:27
6F：→ john12:你是用system，還是不懂你的呼叫方式 08/27 09:28
7F：推 john12:空白路徑我已經解決了，我使用os.system就可以了 08/27 10:13
8F：推 victel:習慣吧，許多程式語言的主程式都叫main()，例如C 08/28 01:47
9F：推 bizkit:感覺不錯的寫法(筆記) 08/28 12:12
