※ 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，

我po個範例好了

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