Python3.4—實戰專案-自動下載圖片驗證碼，並儲存到專門資料夾，使用圖片驗證碼庫識別，然後打印出來

1、環境部署
參考文章《使用Python識別圖片驗證碼》內容，製造好圖片驗證碼識別庫msweb1.dat
1.1、對圖片驗證碼隨時下載的URL地址：http://www.msweb.com:8080/checkNumber.action

1.2、程式碼檔案儲存資料夾：C:\Python34\yzm\msweb1\mswebyzm，以及圖片驗證碼被儲存到的資料夾：C:\Python34\

1.3、圖片驗證碼URL下載儲存的資料夾：C:\Python34\yzm\msweb1\mswebyzm

2、python指令碼的原始碼檔案

#必須使用gbk語言格式

    count = 0
    for filename in os.listdir('C:/Python34/yzm/msweb1/mswebyzm/'):#讀取檔案目錄
        #print (filename)#輸入每個檔案的名稱
        yzmlist.append(filename)
