我有一個腳本,它工作正常,直到我爲用戶交互添加了一個文件查詢框。它不斷重複這個問題,並且只有通過使輸入/輸出文件相同來強制使下列命令(shutil.copy2)崩潰纔會退出。爲什麼?這將導致循環使用tkinter時無限循環
else:
#print "Does not exist"
newMetaFile=FileNm+"_BaseMetadata.xml"
root = Tkinter.Tk()
file = tkFileDialog.askopenfile(parent=root,mode='rb',title='Choose a xml base file to match with: '+File)
if file != None:
metafile=os.path.abspath(file.name)
file.close()
print metafile
shutil.copy2(metafile,newMetaFile)
print "copied"
else:
shutil.copy2('L:\Data_Admin\QA\Metadata_python_toolset\Master_Metadata.xml', newMetaFile)
tree=et.parse(newMetaFile)
print "Processing: "+str(File)

謝謝。修正它通過添加一個break語句,但現在我得到其他問題-http://stackoverflow.com/questions/9090111/attributeerror-len-error-with-ntpath-py-an-tkinter-py我不明白因爲os.path.join到現在還沒有任何問題。 – GeorgeC 2012-02-01 04:43:42
