我使用Python 2.7和Tkinter在Windows中運行控制檯應用程序。我正在使用文件瀏覽器來選擇文件。我的問題是,在用戶選擇文件和使用路徑的腳本之間,Windows試圖打開它。在這種情況下,它是一個.pages文件,它試圖用Word打開它。我不希望發生這種情況。我怎樣才能阻止它>如何禁止使用python處理Windows文件?
只爲背景,這裏的代碼:
from Tkinter import *
from tkFileDialog import *
import os.path
import shutil
import sys
import tempfile
from zipfile import ZipFile
import subprocess
class uiclass():
def __init__(self,root):
b = Button(root, text="Browse", command=self.callback)
w = Label(root, text="Please choose a .pages file to convert.")
w.pack()
b.pack()
def callback(self):
print "click!"
global y
y = askopenfilename(parent=root, defaultextension=".pages")
self.view_file(y)
def view_file(self,filepath):
subprocess.Popen(filepath, shell=True).wait()
PREVIEW_PATH = 'QuickLook/Preview.pdf' # archive member path
#pages_file = raw_input('Enter the path to the .pages file in question: ')
pages_file = y
pages_file = os.path.abspath(pages_file)
filename, file_extension = os.path.splitext(pages_file)
if file_extension == ".pages":
tempdir = tempfile.gettempdir()
temp_filename = os.path.join(tempdir, PREVIEW_PATH)
with ZipFile(pages_file, 'r') as zipfile:
zipfile.extract(PREVIEW_PATH, tempdir)
if not os.path.isfile(temp_filename): # extract failure?
sys.exit('unable to extract {} from {}'.format(PREVIEW_PATH, pages_file))
final_PDF = filename + '.pdf'
shutil.copy2(temp_filename, final_PDF) # copy and rename extracted file
# delete the temporary subdirectory created (along with pdf file in it)
shutil.rmtree(os.path.join(tempdir, os.path.split(PREVIEW_PATH)[0]))
print('Check out the PDF! It\'s located at "{}".'.format(final_PDF))
self.view_file(final_PDF) # see Bonus below
sys.exit()
else:
sys.exit('Sorry, that isn\'t a .pages file.')
if __name__ == '__main__':
root = Tk()
uiclass(root)
root.wm_title("Pages to PDF")
root.mainloop()
是否有可能將問題隔離,以較少代碼段?對於我來說,理解它有點困難因爲全局變量有點奇怪,並且有很多導入的名字。 – icedtrees
不要調用'subprocess.Popen(filepath,shell = True).wait()'if'file_extension ==「.pages」' – jfs
@icedtrees我認爲問題出現在else之前的最後幾行:',其中打開文件的實際代碼是。我不確定... – evamvid
