[英]How to suppress Windows file handling with python?
我正在Windows中使用Python 2.7和Tkinter运行控制台应用程序。 我正在使用文件浏览器来选择文件。 我的问题是,在用户选择文件和使用路径的脚本之间,Windows也会尝试打开它。 在这种情况下,它是一个.pages文件,并尝试使用Word打开它。 我不希望这种情况发生。 我该如何停止>
仅出于上下文考虑,下面是代码:
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()
正如JFSebastian指出的那样,我的问题是,每次循环再次运行时,它都会重新打开PDF(因为file_extension
变量仍设置为.pages
。在此之后,我对解决问题的代码进行了一些更改。
谢谢JF!
