Question

我正在创建一个GUI，其中我从用户那里获得输入（文件名）。

然后我必须在该文件上运行一些shell脚本并分别显示每个脚本的输出。

我有点坚持使用子进程模块。每次我跑，都会引发错误。

另一件事是，我如何创建一个全局字符串变量，因为我无法访问我在另一个函数中使用的变量。

CODE：

import sys
from Tkinter import *
from tkFileDialog import *
import subprocess
import os

FileName = ""
FilePath = ""


def browse():

    Tk().withdraw() 
    FilePath = askopenfilename(filetypes = (("ApkFiles","*.apk"),("All files", "*")))
    print FilePath
    Parts = FilePath.split("/")
    FileName = Parts[-1]
    name = str(FileName)
    #print FileName


def process():

    print FileName
    #subprocess.call("cat ", FileName, shell=True)
    #Content = open(self.filename,"r").readlines()
    #print Content
    #subprocess.call("command-name-here")
    #output = subprocess.call(["/path/to/command", "arg1", "-arg2"])
    #subprocess.Popen("ls", stdout=subprocess.PIPE, shell=True)
    #subprocess.call ("ls")

    subprocess.call (['cp filename /Home/dinesh/Base/ApkFiles/'])
    subprocess.call (['cd /Home/dinesh/Base'])l
    subprocess.call (['./AppSplit 0.1 0.1 0.8'])
    Status = subprocess.call (["AppSplit.sh" ,"filename"])
    #exit (Status)
    #   exit (0)



gui = Tk()  #create an object
gui.title("Select an app to be clustered")
gui.geometry("700x400")

GuiLabel1 = Label(gui,text="Select an app to be clustered").grid(row=0 , column=4)
GuiLabel2 = Label(gui,text="ApkFile").grid(row=3 ,column=3)

bar=Entry(gui).grid(row=3, column=4)


button1= Button(gui, text="Browse", command = browse).grid(row=3, column=5)
button2= Button(gui, text="Cluster", command = process).grid(row=4, column=5)

gui.mainloop()  #necessary for windows

对于subProcess.call，您需要将参数作为每个字符串的字符串列表传递，而不是作为列表中的单个字符串。

subprocess.call (['cp', filename, '/Home/dinesh/Base/ApkFiles/'])
# or use Python
shutil.copy(filename, '/Home/dinesh/Base/ApkFiles/')

subprocess.call (['cd', '/Home/dinesh/Base'])
# or use python
os.chdir('/Home/dinesh/Base')

subprocess.call (['./AppSplit', '0.1 0.1 0.8'])

您可以将全局变量放在函数定义之外，并在函数

中使用它们全局关键字

globalvar1 = "This is global"

# in the function
def myfunc():
    global globalvar1

使用python创建GUI（对文件进行操作）
