我想将在文本框中输入的值传递给python程序

Question

我写了这段代码

app = Tk()
app.title('Myapp')
app.geometry('260x100+50+50')

labelText =StringVar()
labelText.set('Insert the version you want to check')
label1 = Label(app, textvar=labelText, height=4)
label1.pack()

stringadacercare = StringVar(None)
lastringa = Entry(app, textvar=stringadacercare)
lastringa.place(x=30, y=40, width=200)


progressbar = ttk.Progressbar(orient=HORIZONTAL, length=260, mode='determinate')
progressbar.pack(side='bottom')
progressbar.start()

app.mainloop()

我想将文本框接受的输入而不是raw_input传递到该程序中，以便将其绑定到testV

 import csv
 import re
 import os
 testV = raw_input('Insert the version you want to find: ')
 fileobj = csv.reader(open('c:\\paths1.csv', 'rb'), delimiter=' ', quotechar='|')
 for row in fileobj:

for x in row:
    with open(x) as f:
        for line in f:

            if re.match(testV, line):
                print 'The version match: '+ line
            else:
                print 'wrong version'     
    filesize= os.path.getsize(x)
print 'The file size is :'+ str(filesize) +' bytes';

有人可以帮我吗？ 先感谢您！！！！！

您确定要使用第二个脚本作为单独的程序吗？ 如果需要，可以使用子流程模块将变量作为命令行参数传递。

设置GUI以使用按钮并回调如下所示的内容：

import subprocess
from Tkinter import *
import ttk

def btnCallback():
    #this is the path to your other script
    cmdpath = '/path/to/test.py'

    #extract the textbox variable
    var = stringadacercare.get()

    progressbar.start()

    #pass the variable to the command line
    proc = subprocess.popen([cmdpath,var])

    #block while the subprocess executes
    proc.wait()

    progressbar.stop()

app = Tk()
app.title('Myapp')
app.geometry('260x100+50+50')

labelText =StringVar()
labelText.set('Insert the version you want to check')
label1 = Label(app, textvar=labelText, height=4)
label1.pack()

stringadacercare = StringVar(None)
lastringa = Entry(app, textvar=stringadacercare)
lastringa.place(x=30, y=40, width=200)

progressbar = ttk.Progressbar(orient=HORIZONTAL, length=260, mode='determinate')
progressbar.pack(side='bottom')

#use a button to execute the subprocess
buttonOK = Button(app,text='GO',command=btnCallback)
buttonOK.pack(side='bottom')

app.mainloop() 

重组测试脚本以接受命令行参数。 您也可以将其导入gui应用程序并调用main函数，直接传递变量。

import csv
import re
import os

#need the sys module to get the command line args
import sys

def main(testV):
    fileobj = csv.reader(open('c:\\paths1.csv', 'rb'), delimiter=' ', quotechar='|')

    for row in fileobj:
        for x in row:
            with open(x) as f:
                for line in f:
                    if re.match(testV, line):
                        print 'The version match: '+ line
                    else:
                        print 'wrong version'
                        filesize= os.path.getsize(x)
                        print 'The file size is :'+ str(filesize) +' bytes'

if __name__=='__main__':
    #get the first command line argument and pass it to main
    testV = sys.argv[1]
    main(testV)

如果要将测试例程用作模块而不是命令行使用，则可以为测试模块添加import语句，然后从按钮回调中调用它。

...
import mytestmodule

def btnCallback():
    #extract the textbox variable
    var = stringadacercare.get()

    progressbar.start()

    #call the main function from the test module
    mytestmodule.main(var)

    progressbar.stop()

...
