How to give output of a file as input to other file,How to give the text entered in LineEdit in pyqt4 to another file as an input string

Question

import sys
from PyQt4.QtCore import SIGNAL
from PyQt4.QtGui import QDialog, QApplication, QPushButton, QLineEdit, QFormLayout

class Form(QDialog):
    def __init__(self, parent=None):
        super(Form, self).__init__(parent)

        self.le = QLineEdit()
        self.le.setText("Host")

        self.pb = QPushButton()

        self.pb.setText("Connect") 

        layout = QFormLayout()
        layout.addWidget(self.le)
        layout.addWidget(self.pb)

        self.setLayout(layout)
        self.connect(self.pb, SIGNAL("clicked()"),self.button_click)
        self.setWindowTitle("Learning")

    def button_click(self):
        # shost is a QString object
        shost = self.le.text()
        #what should I write here to access the other python file and give shost as input string to that file


app = QApplication(sys.argv)
form = Form()
form.show()
app.exec_()

Now when I enter text in lineedit and click connect pushbutton it should give the text as input to other python file which is given below. I need to modify the button_click(self) function in the above code so that it gives text in lineedit as input to the below python file.

 # Requiredfile.py
Enteredstring = input('Enter string:')
print Enteredstring

considering your pyqt code is correct,

import sys
from PyQt4.QtCore import SIGNAL
from PyQt4.QtGui import QDialog, QApplication, QPushButton, QLineEdit, QFormLayout

class Form(QDialog):
  def __init__(self, parent=None):
    super(Form, self).__init__(parent)

    self.le = QLineEdit()
    self.le.setText("Host")

    self.pb = QPushButton()

    self.pb.setText("Connect") 

    layout = QFormLayout()
    layout.addWidget(self.le)
    layout.addWidget(self.pb)

    self.setLayout(layout)
    self.connect(self.pb, SIGNAL("clicked()"),self.button_click)
    self.setWindowTitle("Learning")

  def button_click(self):
    # shost is a QString object
    shost = self.le.text()
    import Requiredfile.py
    Requiredfile.func(shost)


app = QApplication(sys.argv)
form = Form()
form.show()
app.exec_()

you make a function named func in your requiredfile.py and import Requiredfile.py in your gui file and pass the shost var to the file.

here's your Requiredfile.py

def func(shost):
    Enteredstring = input('Enter string:')
    print Enteredstring
    print shost

so here you get the shost in your Requiredfile.py, do whatever you want to do with shost
