[GIS] How to use raw_input() in QGIS python console

pythonqgis

I'm hoping to use raw_input() inside a loop to prompt the user when s/he wants to continue running the script. However, I'm getting an error:

Traceback (most recent call last):
   File "<input>", line 1, in <module>
EOFError: EOF when reading a line

Is this function supported in qgis' python console? If not, do you have any suggestion?

I don't need to read the user's input. I just need the loop to pause for a while to let the user do some other stuff, then when ready, to resume working again.

The alternative to raw_input is QInputDialog.getText as explained in Maximus' answer above. A quick and Dirty example would be:

##Import libraries
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from qgis.core import *
from qgis.gui import *
from qgis.utils import *

from PyQt4.QtGui import QInputDialog #this is for your dialogs

 tempTuple = QInputDialog.getText(None, "Your Name" ,"Enter your Full Name: ")
 userName = tempTuple[0]

[GIS] How to clear python console in QGIS

Ok, so I have been playing around with QGIS console.py to see if you can do this yourself and it turns out to be pretty easier.

Open up console.py which, if you have installed using OSGeo4W, is in C:\OSGeo4W\apps\qgis\python\qgis. Then look for the python method called def entered(self): and replace it with the following:

def entered(self):
    self.cursor.movePosition(QTextCursor.End, QTextCursor.MoveAnchor)
    self.setTextCursor(self.cursor)
    command = unicode(self.currentCommand())
    if command == 'clear':
        self.clearConsole()
    else:
        self.runCommand(command)

also add the following method after the entered method:

def clearConsole(self):
      self.clear()
      self.insertTaggedText("To access Quantum GIS environment from this console\n"
                          "use qgis.utils.iface object (instance of QgisInterface class).\n"
              "\n", ConsoleHighlighter.INIT)
      self.displayPrompt(False)

Save console.py and close, and restart QGIS.

The clearConsole will clear out the console window and return it the way it was when you first open it when the clear command is entered into the window.

However this doesn't clear the history, or restart any variables but I wouldn't want it to if I was using it.

Hope this helps with what you need.

EDIT: As of V1.7 this is a built in feature of the Python console. Just call qgis.console.clearConsole() in the Python console to clear it.

QGIS – How to Fix SIP Module Loading Error (Python)

In a command window, type set > set.txt to get a list of all environment variables you have set. Your python installation may have set some values that QGIS does not like.

The PATH variable is save, because qgis.bat sets its own path variable, but PYTHONPATH or something else may be harmful.

Once you found a link to C:\Python27, go to the system properties and change the environment variable (not sure how the commands are in your language version).
