Question

I am working with python plugins.I have my field variable = “t_0″.”survey” I wanted to store only survey into another variable.Which function to use to get survey from “t_0″.”survey”?

I tried a=field.split(".") when i try to print a ,it gives

<PyQt4.QtCore.QStringList object at 0x01247228>

Is there any delete function or to find position of “.” from the string..?

If i try lstrip() or ljust() ,it gives error saying

AttributeError: 'QString' object has no attribute 'lstrip'..

If a is a QString, then calling a.split produces a QStringList, just as calling split on a Python str produces a list:

>>> qstr = QString("t_0.survey")
>>> slist = qstr.split(".")
>>> slist
<PyQt4.QtCore.QStringList object at 0x00BBCD88>

You can either cast QStringList to a Python list:

>>> list(slist)
[PyQt4.QtCore.QString(u't_0'), PyQt4.QtCore.QString(u'survey')]

or just extract the second element:

>>> slist[1]
PyQt4.QtCore.QString(u'survey')

And perhaps get rid of the QString wrapping:

>>> unicode(slist[1])
u'survey'
