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'
If your field variable is of type QString the below code works fine for me.
QString str = "a,b,c";
QStringList list1 = str.split(",");
Output = [ "a","b", "c" ]
Try doing type(field) in your python interpreter and show us the output.
OR type cast your variable to str like this a=str(field).split(".")
It seems like 'a' is not really a String, but some other object generated by the PyQt library (maybe an input field ?). If you can find a way to get a real String out of this field (a.value(), a.text(), or something like that), you should be able to use split.
