Is there a difference between QFileDialog strings in PyQt4 and PyQt5?
I'm very new to python, so please be patient. I have a block of code that opens a QFileDialog using Python 3 and PyQt5:
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QFileDialog
import sys
class MCVE(QWidget):
def __init__(self):
super().__init__()
self.initialize()
def initialize(self):
self.setWindowTitle('MCVE')
self.setGeometry(50, 50, 400, 200)
btn = QPushButton('Example', self)
btn.clicked.connect(self.clicked)
self.show()
def clicked(self):
filename = QFileDialog.getOpenFileName(
self, "Open Template", "c:\",
"Templates (*.xml);;All Files (*.*)")
print(filename)
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = MCVE()
sys.exit(app.exec_())
In Python 2 using PyQt4 the print(filename) statement, after pressing the cancel button, outputs as an empty string. When I run the same code in Python 3 using PyQt5 I get:
('', '')
NOTE: The quotes are Single Quotes
Can someone explain what is going on? I couldn't find anything under the documentation between PyQt4 and PyQt5. I know that strings changed between Python 2 and Python 3, but I'm not sure those changes would cause an issue like this. Thanks!

It's not clear how the AttributeError in your title is involved in any of the stuff you describe in the body. Are you getting an AttributeError or not?

@eyllanesc That was totally my bad, when I clicked on 'Ask a Question' it had a previous question I was going to ask before I figured out what was going on. So the title was set from that. I have updated this!!

The getOpenFileName function in PyQt4 returns a string that is the name of the selected file, and if none is selected then it returns an empty string.
filename = QFileDialog.getOpenFileName(self, "Open Template", "c:\", "Templates (*.xml);;All Files (*.*)")
However in PyQt5 this returns a tuple of 2 elements where the first one is a string that has the same behavior as in PyQt4, and the second element is the filter used.
filename, filters = QFileDialog.getOpenFileName(self, "Open Template", "c:\", "Templates (*.xml);;All Files (*.*)")
Note: The majority of documentation of PyQt5 is in Qt5, since in general the names of the methods, the entries and the result are similar.

In this case, what would be the most reliable way to eliminate the filter part so I get a string with only the path name and the file? Basically mimicing PyQt4's behavior when converting to PyQt5. Example C:SomeArbitraryDirectoryfile.xml
