Use Qt.FramelessWindowHint

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtCore import Qt

if __name__ == "__main__":
    app = QtWidgets.QApplication([])
    widget = QtWidgets.QWidget()
    widget.setWindowFlags(widget.windowFlags() | Qt.FramelessWindowHint)
    widget.show()
    app.exec()
