Add Icon to Tab (QTabWidget)?

Question

I’m working with a QTabWidget with three Tabs.
One of the tab is about Information/Help. So I want to use a picture of a Question Mark (.png) instead of the Text "help".

Is this Possible? I’m working with Python/PyQt and I can only find solutions for C++

int QTabWidget::addTab(QWidget *page, const QIcon &icon, const QString &label)

Adds a tab with the given page, icon, and label to the tab widget, and returns the index of the tab in the tab bar. Ownership of page is passed on to the QTabWidget.

void QTabWidget::setTabIcon(int index, const QIcon &icon)

Sets the icon for the tab at position index.
