The result is not written to notepad?

Question

Python

I have a Qt5 application and there is a "save" button, here is the function code for it:

def save_result():
    open('result.txt', 'w').write("save test")
    open('result.txt', 'w').close()
    print('test')

ui.pushButton_2.clicked.connect(save_result)  # Сохранить результат

The thing is, when I click on this button, test is displayed in the console, as intended, but nothing is entered in the notepad.

Answer 1

file = open('result.txt', 'w')
file.write("save test")
file.close()

or

with open('result.txt','w') as file:
  file.writelines('save test')
