The problem with the Generator, how to fix the error?

Question

Python

Greetings to those who read this question.
Could you help me?
So, I wrote a generator with gui, but there is a problem,
It does not write the required number of codes in txt.
Here is the form:

*Above and below lineEdits, in the middle pushButton

If you enter some number, then this number should be generated and written to txt.
But no matter how, when you click on the generate button, only 1 code is generated and written.

Here is the code itself:

class PMain(QtWidgets.QMainWindow):
    def __init__(self):
        super(PMain, self).__init__()
        uic.loadUi("interface.ui", self)
        self.setWindowTitle("Генератор Дискорд Нитро")
        self.setWindowIcon(QtGui.QIcon("`pwd`/icon.ico"))

        if self.lineEdit_2.text() == "Введи количество желаемых кодов:":
            self.pushButton.clicked.connect(self.gen)
        else:
            self.pushButton.clicked.connect(self.how_much)

    def gen(self):
        f = open("code.txt", "a+")
        code = "https://discord.gift/" + ''.join(random.choices(string.ascii_letters + string.digits, k=16))
        f.write(f"{code}\n")
        f.close()
        self.lineEdit.setText(code)

    def how_much(self):
        n = int(self.lineEdit_2.text())
        value = 1
        while value <= n:
             code = "https://discord.gift/" + ('').join(random.choices(string.ascii_letters + string.digits, k=16))
             f = open('code.txt', "a+")
             f.write(f'{code}\n')
             f.close()
        value += 1

Help!

Answer 1

value += 1

is outside the loop, so the loop is infinite.

Answer 2

def how_much(self):
        n = int(self.lineEdit_2.text())
        value = 1
        f = open('code.txt', "a+")
        while value <= n:
             code = "https://discord.gift/" + ('').join(random.choices(string.ascii_letters + string.digits, k=16))

             f.write(f'{code}\n')
             value += 1
       f.close()
