Невыполнение функции в PyQt5

Функция в PyQt5, не выполняется от слова совсем, ошибки в терминале нет, реакции = 0, нужно прогнать значение string через функцию которая обменяет каждый символ на иной, используя свою библиотеку, через функцию проходит, и текст назначается переменной, но почему-то не выводится, ломаю голову второй день, мой первый проект, для себя.

Вот нормальный вариант перевода:

_di = {"Q": "Z9:X1:", "W": "Z8:X2:", "E": "Z7:X3:", "R": "Z6:X4:", "T": "Z5:X5:", "Y": "Z4:X6:", "U": "Z3:X7:", "I": "Z2:X8:", "O": "Z1:X9:", "P": "Z0:X0", "A": "A9:S1:", "S": "A8:S2:", "D": "A7:S3:", "F": "A6:S4:", "G": "A5:S5:", "H": "A4:S6:",
       "J": "A3:S7:", "K": "A2:S8:", "L": "A1:S9:", "Z": "A0:S0:", "X": "Q9:W1:", "C": "Q8:W2:", "V": "Q7:W3:", "B": "Q6:W4:", "N": "Q5:W5:", "M": "Q4:W6:", "!": "Q3:W7:", "#": "Q2:W8:", "$": "Q1:W9:", "%": "Q0:W0:", "?": "O9:I1:", "*": "O8:I2:"}
trans = str.maketrans(_di)

def coding(self):
    text = self.plainTextEdit.toPlainText()
    text = text.translate(trans)
    self.plainTextEdit_2.setPlainText(text)

спасибо, я абсолютный новичёк, так что делал на базовых знаниях , так что ужас это нормально))
огромное спасибо за подсказку, все предложенное изучу и запомню, благодарю вас.
