i'm retrieving my data from a CSV file into a QtableWidget, i created some methods to modify, delete, insert column and rows even new items... in the QtableWidget, so before going to the next step i need to convert the current QtableWidgetItem into a dictionary.( Not the data from the file!) by pressing a button .

class MyWindow(QMainWindow):
def __init__(self, *args, parent=None):
 super(MyWindow, self).__init__(parent)
 self.fileName = ""
 self.result = 

##### Event for the button
 self.ui.commandLinkButton.clicked.connect(self.generateCsvData)

 def loadCsvOnOpen(self, fileName): #Load CSV file
 if fileName:
 f = open(fileName, 'r') 
 mystring = f.read()
 if mystring.count(",") > mystring.count('t'):
 if mystring.count(",") > mystring.count(';') :
 self.delimit = ","
 elif mystring.count(";") > mystring.count(',') :
 self.delimit = ";"
 else:
 self.delimit = "t"
 elif mystring.count(";") > mystring.count('t'):
 self.delimit = ';'
 else:
 self.delimit = "t"
 f.close()
 f = open(fileName, 'r') 
 self.ui.tableView.setRowCount(0)
 self.ui.tableView.setColumnCount(0)
 for rowdata in csv.reader(f, delimiter=self.delimit):
 row = self.ui.tableView.rowCount()
 self.ui.tableView.insertRow(row)
 if len(rowdata) == 0:
 self.ui.tableView.setColumnCount(len(rowdata) + 1)
 else:
 self.ui.tableView.setColumnCount(len(rowdata))
 for column, data in enumerate(rowdata):
 item = QTableWidgetItem(data)
 self.ui.tableView.setItem(row, column, item) 
 self.ui.tableView.selectRow(0)
 self.isChanged = False
 self.setCurrentFile(fileName)
 self.ui.tableView.resizeColumnsToContents()
 self.ui.tableView.resizeRowsToContents()
 self.msg(fileName + " loaded")

 def generateCsvData(self): 
 for row in range(self.ui.tableView.rowCount()):
 for column in range(self.ui.tableView.columnCount()):
 item = self.ui.tableView.item(row, column)
 if item is not None:
 self.result[row[0]] = (row[1:])
 print(self.result)
 else:
 return

Try it:

import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *

class Example(QDialog):
 def __init__(self):
 super().__init__()

 self.tableWidget = QTableWidget()

 self.result = 
 button = QPushButton("Create a dictionary from QtableWidgetItem")
 button.clicked.connect(self.generateCsvData) # <---

 self.layout = QVBoxLayout()
 self.layout.addWidget(self.tableWidget) 
 self.layout.addWidget(button)
 self.setLayout(self.layout) 

 self.tableWidget.setRowCount(4)
 self.tableWidget.setColumnCount(2)

 for i in range(4):
 for j in range(2):
 item = QTableWidgetItem("Item -".format(i, j))
 item.setTextAlignment(Qt.AlignHCenter)
 self.tableWidget.setItem(i, j, item)

 def generateCsvData(self): # <---
 for row in range(self.tableWidget.rowCount()):
 for column in range(self.tableWidget.columnCount()): 
 item = self.tableWidget.item(row, column).text() 

 k = ":0>3::0>3".format(row, column)
 v = "".format(item)
 self.result[k] = v

 print("n key value")
 [ print(k, v) for k, v in self.result.items()]
