Fastest way to populate QTableView from Pandas data frame

Question

I\'m very new to PyQt and I am struggling to populate a QTableView control.

My code is the following:

def data_frame_to_ui(self, data_frame):
                


        

Answer 1

Simple and faster way to write a dataframe to QtableWidget

# Takes a df and writes it to a qtable provided. df headers become qtable headers
@staticmethod
def write_df_to_qtable(df,table):
    headers = list(df)
    table.setRowCount(df.shape[0])
    table.setColumnCount(df.shape[1])
    table.setHorizontalHeaderLabels(headers)        

    # getting data from df is computationally costly so convert it to array first
    df_array = df.values
    for row in range(df.shape[0]):
        for col in range(df.shape[1]):
            table.setItem(row, col, QtGui.QTableWidgetItem(str(df_array[row,col])))
