Question: .append Deprecated how to store values using .concat

PySimpleGUI == 4.59.0
Python == 3.9
Pandas == 1.42.
I'm currently building a questionnaire for a non profit organization and having issues updating the .append method to a .concat. I've attempted to turn off future warnings. My goal is to store the values in an Excel spreadsheet. Open for any solution to store the values to a spreadsheet
It looks like this issue is not about PySimpleGUI.
Example Code
from pathlib import Path
import pandas as pd
import PySimpleGUI as sg
EXCEL_FILE = r'd:\Example.xls'
items = ['Date', 'Item', 'Price']
df1 = pd.read_excel(EXCEL_FILE, index_col=0) if Path(EXCEL_FILE).is_file() else pd.DataFrame()
layout = [
[sg.Text(item), sg.Push(), sg.Input('', do_not_clear=False, key=item)]
for item in items] + [
[sg.Button('Submit'), sg.Button('Exit')],
]
window = sg.Window('Accounting Book', layout)
while True:
event, values = window.read()
if event in (sg.WIN_CLOSED, 'Exit'):
break
elif event == 'Submit':
if '' not in values.values():
try:
values['Price'] = float(values['Price'])
except ValueError:
continue
df2 = pd.DataFrame([values])
df1 = pd.concat([df1, df2], ignore_index=True)
df1.to_excel(EXCEL_FILE, index=True)
window.close()
Yea... a head-scratcher.
There is one demo program that imports pandas
https://github.com/PySimpleGUI/PySimpleGUI/blob/master/DemoPrograms/Demo_Table_Pandas.py
Here's the code... it doesn't have append
anywhere in it
#!/usr/bin/env python
import PySimpleGUI as sg
import pandas as pd
# Yet another example of showing CSV data in Table
def table_example():
sg.set_options(auto_size_buttons=True)
filename = sg.popup_get_file(
'filename to open', no_window=True, file_types=(("CSV Files", "*.csv"),))
# --- populate table with file contents --- #
if filename == '':
return
data = []
header_list = []
button = sg.popup_yes_no('Does this file have column names already?')
if filename is not None:
try:
# Header=None means you directly pass the columns names to the dataframe
df = pd.read_csv(filename, sep=',', engine='python', header=None)
data = df.values.tolist() # read everything else into a list of rows
if button == 'Yes': # Press if you named your columns in the csv
# Uses the first row (which should be column names) as columns names
header_list = df.iloc[0].tolist()
# Drops the first row in the table (otherwise the header names and the first row will be the same)
data = df[1:].values.tolist()
elif button == 'No': # Press if you didn't name the columns in the csv
# Creates columns names for each column ('column0', 'column1', etc)
header_list = ['column' + str(x) for x in range(len(data[0]))]
except:
sg.popup_error('Error reading file')
return
layout = [
[sg.Table(values=data,
headings=header_list,
display_row_numbers=True,
auto_size_columns=False,
num_rows=min(25, len(data)))]
]
window = sg.Window('Table', layout, grab_anywhere=False)
event, values = window.read()
window.close()
table_example()
I'm struggling to find any connection to PySimpleGUI.
