How Do I Change the Size and Position of the Main Window in Tkinter and Python 3

Python 3, Tkinter 8.6. GUI examples in Windows 10

When you create your first window in Tkinter, you can set it’s starting size and position on the screen by using the geometry method.

When using this method, note that it only provides the window with the size and position when it is initialized. This means that the user can then change the size of the window and move it once it has first been put on the screen.

Initial Window Size

Add the Current Date to a Sheet When Data Is Added So That The Date Does Not Change(Static) – Google Sheets

Google Sheets, Google Apps Script: onEdit

You’ve probably come across the problem where you need to know when a piece of data has been added to your spreadsheet. You probably have been equally frustrated that there is no out-of-the-box function that will do just this.

You’ve tried TODAY() and NOW(), but they change dynamically. What you really need here is something that does not change.

Let’s look at two workarounds that can help you out with this problem.

How to Get Something from Google Sheets and Display it in the Sidebar in Google Apps Script

Google Apps Script: SpreadsheetApp, getUI, HTMLservice, 

What if you want to get a value or a range from Google Sheets and show it in your sidebar using Google Apps Script?

First, you will need to get the value or range by using Googles server-side script. Then you will have to display it client-side in your HTML document.

Documentation on getting the server-side and client-side talking nicely to each other is a little vague. Hopefully, this very basic tutorial will help clear things up.

In this tutorial, I will also be using Jquery.

Let’s get started.

Google Apps Script – Iterating Through Ranges in Sheets the Right and Wrong Way

Google Apps Script: SpreadsheetApp, getRange, getLastRow, getDataRange

I was trying to rush out some Google Apps Script code to deal with a task on Google Sheets recently. Basically, I had to search through a heap of data and find certain values and do something too them.

My column was reaching across the page to something like Column BK and my rows were over 1000 deep. Running this code was taking forever!!!

My immediate instinct was:

What have I done wrong?

…and my instinct was right.

The Good and Bad Way to Search Through Code

So after looking at my code again, I discovered that for some reason I go it into my head that I should be searching each cell for the value I needed and then doing something with it.

Sounds logical right? It’s sorta what you are meant to do.

The problem is that I was calling the sever and asking for the range in each cell as I was looping through the entire document. This is super costly and inefficient in terms of time.

Google talks about this in their Google Apps Script Best Practice page under Batch Operations.

Also, if you do run a costly code like this, then you will get a little red light in your Script tool bar that represents your Execution Hints:

Google Apps Script Execution Hints

Clicking on Execution Hints and expanding the side bar with provide you with a far-too-deserving-polite dressing down about your slow and server costly code.

Method Range.getValue is heavily used

The Good

Copy and paste ranges in excel with OpenPyXl and Python 3

OpenPyXl is a Python open library that allows you to read and write Microsoft Excel files. Specifically, the ‘*.xlsx’ file extension. It helps you to create programs to create and modify files and automate your processes in excel.

Python Logo

NOTE: This post requires that you have some knowledge of Python and the OpenPyXl library. The library also needs to be installed for you to use. 

Quite often, I find that I have to work with ranges of data that I need to either copy and paste into a new file or files, or copy > modify > paste into files.

The OpenPyXl library allows you to look at every cell of a file and either copy it or modify it by using the openpyxl.worksheet.Worksheet.cell() method. This method allows you to access each cell by the row and column as a numerical value. 

Note! Unlike everything else in coding, rows and columns start with one(1) and not zero(0).

To select whole ranges of our data we need to iterate through it by both row and column and then store that data in a list to be pasted to the new file, spreadsheet or location that we desire.

The following example will take you through the process. For your own data you will need to modify the file, sheet and range locations. Everything else should be good to go.

You can find the whole code at the end of the post.

Why does your MS Excel look weird?

To be honest my screenshots of the ‘.xlsx files will be in Libreoffice. But this simple example will be able to load without issue in MS Excel.

The Example
