Refresh Pivot Table Data in Excel

In the Pivot data table, data can be grouped based on Dates, Numbers, and Text values. In the case of dates, we can group dates by months or year, months by years, etc.

At any time, data for the PivotTables in your workbook can be refreshed using the Refresh button. You can also refresh data from a source table in the same or a different workbook.  By default, PivotTables are not refreshed automatically when data in the source table is changed, but you can set your workbook to refresh its PivotTable data automatically when you open it.

How to generate byte code file in python?

Whenever the Python script compiles, it automatically generates a compiled code called as byte code. The byte-code is not actually interpreted to machine code, unless there is some exotic implementation such as PyPy. The byte-code is loaded into the Python run-time and interpreted by a virtual machine, which is a piece of code that reads each instruction in the byte-code and executes whatever operation is indicated. Byte Code is automatically created in the same directory as .py file, when a module of python is imported for the first time, or when the source is more recent than the current compiled file.

Next time, when the program is run, python interpreter use this file to skip the compilation step. Running a script is not considered an import and no .pyc file will be created. For instance, let’s write a script file abc.py that imports another module xyz.py. Now run abc.py file, xyz.pyc will be created since xyz is imported, but no abc.pyc file will be created since abc.py isn’t being imported. But there exist an inbuilt py_compile and compileall modules and commands which facilitate the creation of .pyc file.

Encrypt Image using Python

Encryption

It is nothing but a simple process in which we convert our data or information into secret code to prevent it from unauthorized access and keep it private and secure.

First, we will select an image, and then we will convert that image into a byte array due to which the image data will be totally converted into numeric form, and then we can easily apply the XOR operation to it. Now, whenever we will apply the XOR function on each value of the byte array then the data will be changed due to which we will be unable to access it. But we should remember one thing here our encryption key plays a very important role without that key we can not decrypt our image. It acts as a password to decrypt it.
