This module gives full control over creating zip filesWe create a new Zipfile with name ( "testguru99.zip, "w")Creating a new Zipfile class, requires to pass in permission because it's a file, so you need to write information into the file as newzipWe used variable "newzip" to refer to the zip file we createdUsing the write function on the "newzip" variable, we add the files "guru99.txt" and "guru99.txt.bak" to the archive When you execute the code you can see the file is created on the right side of the panel with name "guru99.zip" Note: Here we don't give any command to "close" the file like "newzip.close" because we use "With" scope lock, so when program falls outside of this scope the file will be cleaned up and is closed automatically. Step 5) When you -> right click on file (testguru99.zip) and -> select your O.S (Windows Explorer), it will show the archive files in the folder as shown below.

Lookup Transformation Create an index for the column in a lookup table which is used in lookup condition. Since the lookup table will be queried for looking up the matching data, adding an index would increase the performance. If possible, instead of using lookup transformation use join in the database. As database joins are faster, performance will be increased. Delete unnecessary columns from the lookup table and keep only the required columns. This will bring down the overhead of fetching the extra columns from the database. Filter Transformation Use filter transformation as early as possible inside the mapping. If the unwanted data can be discarded early in the mapping, it would increase the throughput.' Use source qualifier to filter the data. You can also use source qualifier SQL override to filter the records, instead of using filter transformation. Aggregator Transformation Filter the data before aggregating it. If you are using filter transformation in the mapping, then filter the data before using aggregator as it will reduce the unnecessary aggregation operation. Limit the no of ports used in the aggregator transformation. This will reduce the volume of data that aggregator transformation stores inside the cache. Source Qualifier Transformation Bring only the required columns from the source. Most of the times not all the columns of the source table are required, so bring only the required fields by deleting the unnecessary columns. Avoid using order by clause inside the source qualifier SQL override. The order by clause requires additional processing and performance can be increased by avoiding it. - [How to Call a Function in Python (Example)](https://www.guru99.com/functions-in-python.html): A Function in Python is a piece of code which runs when it is referenced.
