How python uses the slice function to name slices

Editor to share with you how python uses the slice function to name slices, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Use the slice function to name slices

Using a large number of hard-coded index values can quickly confuse maintainability and readability. One way to do this is to use constants for all index values, but we can do better:

# ID First Name Last Name line_record = "2 John Smith" ID = slice (0,8) FIRST_NAME = slice (9,21) LAST_NAME = slice (22,27) name = f "{line_ record [first _ NAME] .strip ()} {line_ record [last _ NAME] .strip ()}" # name = = "John Smith"

In this case, we can avoid mysterious indexes by naming them with the slice function and then using them. You can also learn more about slice objects through the .start, .stop, and .stop properties.
