This means the expression 'a'*20 is replaced by 'aaaaaaaaaaaaaaaaaaaa' during compilation to save a few clock cycles during runtime. Constant folding only occurs for strings having a length of less than 21. (Why? Imagine the size of .pyc file generated as a result of the expression '...
Clustering– a technique that groups data points based on their similarities. Each group is called a Cluster. K-Means Clustering– an unsupervised learning technique that looks for a fixed number (k) of means (centroids) of data points, and assigns them to the nearest cluster. ...
Python is known for being powerful, fast and for making programming more fun. Python coders can dynamically type variables without having to explain what the variable is supposed to be. Users can download Python at no cost and start learning to code with it right away. Thesource codeis freely...

While using the ArcGIS API for Python, we primarily work with well-known IDs called as wkid. For instance, the wkid of Web Mercator PCS explained above is 3857. Occasionally, you might see a latestWkid being used. The latestWkid represents the current wkid value associated with the same ...
periods are often used in computing for readability and clarity. by separating words and elements, it becomes easier for humans and computers to comprehend what each word/element means in relation to the larger context. for example, by putting a period at the end of a phrase within an html ...
