Now, it’s time to discuss some important functions and methods used for sequences of all the types.ġ. To declare an empty string, use str() or it can be defined using empty string inside quotes.Įxample of Empty String in Python name = "PythonGeeks" Python does not have any char type as in other languages (C, C++), therefore, a single character inside the quotes will be of type str only.ġ. In python, the string is a sequence of Unicode characters written inside a single or double-quote. Python sequences are of six types, namely: There are many types of sequences in Python. Each sequence data type comes with its unique capabilities. Sequences are containers with items stored in a deterministic ordering. Let us see what is a sequence in Python? Will also see operations that can be performed on these sequences. One such category of python data structures is Sequence. Repeat this process throughout the heat map.When it comes to ease of writing code, Python is the most preferred language due to its large community, extensive library support, and data structures. Just move the mouse over a hierarchy of boxes in the heat map (from outer to inner ones) to make sure the method names tell a story that makes sense. Good names can make a world of difference in helping other get up to speed with the code base. In areas of the code where there maybe many alternative sequences through the code or the sequence may not be clear (i.e in cases where there are a number of boxes in the heat map that are flat rather than hierarchical) you can use the Python call graph library to make sense of it.īefore the new devs arrive you may want to profile and use runsnakerun to review your architecture as well as review the names of you methods/functions. It's amazing how many architectural details you can pick up by reviewing the heat maps.Īn alternative to profiling is to insert 'assert 0' statements in different locations of the code and review the tracebacks generated. ![]() Profile the application and view the results in runsnakerun. Here are the steps I tend to follow to get up to speed with Python based projects that anyone new to a project could also use.įirst inspect the directory structure of the project. There have been many times when I have had to start working on a code base that may have inadequate or no documentation and at times I have had to take over a project when the original team was removed from the project and so I had to figure out what was in the code base on my own. Just manual create a few diagrams that highlight the architecture of the application, a deployment diagram if there are many components to your application, and maybe document a few sequences that are critical to understanding of the application. Unfortunately, auto-generated diagrams are not going to be well crafted and are going to be heavy weight. I'm not a huge fan of UML but I do feel that well crafted and light weight UML diagrams can be helpful.
