Taking advantage of the for loop and range function in python, we can draw a variety of for pyramid structures. The key to the approach is designing the appropriate for loop which will leave both vertical and horizontal space for the position of the symbol we choose for drawing the pyramid ...
Did we define an interface for our duck? No! Did we program to the interface instead of the implementation? Yes! And, I find this so nice. As Alex Martelli points out in his well known presentation about Pythonsoftware designpatterns,“Teaching the ducks to type takes a while, but saves...
The Python style guide, also known as Python Enhancement Proposal no 8 (PEP 8), provides recommendations for readability and consistency in your code, making it easier for developers to collaborate and maintain projects over time. You can find the style guide details on its official page here:h...
Features of Python LanguageIn this section, we will learn about the different features of Python language.InterpretedPython is processed at runtime using the interpreter. There is no need to compile program before execution. It is similar to PERL and PHP.Object-Oriented...
"programtoaninterface,nottoan implementation" that'smostly done with "duck typing" in Python -- rarely w/"formal" interfaces actually similar to "signature-based polymorphism" in C++ templates 11 Duck Typing Helps a Lot! 12 Teaching the ducks to type takes a while, but saves you a lo...
Automatic Program Repair (APR) can automatically detect and fix bugs, thus helping developers to improve the quality of software products. As a critical component of APR, software bug fix patterns have been revealed by existing studies to be very effective in detecting and fixing bugs in ...
I sometimes hear this called “temporal coupling” — two separate pieces of code that must be called in the right order for the program to work correctly. All stateful software has some degree of this, but as with other kinds of coupling, reducing temporal coupling makes the codebase ...

In this tutorial blog, we will be guiding you to Draw Circle patterns using Python. We have added the Video Tutorial, the source code and the output of the program. So let us begin with How to Draw Circle patterns using Python.
We'll get to handling exceptions in a minute, but first, let's discover what we should do if we're writing a program that needs to inform the user or a calling function that the inputs are somehow invalid. Wouldn't it be great if we could use the same mechanism that Python uses?
