The term Programming paradigm means the methodology for writing program codes. In general, two paradigms govern how you can construct a program. These two ways are: a process-oriented model an object-oriented model Many programming languages support both the paradigms like python. Python allows the users to code using both process-oriented and object-oriented methodologies. However, Java …
