Key Difference between Python vs Ruby

• Python support multiple inheritance, while Ruby support single inheritance.
• Python is mainly used for academic, AI, machine learning, and scientific programming, while Ruby is used for web development and functional programming.
• Python is not a fully object-oriented programming language. Whereas Ruby is a fully object-oriented programming language.
• In Python, once a variable is set, you can't unset it back, while in Ruby, it will be present in the symbol table as long as the variable is in scope.
• Python lambda functions are larger, while Ruby supports only a single-line lambda function.
• Python is very explicit and elegant to read, while Ruby can be very hard to debug at times.
• Python has methods, while Ruby has functions.
