Python vs. Ruby
Python and Ruby are the dynamic and object oriented programming languages. They are quite similar to each other. They differ from each other on the base of their way of execution and the syntax as well. Python compiles code to a virtual machine language more efficiently than Ruby. Syntax of Python makes everything clear and regular to much possible extent while the syntax of Ruby is free that let you to put multiple statements on the same line and allow you to indent your code. Just one kind of anonymous function is supported by the Python called lambdas while Ruby contains the Blocks, Procs and lambdas. In Python the built-ins can’t be modified but in Ruby it can be done.

Key Differences

In Python the indention as syntax element is different from Ruby.
Blocks are missed in Python but present in Ruby.
There are no regular native expression in Python but are present in Ruby.
