What is Python?

• An ,
  for
  general-purpose programming

interpreted
high-level programming language

• Each statement translated into subroutines
• Platform-independent
• Dynamic typing
• Easier debugging
• Automatic memory management
• Adding or changing functions at runtime
• No need to recompile again to test a small
  section
• Slower
• Checking for errors- dynamic

What is Python?

• An ,
  for
  general-purpose programming

interpreted
high-level programming language

• Strong abstraction
• Closer to the end-user
• May use elements of natural language
• May be simpler
• May automate areas like memory management
