   Discovered byGuido Van Rossum in early 1990  Easy to learn  Interpreted, Object Oriented, High level programming language  Free and Open Source Python Object oriented High Level Easy to Learn Interpret ed

   Interpreter readsevery line individually, if it finds error then it stops processing it and gives the error report.  Translates program one statement at a time.  No intermediate object code is generated, hence are memory efficient.  Programming language like Python, Ruby use interpreters.  It takes less amount of time to analyze the source code but the overall execution time is slower.  Compiler process the entire code in one go and gives the complete list of error.  Scans the entire program and translates it as a whole into m/c.  Generates intermediate object code, hence requires more memory.  Programming language like C, C++ use compilers.  It takes large amount of time to analyze the source code but the overall execution time is comparatively faster.

  Python support proceduralparadigm as well as object-oriented paradigm. Procedure oriented Object Oriented

  Eg: C, VB,FORTRAN, Pascal. Eg: C++, Java, C#.net etc  Procedural oriented program executes step by step.  Top down approach  program is divided into small parts called function.  POP does not have any access specifier.  Data can move freely from function to function in the system.  Object oriented uses class, objects.  Bottom up approach  In oop, program is divided into parts called objects.  access specifiers named Public, Private, Protected, etc.  Objects can move through member functions.

  A high-level languageis a programming language designed to simplify computer programming. High-level code contains easy-to-read syntax that is later converted into a low-level language. There is no need to worry about the low level details like memory allocation etc. Hardware Machine language Assembly language High-level language C++ PythonJava
