Features of Python1. Easy to use – Due to simple syntax rule2. Interpreted language – Code execution &interpretation line by line3. Cross-platform language – It can run onwindows,linux,macinetosh etc. equally4. Expressive language – Less code to be written as ititself express the purpose of the code.5. Completeness – Support wide rage of library6. Free & Open Source – Can be downloaded freelyand source code can be modify for improvementVisit : python.mykvs.in for regular updates
Shortcomings of Python1. Lesser libraries – as compared to otherprogramming languages like c ,java,.net2. Slow language – as it is interpreted languages,itexecutes the program slowly.3. Weak on Type-binding – It not pin point on use of asingle variable for different data type.Visit : python.mykvs.in for regular updates
