- 26. Simple Python isvery simple As compared to other popular languages like Java and C++, it is easier to code in Python. Python code is comparatively 3 to 5 times smaller than C/C++/Java code
- 27. Print Hello Bhopal! INC #include <stdio.h> int main(){ printf("Hello Bhopal!"); return 0; } IN JAVA public class HelloWorld{ public static void main( String[] args ) { System.out.println( "Hello Bhopal!" ); } } IN PYTHON print('Hello Bhopal!')

- 31. Dynamically Typed IN Python a=10 a=“Bhopal” INC int a; a=10; a=“Bhopal”;
- 32. Robust Python hasvery strict rules which every program must compulsorily follow and if these rules are violated then Python terminates the code by generating “Exception” To understand python’s robustness , guess the output of the following /C++ code: int arr[5]; int i; for(i=0;i<=9;i++) { arr[i]=i+1; }
- 33. Robust In Pythonif we write the same code then it will generate Exception terminating the code Due to this other running programs on the computer do not get affected and the system remains safe and secure
- 34. Supports Multiple Programming Paradigms Python supports both procedure-oriented and object- oriented programming which is one of the key python features. In procedure-oriented languages, the program is built around procedures or functions which are nothing but reusable pieces of programs. In object-oriented languages, the program is built around objects which combine data and functionality
- 35. Compiled As Well AsInterpreted Python uses both a compiler as well as interpreter for converting our source and running it However , the compilation part is hidden from the programmer ,so mostly people say it is an interpreted language
- 36. Cross Platform Let’sassume we’ve written a Python code for our Windows machine. Now, if we want to run it on a Mac, we don’t need to make changes to it for the same. In other words, we can take one code and run it on any machine, there is no need to write different code for different machines. This makes Python a cross platform language
- 37. Extensible Python allowsus to call C/C++/Java code from a Python code and thus we say it is an extensible language We generally use this feature when we need a critical piece of code to run very fast . So we can code that part of our program in C or C++ and then use it from our Python program.
- 38. Huge Library ThePython Standard Library is huge indeed. It can help you do various things like Database Programming , E-mailing ,GUI Programming etc
