Comparison of Python with C and Java

A Simple Comparison between “C” and “Python”

 Example : Write a source code in C to print 1 to 10 numbers.

“C “Code:

#include<stdio.h> int main( ) { int i = 1; for (i = 1; i <= 10; i++) { printf(“%d\n”, i); } return (0); }

Output

0 1 2 3 4 5 6 7 8 9 10

The below is the Python code for the same example

>>> for i in range(11): print(i)

Output

0 1 2 3 4 5 6 7 8 9 10

Comparison with Java

1.Intuitive Data Structures

Lists, tuples,Sets, Dictionaries

Powerful, yet simple and intuitive to use

Flexible (mixed data types)

2.English-like commands

Java: String name=”Bob”;

System.out.println(name);

Python: name=’Bob’

print(name)

3.One-Liners

Elegant 1-line solutions to what takes a whole block of code in other languages.

One example: swap x and y

Java:  int temp=x;

x=y;

y = temp;

Python: x,y=y,x

4.Simple syntax

             Some programming languages will kill you with parenthesis, brackets, braces, commas and colons. With Python you spend less time debugging syntax and more time programming.

5.Dynamically typed

No type when declaring a variable

Skip headaches of java type casting

Java: int x=1;

x=(int)x/2;       x now equals 0

x can never equal 0.5

Python:

x=1

x=x/2           x now equals 0.5

We summarized the differences in the below table

Java	Python
Java programs are slower	Python programs run faster
Java uses traditional braces to start and end.	Python uses indentation to start and end blocks.
Java employs static typing	Python uses dynamic typing
Java is a strongly typed language	Python is not a strongly typed language
Java does not compile to native byte code.	Python compile to native byte code
Java is complex	Python is simpler and more compact
Java does not allow the data type of variable to be changed	Python allows the data type of variable to be changed.
Java code is lengthier	Python code is shorter.
Java applications can work across various platforms.	Python applications do not support various platforms.
Java code is difficult to understand.	Python code is easy to understand
Similarities: Both are programming languages.
