Introduction to the Python programming language

5.1. Python vs. Perl vs. Java vs. C++

• URL: http://www.flat222.org/mac/bench/
• JVM startup time included ;)
• the results are an average of 3 executions

• Hash:

  for i in range(6000):
      		x={}
  		for j in range(1000):
          		x[j]=i
  			x[j]

• IO:

  f=open('/tmp/scratch','wb')
  	for i in xrange(1000000):
  	    f.write(str(i))
  	f.close()

• List:

  for i in range(3000):
     		v=['a','b','c','d','e','f','g']
  		for j in range(1000):
  		        v.append(j)
  		        v[j]

• No:
  actually, no code here for Python - this just calls the program; Java and C++ have some code, Python and Perl do not
  
  
• Speed:

  for x in xrange(20000000):
  		pass

• Native:

  from pymaths import *
  
  	obj=Maths()
  
  	for i in xrange(1000000):
  		obj.add(i,0)
