Funz plugin: Python 3

This plugin is dedicated to launch Python 3 calculations from Funz. It supports the following syntax and features:

• Input

  • file type supported: '*.py', any other format for resources
  • parameter syntax:
    • variable syntax: ?[...]
    • formula syntax: ${...}
    • comment char: #
  • example input file:

  import math as m
  def branin(x1,x2):
      x1 = x1*15-5
      x2 = x2*15
  
      return (x2 - 5/(4*m.pi^2)*(x1^2) + 5/m.pi*x1 -6 )^2 + 10*(1-1/(8*m.pi))*m.cos(x1) +10
  print( "z={0}".format( branin( ?[x1~[1,2]], ${?[x2] +1.23} | #.###)))
  

  • will identify input:
    • x1, expected to vary inside [1,2]
    • x2, expected to vary inside [0,1] (by default)
  • replace ${?[x2] + 1.23 | #.###} expression by its evaluation

• Output

  • file type supported: 'out.txt'
  • read any named value printed with =, like print("z={0}".format(1.234))
  • example output file:

  import math as m
  def branin(x1,x2):
      x1 = x1*15-5
      x2 = x2*15
  
      return (x2 - 5/(4*m.pi**2)*(x1**2) + 5/m.pi*x1 -6 )**2 + 10*(1-1/(8*m.pi))*m.cos(x1) +10
  
  print( "z={0}".format( branin( 0.5, 0.132) ) )
  

  • will return output:
    • z=3.000715
