Python to RPN converter

RE: Python to RPN converter
A new release of the converter today:
  • Fixed CLΣ access by providing Python function CLStat()
  • Allow access to statistical registers e.g. RCL(12)
  • Added statistical example to the help file.
Here is an example Python program which can be converted to RPN, which finds the sum of x^2 between numbers _from and _to using the built in feature of the HP statistics function Σ+ by accessing register 12.

Code:
def sumsigma(_from, _to):
  CLStat()  # CLΣ
  for i in range(_from, _to + 1):
    StatPlus(i, i) # Σ+
  x = RCL(12)  # recall summation register
  print("sum of x^2 from", _from, "to", _to, "is", x)

Use: On Free42 type

1 Enter 10 XEQ SUMSIGMA

and you'll get the answer 385.

Its just a fun exercise - easily accomplished on the HP Prime with the one liner e.g. Σ(X^2,X,1,10)
