DSE-Pseudocode-Compiler

A function that converts DSE-style Pseudocode into Python.

Supported styles

All styles and capitalization found throughout various years of past papers.

Feature list

  • Variable assignment
  • Comparison operators
  • Logical operators
  • if/ else/ else if statements (with or without then)
  • for loops
  • while loops
  • repeat... until loops
  • Input
  • Output
  • Pseudo-accurate arrays

Arrays

To not break for loops that aim to iterate over lists, the trait of array indices starting from 1 is retained. The compiler searches for the highest index for each array referenced, and initializes the list:

X = [None] * (highest_index + 1)

The compromise is X[0] will always return None.

Unsupported features

Type conversion of inputs will not be supported. You have to manually convert it:

Input A, B
Output A * B

to

Input A, B
Output int(A) * int(B)

Plain language used in pseudocode will not be supported. Convert them to Python manually:

X <-- 2
Y <-- 4
Output the square root of X
Output the integral part of X / Y

to

from math import sqrt
X <-- 2
Y <-- 4
Output sqrt(X)
Output X // Y
