C# equivalents used for pseudo types and concepts:

Pseudo	C#
List[T]	List<T>
Dictionary[K, V]	Dictionary<K, V>
Set[T]	Set<T>
Tuple[T1, T2..]	a custom class or Tuple<T1, T2..>
Array[T, count]	T[]
Int	int
Float	float
String	string
for-loops	foreach, for
classes	classes
methods	methods
functions	static methods of main class

niceties

• Converting tuples to classes

  Pseudo tries to infer meaningful names for tuples and their fields based on their usage in the program. If it succeeds, it converts them to classes with readonly properties, otherwise it uses Tuple<..> and .Item1..Item9

  in football.cs:

  return line[:away_index - 3], line[away_index:result_index - 1], (int(goals[0]), int(goals[1]))

  Pseudo detects a candidat-tuple with field types: String, String and another candidat-tuple

  return sum(result_points(team, *result) for result in results)

  The pseudo type of result is inferred to be List[Tuple[String, String], Tuple[Int, Int]], so probably result is OK for a name of its class. Also all fields or result are passed to result_points

  def result_points(team, host, away, goals):

  so we can use host, away and goals as field names and finally we build a class node which pseudo later translates as:

  public class Result
  {
  		private readonly string host;
  		public string Host { get { return host; } }
  
  		private readonly string away;
  		public String Away { get { return away; } }
  
  		private readonly Tuple<int, int> goals;
  		public Tuple<int, int> Goals { get { return goals; } }
  
  		public Result(string host, string away, Tuple<int, int> goals)
  		{
  			this.host = host;
  			this.away = away;
  			this.goals = goals;
  		}
  }

  That analysis is done in Pseudo on the input pseudo syntax tree, the python code given here can be compiled to equivalent pseudo ast using pseudo-python
