#hython

A Python 3 interpreter implemented in Haskell.

The goal of this project is to become more familiar with Haskell. It is not to produce a replacement for CPython or PyPy. I would like to implement as much of the core language as I can. While I list features out below, they're more for me to remember what I have remaining in each part of the project.

• Significant indentation
• Integer literals
• Floating point literals
• Imaginary literals
• Single quoted string literals
• Double quoted string literals
• Triple quoted string literals
• String escape sequences
• Byte literals
• All operators, delimiters, and keywords
• Implicit line joining in collections
• Explicit line joining via \\

• Scalar literals
• Adjacent string literal concatenation
• Function calls
• Attribute access
• Tuples
• List literals
• List comprehensions
• Dictionary literals
• Subscript operators
