I made a very basic and working 1-pass cross-assembler in Pythonista. It was more of a proof of concept, to help me understand the book I’m reading (Assemblers and Loaders) 👨‍💻

A code editor displays Python code on the left for an assembler, with an output console on the right showing hexadecimal values.

PS Notice it’s still big-endian, while it should be little-endian. 😬
