  In recent years, data has emerged as the new gold, serving as a powerful tool
for creating intelligent systems. However, procuring high-quality data remains
challenging, especially for code. To address this, we developed TinyPy
Generator, a tool that generates random Python programs using a context-free
grammar. The generated programs are guaranteed to be correct by construction.
Our system uses custom production rules (in the Backus-Naur Form (BNF) format)
to recursively generate code. This allows us to generate code with different
levels of complexity, ranging from code containing only assignments to more
complex code containing conditionals and loops. Our proposed tool enables
effortless large-scale Python code generation, beneficial for a wide range of
applications. TinyPy Generator is particularly useful in the field of machine
learning, where it can generate substantial amounts of Python code for training
Python language models. Additionally, researchers who are studying programming
languages can utilize this tool to create datasets for their experiments, which
can help validate the robustness of code interpreters or compilers. Unlike
existing research, we have open-sourced our implementation. This allows
customization according to user needs and extends potential usage to other
languages.
