# Welcome to PocketPy
PocketPy is a lightweight(~5000 LOC) Python interpreter for game engines.
It is extremely easy to embed. Including a compiler, optimizer and bytecode virtual machine. All of them are available in a single header file `pocketpy.h`, without external dependencies.
## What it looks like
```python
def is_prime(x):
if x < 2:
return False
for i in range(2, x):
if x % i == 0:
return False
return True
primes = [i for i in range(2, 20) if is_prime(i)]
print(primes)
# [2, 3, 5, 7, 11, 13, 17, 19]
```
# basic
The following table shows the basic features of PocketPy with respect to [CPython](https://github.com/python/cpython).
The features marked with `YES` are supported, and the features marked with `NO` are not supported.

| Tuple | `(1, 2, 'a')` | YES |
| Dict | `{'a': 1, 'b': 2}` | YES |
| F-String | `f'value is {x}'` | YES |
| Unpacking | `a, b = 1, 2` | YES |
| Star Unpacking | `a, *b = [1, 2, 3]` | NO |
| Exception | `raise/try..catch` | YES |
