 This library contains a pure-python implementation of the blurhash algorithm, closely following the original swift implementation by Dag Ågren. The module has no dependencies (the unit tests require PIL and numpy). It exports only two functions, "encode" and "decode". The usage is as follows:
 
 ```python
-def blurhash.decode(blurhash, width, height, punch = 1.0, linear = False)
+blurhash.decode(blurhash, width, height, punch = 1.0, linear = False)
