python-autocast-decorator

Decorator for automatically casting string inputs to their most likely Python data types.

This implementation runs ast.literal_eval() on all inputs. This is simple and reliable, but fairly slow, and therefore probably inappropriate for code that must run fast.

This decorator uses wrapt to enable signature-preserving decoration.

from autocast import autocast

@autocast
def my_function(arg):
    print(type(arg))

>>> my_function('3')
<type 'int'>
