Installation:

pip install pyrecursive

Usage:

from pyrecursive import pyrecursive

def double(obj):
    return x * 2

pyrecursive(42, double)
# result: 84

pyrecursive([1, 2, 3, [4, 5, [6], 7], 8, 9, 'x'], double)
# result: [2, 4, 6, [8, 10, [12], 14], 16, 18, 'xx']

pyrecursive({'hamster': [1, 2, 3, {'test': 42}]}, double)
# result: {'hamster': [2, 4, 6, {'test': 84}]}

# In order to transform dict keys in depth: set transform_dict_keys variable to True (default: False).
pyrecursive({'hamster': [1, 2, 3, {'test': 42}]}, double, transform_dict_keys=True)
# result: {'hamsterhamster': [2, 4, 6, {'testtest': 84}]}

# In order not to transform dict values in depth: set transform_dict_values variable to False (default: True).
pyrecursive({'hamster': [1, 2, 3, {'test': 42}]}, double, transform_dict_values=False)
# result: {'hamster': [2, 4, 6, {'test': 42}]}

# In order to define custom rules for each object type in depth: set custom_rules variable.
pyrecursive([1, 2, 3, 'banana'], double, custom_rules={int: lambda x: x * 5})
# result: [5, 10, 15, 'bananabanana'] (multiplied by 5 when int, multiplied by 2 otherwise)
