Human: Write me a Python function to replace none with a blank dict. Assistant: 
Here is a Python function to replace none with a blank dict

import collections

def replace_none_with_blank_dict(d):
    """
    Replace None with a blank dict.
    """
    if d is None:
        return {}
    else:
        return d

# Enter the dictionary
d = collections.OrderedDict()

# Add some items to the dictionary
d['a'] = 1
d['b'] = 2
d['c'] = 3

# Calling the function
print((replace_none_with_blank_dict(d)))

#Example Output
# OrderedDict([('a', 1), ('b', 2), ('c', 3)])

#Remember to inspect code for bugs.
