class DataStorage:
def __init__(self, data):
self.data = data
dataVault = DataStorage(data)
dataVault1 = dataVault
dataVault2 = dataVault
...
but why not use a static_data.py (put your data in there) file and do:
>>> from static_data.py import DATA
This way you only load it once and it will be accessible throughout your
program.
