ProbDistribution¶

class
ProbDistribution
(data, shots=None)[source]¶ Bases:
dict
A generic dictlike class for probability distributions.
Builds a probability distribution object.
 Parameters
data (dict) –
Input probability data. Where the keys represent a measured classical value and the value is a float for the probability of that result. The keys can be one of several formats:
A hexadecimal string of the form
"0x4a"
A bit string e.g.
'0b1011'
or"01011"
An integer
shots (int) – Number of shots the distribution was derived from.
 Raises
TypeError – If the input keys are not a string or int
ValueError – If the string format of the keys is incorrect
Methods
Build a probabilities dictionary with binary string keys
Create a new dictionary with keys from iterable and values set to value.
Return the value for key if key is in the dictionary, else default.
Build a probabilities dictionary with hexadecimal string keys
If key is not found, d is returned if given, otherwise KeyError is raised
Remove and return a (key, value) pair as a 2tuple.
Insert key with a value of default if key is not in the dictionary.
If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
