<｜begin▁of▁sentence｜>### Instruction:
Given a sequence of values, how can you continuously update the running mean and standard deviation as each new value is added, particularly if some values are added multiple times?
### Response:
from RunningMean import RunningMean

# Initialize a RunningMean object
running_mean = RunningMean()

# Add a single value to the RunningMean
unning_mean.add(value=5)

# Add the same value multiple times to the RunningMean
running_mean.add(value=3, repeat=4)

# Print the current mean and standard deviation
print('Mean:', running_mean.mean())
print('Standard Deviation:', running_mean.std())
