<｜begin▁of▁sentence｜>### Instruction:
As a chemical technician, you are often required to maintain and record data related to experimental processes. For instance, you may need to constantly update the running average of a chemical solution's properties over time. Can you find out the number of data points that have been included in the calculation of the current average value?
### Response:
from RunningMean import RunningMean

# Create a running mean object
current_running_mean = RunningMean()

# Add some values to the running mean
current_running_mean.push(10)
current_running_mean.push(20)
current_running_mean.push(30)

# Get the length of the running mean (number of elements)
length = len(current_running_mean)

print('Number of elements in the running mean:', length)
