I have a list of data e.g. A = [1,2,3,10,4,3.5,16,11,19,6,13]
Now I want to find the mean value of this data set when entry value is less than 10.
How can I do it in Python?

2`sum(A1)/len(A1)`. Or, if you want the first `n` numbers from `A`: `sum(A[:n])/n`. – 9769953 Jan 30 '20 at 08:34

You can use statistics.mean
from statistics import mean
a = [1,2,3,4,5,6,7,8,9,10]
print(mean(a)) # 5.5

You can get sub list using list slicing - A[start:stop:step]
python3.*:
>>> sum(A[:10]) / 10 # 10:is length of your sublist
5.5
python2.*:
>>> from __future__ import division # to get float division like python3
>>> sum(A[:10]) / 10 # 10:is length of your sublist
5.5

I'm going to strongly suggest removing the Python 2 answer, since Python 2 is no longer supported, and should (thus) not be (promoted to be) used anymore. – 9769953 Jan 30 '20 at 08:58
