I think the question is how to sum up the "s1" values from the dictionaries. The question is not clear at all. — Lomtrur, Feb 22 '19 at 07:05
To find the sum of the values of s1 across 3 dictionaries that is to add 10+20+30 — Jacob Nirappel, Feb 22 '19 at 07:42

If you want to add all the values of s1, you need to iterate over the values() of dictionary students.

students={
    1: {"pup1": "001", "s1": 10, "s2": 20},

    2: {"pup2": "124", "s1": 20, "s2": 30},

    3: {"pup3": "125", "s1": 30, "s2": 40}}

sum1 = 0
for data in students.values():
    sum1 += data['s1']

avg = sum1 / len(students)

print(sum1)
print(avg)

Perhaps he meant to add values `in` the key `s1` not the `sum` of those values, separately. – DirtyBit Feb 22 '19 at 07:16
@user5173426: PERHAPS!! Because the question is not clear as to what exactly the OP needs. – eiram_mahera Feb 22 '19 at 07:19
@ eiram_mahera:This is what i needed, also can you help me to find the average in similar fashion – Jacob Nirappel Feb 22 '19 at 07:55
@JacobNirappel: As this is what you were looking for please mark the answer correct. – eiram_mahera Feb 22 '19 at 09:06
