average of values in dict with use of for

[Daromir]

Hello,

Newbie here, so im sorry for all mistakes related to posting this.
I recently went through Udemy "Complete Python Course from Basics to Brilliance in HD" and now im looking for ways to hone my knowledge.
Was going through some homework tests from a friend and wondered if i could get help in finishing this one:

dic={"123/2018":8,"124/2017":6,"125/2018":7,"126/2017":9}
del dic["124/2017"]
dic["435/2018"]="6"
print(dic)

What test asks now is to print average of values in dic with use of for.

All suggestions/comments are welcome.
If it is not violating any rule, i would expand this thread with my future problems.
Thank you all in advance.

please, show what have you tried in using for loop to iterate over dict values.
if you need you can check out tutorials section:
https://python-forum.io/Thread-for-loops
https://python-forum.io/Thread-Basic-Dictionaries

https://docs.python.org/3/tutorial/datas...ctionaries

Look under 5.6 Looping Techniques

And use better titles for your threads. "I'm a helpless newbie" type topics just make me want to ignore the post.

As this is homework I will provide ways without for-loop. This may or may not give an ideas.

>>> d = {'ham': 7, 'spam': 42}
>>> sum(d.values()) / len(d.values())
24.5

There is mean() in statistics module, so one can do:

>>> from statistics import mean
>>> mean(d.values())
24.5

Something like this came to my mind first, but i cant figure out working way that involves for, since that is what is asked for.

I guess i failed to find what i need in your links, but that stuff will come in handy for sure.
Is there a way i can change title thread?

Current state of things

dic={"123/2018":8,"124/2017":6,"125/2018":7,"126/2017":9}
del dic["124/2017"] #ili recnik.pop("124/2017")
dic["435/2018"]=6
print(dic)

med=sum(dic.values())/len(dic)
print(med)

Your original post says "What test asks now is to print average of values in dic with use of for."

Is the for loop a requirement? If so, you solution is not correct.

Last post was sort of a test to see if i can comunicate properly on this forum. Which i guess i can not edit now.

dic={"123/2018":8,"124/2017":6,"125/2018":7,"126/2017":9}
del dic["124/2017"] #ili dic.pop("124/2017")
dic["435/2018"]=6
print(dic)

med=0
for i in dic.values():
    med+=i
    
med=med/len(dic)
#med=sum(dic.values())/len(dic)
print(med)

My personal subjective opinion is that for-loop is redundant, but it can be easily accommodated into code:

>>> d = {'ham': 7, 'spam': 42}
>>> sum(i for i in d.values()) / len(d.values())
24.5
