'''
The aim of this challenge is, given a dictionary of people's online status, to count the number of people who are online.

For example, consider the following dictionary:

statuses = {
    "Alice": "online",
    "Bob": "offline",
    "Eve": "online",
}
In this case, the number of people online is 2.

Write a function named online_count that takes one parameter. The parameter is a dictionary that maps from strings of names to the string "online" or "offline", as seen above.

Your function should return the number of people who are online.

def online_count(s={}):

    online = 0
    offline = 0
    for k in list(s.keys()):
        if   s[k] == "online":
             online += 1
    return online        

print(online_count({"Alice": "online",
    "Bob": "offline",
    "Eve": "online",}))
