If statement is not printing anything in python [closed]

I have to loop through data including 'visit_counts' affiliated with a 'city'

I made an if statement in a for loop; it doesn't give any errors but it's also not printing what I want. Am I doing/understanding something wrong?

for v in visits_19:
    if v == 'West Lafayette':
        wl_sum = visits_19['raw_visit_counts'].sum()
        print(wl_sum)
    elif v == 'Lafayette':
        l_sum = visits_19['raw_visit_counts'].sum()
        print(l_sum)
    elif v == 'Dayton':
        d_sum = visits_19['raw_visit_counts'].sum()
        print(d_sum)
    elif v == 'Batle Ground':
        bg_sum = visits_19['raw_visit_counts'].sum()
        print(bg_sum)

Here is an example:

visit_19 = {'city': ['West Lafayette','Lafayette','Lafayette','West Lafayette','West Lafayette','Dayton'],
         'visit_counts' : [100,10,151,20,2,5]}

df = pd.DataFrame(visit_19)
g = df['city']

for g in visit_19:
    if g == 'West Lafayette':
        wl_sum = df['visit_counts'].sum()
        print(wl_sum)
    elif g == 'Lafayette':
        l_sum = df['visit_counts'].sum()
        print(l_sum)
    elif g == 'Dayton':
        d_sum = df['visit_counts'].sum()
        print(d_sum)

What I want to do: When the city == 'West Lafayette', calculate the sum of the visit that have West Lafayette as their city.
