Python: How to count the desired data values in a csv file

I want to count only the numbers between 500 and 550 in the csv file, how do I enter them? I used a Pandas module, and I want to get the result of a strong number (count) x 25 at the end, how should I input it?

*Python 3.8.5 Anaconda

def surface_area_of_cotter(data_set,x_coordinate,y_coordinate): 
    dictio = {}
    count = 0
    s = pd.Series(range(500,550))
    data_set = pd.read_csv("elevation_data_dam.csv", header=None)
    for s in data_set:
        count += 1
        if s in dictio:
            dictio[int(s)] += 1
        else:
            dictio[int(s)] = 0
    if count ==0.0:
        return 0
    else:
        return (count*25)

I can't upload the csv file, so I'll upload a screenshot.

It looks like this, and it's about 883 rows x 1189 columns
