Files handling and lists

[gonzo620]

im creating a program that will tell me what the climate is in a city in the summer and in the winter based on it's latitude. I'm doing this by adding them to separate lists first. How can I have my program skip the first line because it is the header.

my code

with open('cities.txt','r', encoding = 'cp1252') as f:
    
    season = input('Will you take your holiday in the summer or winter? ')
    temp = input('Do you want to go to a destination that is warm or cold? ')

    summercold = []
    summerwarm = []
    winterwarm = []
    wintercold = []


    for line in f:
        lat = int(line[0:2])
        
        if lat > 66:
            summercold.append(line)
            wintercold.append(line)
            
        elif lat > 35 and lat < 66:
            if line[5] == N:
                summerwarm.append(line)
                wintercold.append(line)
            elif line[5] == S:
                summercold.append(line)
                winterwarm.append(line)
                
        else:
            summerwarm.append(line)
            winterwarm.append(line)

Error:
    lat = int(line[0:2])
ValueError: invalid literal for int() with base 10: 'La'

I'm getting an error because the first line is a string so line[0:2] can't convert it into an integer. How can I skip the first line?
