Finding number of values in a column between 2 specific values

I'm very new to python and I am wanting to simply find out the number of values in a list between two latitudes.

I thought a simple if statement would suffice, but apparently not. My coding looks like this:

if lat < 62 & lat > 58:
    z = len(lat)
    print z

I then want to be able to get rid of repeated numbers. So how would I do that?

& is a bitwise AND operator. You should instead use and.

Alternatively you can use chained operators as shown below:

if 58 < lat < 62:
    # do whatever you need to...

What you're actually trying to do is calculate how many of your latitudes are within the range (58, 62). In that case you can do z = sum(58 < i < 62 for i in lat). This makes use of the fact that in Python True is equal to 1 and False is equal to 0. So if an element is within the range then it'll count as 1 and when you sum them all then only True (1) values will count up.
