python - unorderable types: float() <= lists() -

i cant code compare 2 numbers want see if number smaller if want print "is smaller" if not want end. lat.csv fill of numbers 52.6169933 , user input similar.

import csv lat = float(input("enter location latitude")) lat = lat - 0.01862 x = 1 open('lat.csv') f:     reader = csv.reader(f)     arraylat = list(reader) if float(lat) <= arraylat[x]:     print("is smaller") print("end")  traceback (most recent call last):   file "c:/users/ryan/documents/python/map/test.py", line 8, in <module>     if float(lat) <= arraylat[x]: typeerror: unorderable types: float() <= list() 

i see couple of issues example code put up, should able fix if go through python tutorial beginners. assuming understand problem,

with open('lat.csv') f:     reader = csv.reader(f)      row in reader:         row = row.split(',')         is_smaller = false         val in row:             if(lat <= float(val)):                print("is smaller")                is_smaller = true                break         if is_smaller == true:             break print("end")    

the is_smaller flag check if value larger input found, , if is, stops searching , prints "is smaller" helpful read on csv.
