Any Python developers on here? Or UX developers?

import csv
callsign = input("Please enter the callsign: ")
with open('stations.csv', 'r') as f:
    # usually see it recommended to use `with` when using open
    # not super important and won't bite you unless you're using
    # a different python implementation but it is good practice
    stations = csv.reader(f)

# make a flag so you know if you find it
found_station = False
for row in stations:
    if callsign == row[0]:
        # try using format strings when combining strings
        # you can also use tuple unpacking, which is pretty neat
        # below is the same as
        # print ("{} = {}".format(row[0], row[1]))
        # or 
        # print (row[0] + " = " + row[1]) )
        print ("{0} = {1}".format(*row))
        # update our flag
        found_station = True
        # terminate loop early so we don't check rest of list
        break
# check our flag to see if we managed to find what we wanted
if not found_station:
    print("Station '{}' not found".format(callsign))

Bit of reading:
with statement
format string
tuple unpacking

you could also use a "for-else" loop, but I don't know many people who use them so they just end up looking weeeeeeeird

import csv
call_sign = input("Please enter the callsign: ")
with open('stations.csv', 'r') as f:
    stations = csv.reader(f)

for row in stations:
    if call_sign == row[0]:
        print ("{0} = {1}".format(*row))
        break
else:
    print("Station '{}' not found".format(callsign))
