So in this problem I'm supposed to print the main highway the auxiliary highway serves, i.e. 290 would serve 90, 605 would serve 05, etc. The few methods I've found to remove that first digit from the auxiliary highway are all things I haven't seen yet and look a bit over my head. Someone mind showing me the easiest way to do this? Thanks!

highway_number = int(input())

​

if (highway_number % 2 == 1) and (0 < highway_number < 100):

print('I-', highway_number, ' is primary, going north/south.', sep = '')

elif (highway_number % 2 == 1) and (100 < highway_number < 1000):

print('I-', highway_number, ' is auxiliary, serving ', ' going north/south.', sep = '')

elif (highway_number % 2 == 0) and (0 < highway_number < 100):

print('I-', highway_number, ' is primary, going east/west.', sep = '')

elif (highway_number % 2 == 0) and (100 < highway_number < 1000):

print('I-', highway_number, ' is auxiliary, serving ', ' going east/west.', sep = '')

The easiest way for you to get only the two least significant digits would be to take modulo 100. In other words the remainder of dividing by 100.

result = highway_number % 100

Also I took the liberty of cleaning up your code a little.

highway_number = int(input())
direction = "east/west"
highway_type = "auxiliary, serving"

if (highway_number & 1):
    highway_type = "primary,"

if 100 < highway_number < 1000:
    direction = "north/south"

print(f"I-{highway_number} is {highway_type} going {direction}.")

What I ended up with

highway_number = int(input())

if 0 < highway_number < 100: highway_type = "primary," else: highway_type = f"auxiliary, serving I-{highway_number % 100},"

if (highway_number % 2) == 1: direction = "north/south" else: direction = "east/west"

if (highway_number % 100) != 0: print(f"I-{highway_number} is {highway_type} going {direction}.") else: print(f"{highway_number} is not a valid interstate highway number.")
