I am working on an assignment in college using RUR-PLE as a starting program. I don't know if you know what that is or not, but I was wondering how to use it? I enter in this code:

x = input("How many beepers are in this maze?")
def place_all():
    repeat(put_beeper,totalBeepers)
def final_move():
    if front_is_clear():
        place_all()
        move()
    elif left_is_clear():
        turn_left()
        place_all()
        move()
    elif right_is_clear():
        turn_right()
        place_all()
        move()
    else: turn_around()
    place_all()
    move()
def turn_right():
    repeat(turn_left,3)
def turn_around():
    repeat(turn_left,2)
def move_around():
    numberOfBeepers = 0
    if left_is_clear():
        turn_left()
        move()
    elif front_is_clear():
        move()
    elif right_is_clear():
        turn_right()
        move()
    else:
        turn_around()
    while on_beeper():
        pick_beeper()
        numberOfBeepers += 1
    return numberOfBeepers


countMoreBeepers = True
countBeepers = 0
totalBeepers = amntOfBeepers
while countMoreBeepers:
    #move_around()
    countBeepers = countBeepers + move_around()
    print countBeepers
    if countBeepers == totalBeepers:
        print 'I have so many delicious muffins! ^.^'
        final_move()
        countMoreBeepers = False

turn_off()

It keeps telling me that I cannot use the input string in the beginning. Is that because I have other variables or code in there that prevents the input from working? Is there a completely different input function I'm supposed to use? Please help!

input() function means you can input int number or string with " ":
like:

a=input()
"hello"
a
'hello'
a=input()
100
a
100

your code except a int number but not a string var.

Depending on your version of Python: 2.x or 3.x this applies:
2.x:

x = raw_input("Beeps: ") #gets the input as a string
try:
    x=int(x) #tries to convert it to an int
except Exception as e:
    print "Not an int." #if it fails an error message is shown

3.x:

x = input("Beeps: ") #gets the input as a string
try:
    x=int(x) #tries to convert it to an int
except Exception as e:
    print ("Not an int.") #if it fails an error message is shown

This is a simple validation to see if the inserted element is a string or an int. Put it after the x = input() part of your program, and see the results.
