Syntax error problem: please help

[noob92]

I'm using python to write a program that, when given a list of random numbers, sorts them from lowest to highest then it asks the user for a number and it checks that number's place in the sorted list if the number is present, but i keep getting a syntax error on an "if" statement line near the end. is it because i'm not allowed to look up a number in the sorted list? here's my program with a list of example numbers (highlighted in bold is where i get the syntax error):

import random
def sort_array2_4():
    unsorted_array = random.sample(xrange(1000), 10)
a=[93,84,200,513,46,1,45,334,92,96,156,82,92,46,]
def bubblesort(a):
    for swap in range(len(a)-1,0,-1):
         for index in range(swap)
             if a[index] > a[index + 1]:
               a[index], a[index + 1] = a[index + 1], a[index]
    return a
while(more==True):
    num=str(input("Enter a number to search for in list.\n")
    if (num in bubblesort(a)):
        print num + "is in list at number: ", bubblesort(a).index(num)
    else:
        print num + "is not recognized in list"

print num + "is not recognized in list"

I'm pretty sure i have all of my indents in the right place, but i can't show you here.

If fixed that. Not just because I can... You'll learn to use code tags as you go along. The instructions are in the "Posting Guidelines" panel and sticky.

thanks man, so any ideas on my problem?

Great job! you were very close. next time include error message, ok?

    return a
more = True  # must assign before reference
while(more==True):
    num=input("Enter a number to search for in list.\n")
    # one too few parens caused syntax error no next line
    # need the int anyway
    b = bubblesort(a)  # use lots of variables for debugging
    print b   # debug "trap"
    if (num in b):
        # print will convert to printable, so you don't have to
        print num, "is in list at number: ", a.index(num)
    else:
        print num, "is not recognized in list"

Oh my god, thanks a ton for the help! that worked great! i will definitely need to remember this stuff, thanks!

Maybe you know this but the Python list object has an in place sort method:

a=[93,84,200,513,46,1,45,334,92,96,156,82,92,46,]
a.sort()
print a
>>> [1, 45, 46, 46, 82, 84, 92, 92, 93, 96, 156, 200, 334, 513]

Yeah, I was going to tell him about that. Writing a sort routine is great exercise, though.
