I have this psuedocode:

FUNCTION initialize

FOR row = 1 to num_items

get random number for the list

ENDFOR

ENDFUNCTION initializeFUNCTION show

FOR row = 1 to num_items

show output: list(row)

ENDFOR

ENDFUNCTION showFUNCTION sort

FOR pass = 1 to num_items

posn = 1

sorted = True

WHILE posn < num_items

IF list(posn) > list(posn + 1)

swap list(posn) with list(posn + 1)

sorted = False

ENDIF

increment posn

ENDWHILE

IF sorted

Exit the FOR loop

ENDIF

perform show

ENDFOR

ENDFUNCTION sortnum_items = MAX

define a numeric list of size num_itemsperform initialize

perform show

perform sort

That I need to translate into python. so far this is what I have:

```
from random import randint
list_num=[]
row=0
num=0
num_items=15
def initialize():
for row in range(0,num_items):
number=randint(1,1000)
list_num.append(number)
row +=1
def sorter():
posn=1
for num in range(0,num_items):
srtd=0
while posn<num_items:
if list(posn) >list(posn+1):
a= list_num.index(list_num(posn))
b= list_num.index(list_num(posn+1))
list_num[b],list_num[a]=list_num[a],list_num[b]
srtd=1
posn+=1
else:
posn+=1
if srtd==0:
break
print list_num
initialize()
print list_num
sorter()
```

But I keep getting this result:

Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)]

Type "help", "copyright", "credits" or "license" for more information.

Any help or advice you have to offer would be a great deal of help.

Thanks,
