That's pretty much it.. I'm guessing you are assuming your file has
one word per line?  I took a shot at it, without using the regex
module:

file = open('spyware')

my_string = 'uzi'
length = len(my_string)
words = []

for line in file :
    chunks = line.strip().split()
    for chunk in chunks :
        x = 0
        for char in my_string :
            x = chunk.rfind(char,x)
        if x > 0 :
            words.append(chunk)

print '\n'.join(words)


or with the re module:

import re

text = open('words.txt').read()
pattern = '\S*u\S*z\S*i\S*'
stuff = re.findall(pattern,text)
count = len(stuff)

print "Found %d words :" % (count)
print "\n".join(stuff)
