[Tutor] 2 problems in a small script

[Dick Moores]

**Blush**

These lines were in my last post in this thread:

"Done. I had no idea set could be used that way! With a couple of 
modifications, I used your ideas in both <buggy_For_Web5b.py> and 
<getCrew_ForWeb2.py> (see the thread I started, 
<http://www.nabble.com/An-idea-for-a-script-tf4603558.html#a13149808>)."

They should have read:

"Done. I had no idea set could be used that way! With a couple of 
modifications, I used your ideas in both 
<http://www.rcblue.com/Python/buggy_For_Web5b.py> and 
<http://www.rcblue.com/Python/getCrew_ForWeb2.py> (see the thread I 
started, 
<http://www.nabble.com/An-idea-for-a-script-tf4603558.html#a13149808>)."

But also, though I'm very glad Ian showed me how to use sets in that 
magic way, I had forgotten that a list comprehension can be much more 
succinct:

lstB = [ word for word in lstA if all(char in astr for char in word) 
]  in "buggy" (line 11)

lstD = [ word for word in lstC if all(char in astr for char in word) 
] in "getCrew" (line 26)

(Thanks to Kent, I believe.)
