ugh, fine. im coming around to python...

string stuffs:

"s1 = ' ' Empty string 
s2 = "spam's" Double quotes 
block = """ ... """ Triple-quoted blocks 
s1 + s2 Concatenate, 
s2 * 3 repeat 
s2[i], Index, 
s2[i:j], slice, 
len(s2) length 
"a %s parrot" % 'dead' String formatting 
for x in s2, Iteration, 
'm' in s2 membership"

string codes:
"
%s          String (or any object's 
print format) 
%X          Hex integer (uppercase) 
%c          Chapter %e          Floating-point format 1a 
%d          Decimal (int) %E          Floating-point format 3 
%i          Integer %f          Floating-point format 3 
%u          Unsigned (int) %g          floating-point format 4 
%o          Octal integer %G          Floating-point format 5 
%x          Hex integer %%          Literal % 
"

lists:

>>> L = ['spam', 'Spam', 'SPAM!'] 
>>> L[2]                                # offsets start at zero 
'SPAM!' 
>>> L[-2]                               # negative: count from the right 
'Spam' 
>>> L[1:]                               # slicing fetches sections

"No amount of reading of woodworking magazines is going to turn a novice into a master woodworker. For that to happen, you have to have talent, of course, but also spend years examining furniture, taking furniture apart, building new pieces, learning from your mistakes and others' successes. The same is true in programming. The role of textbooks is to give a bird's eye view of the kinds of problems and appropriate solutions, to show some of the basic tricks of the trade, and, finally, to motivate the frustrated beginner by showing some of the nicer pieces of work others have built.
