You already know about str.join ()
Slicing
b=['s','p','a','m']
b [ : 1 ]
['s']
b [ : 2 ]

Also, consider

range ( 4 )
[ 0, 1, 2, 3, 4]

You can use the standard library to generate the

Probably not, since they aren't really Python terms, so I'll be guessing what
they are.

That's not all that's in the byte-code file, but this is 98% of what you

The presence of an if statement cannot affect whether or not a continue
can work. If you give a concrete code example, somebody will be able to
identify the confusion.
