9.7. The Slice Operator¶
A substring of a string is called a slice. Selecting a slice is similar to selecting a character:
The slice operator
[n:m] returns the part of the string from the n’th character
to the m’th character, including the first but excluding the last. In other words, start with the character at index n and
go up to but do not include the character at index m.
behavior may seem counter-intuitive but if you recall the
range function, it did not include its end
If you omit the first index (before the colon), the slice starts at the beginning of the string. If you omit the second index, the slice goes to the end of the string.
There is no Index Out Of Range exception for a slice. A slice is forgiving and shifts any offending index to something legal.
