Some Notes on Strings

Here are some string operations that you might find useful.

string[i]

Get the ith element of the string. Indices start at 0.

'Hello'[0] => 'H'

'Hello'[4] => 'o'

'Hello'[5] => An error!

list(string)

Convert a string to a list of characters.

list('Hello') => ['H', 'e', 'l', 'l', 'o']

string.join(list-of-strings, separator)

Join the elements of list-of-strings, putting separator between subsequent elements.

Note: To use the operations whose name begins with string, make sure to use import string.
