I have a the string 'Hello', I need to find out what characters occupy which indexes.
Pseudo-code:
string = 'Hello'
a = string.index(0)
b = string.index(4)
print a , b
a would be 'H' and b would be 'o'.

String (str) in Python is a sequence type, and thus can be accessed with []:
my_string = 'Hello'
a = my_string[0]
b = my_string[4]
print a, b # Prints H o
This means it also supports slicing, which is the standard way to get a substring in Python:
print my_string[1:3] # Prints el

In anticipation of the lack of Python experience in the guy asking this question, I might add that it might not be a good idea to name a variable after an existing module,
string in this case.
NullUserException
@Jim a deprecated module nonetheless
I think he is asking for this
for index,letter in enumerate('Hello'):
print 'Index Position ',index, 'The Letter ', letter
And maybe we want to explore some data structures
so lets add a dictionary - I can do this lazily since I know that index values are unique
index_of_letters={}
for index,letter in enumerate('Hello'):
index_of_letters[index]=letter
index_of_letters
