Here's pseudo code for what I would like to do:

for char in some_long_string:
    if char == some_char:
        for char in some_long_string: <--- using same iterator as above
            # continue to pull chars from some_long_string
            # until some conditions are met

    # repeat above pattern again several times in the loop,
    # with iterator access potentially nested

One solution might be to convert some_long_string into a generator

Is there a simple way wrap a string as a generator or do I need to

it = iter(some_long_string)
for char in it:
    if char == some_char:
        for char in it:
            # continue to pull chars from some_long_string
            # until some conditions are met

    # repeat above pattern again several times in the loop,
    # with iterator access potentially nested
