erratum: chapter 3

• Page 69: in the code for linear search, an indentation is needed in the else statement part. It works well for items that are in the searched list, but for items that aren't in the searched list, it goes to an infinite loop and needs to interrupt the kernel. The code on page 69 is:

def LinearSearch(list, item):
    index = 0
    found = False
# Match the value with each data element
    while index < len(list) and found is False:
        if list[index] == item:
            found = True
    else:
        index = index + 1
    return found

The code above should be indented like below:

def LinearSearch(list, item):
    index = 0
    found = False
# Match the value with each data element
    while index < len(list) and found is False:
        if list[index] == item:
            found = True
        else:
            index = index + 1
    return found

Codes in here are OK.

We have update the readme with the correct code and so we'll be closing this issue.
Nice work, we appreciate the feedback!
