It appears that the biggest issue is with lines immediately following your with statement. Those should be indented to be part of the context manager scope.

elif engine == "example2":
    filepath = "list.txt"
    with open(filepath) as fp:
        line = fp.readline() # <--- note indent
        count = 1            # <--- note indent
        while line:
            search = example2(engine)
            request = partial(search.search_for, line.strip())
            all = p.map(request, pages)
            line = fp.readline()
            count += 1

Here you have 2 intent mistakes.copy this code and try it

if engine == "example1":
     search = example1(engine)
     request = partial(search.search_for, string)
     all = p.map(request, pages)

1. In elif there is one space before the line

elif engine == "example2":
    filepath = "list.txt"

2.After the next line With open you need to leave 4 spaces

    with open(filepath) as fp:
        line = fp.readline()
    count = 1
    while line:
        search = example2(engine)
        request = partial(search.search_for, line.strip())
        all = p.map(request, pages)
        line = fp.readline()
        count += 1
    input(" press close to exit ")
