You can define getLines in terms of the readline file method, which does
return new data when it is available.

def getLines(f):
    lines = []
    while True:
        line = f.readline()
        if line == '':
            break
        lines.append(line)
    return lines

or, more succinctly:

def getLines(f):
    return list(iter(f.readline, ''))
