Collect lines in a file

[mlieqo]

Collect all messages in intermediate and append to final data only when there is a timestamp (and there is data in intermediate)

intermediate = []
finalData = []
file = open('sample.txt', 'r', encoding="utf8")
for lines in file:
    if startsWithDate(lines) and intermediate:
        finalData.append(' '.join(intermediate))
        intermediate.clear()
    intermediate.append(lines)
