我想在比赛前后打印该行

Question

I am wanting to create a .py file that can open a .txt document and read in the data, split it into words, then I would like to be able to search for a date and time. The time can vary and may not be exact so it could fall in between two times. I would like to print the two lines that fall before and after the searched date/time.

I am using this so far:

temp_list =[]
open_file = open(temp_data, "r")
contents = open_file.readlines()[57:] #skipping first 57 lines.
for i in range(len(contents)):
words = contents[i].split()
if (len(words) == 43) and (words[0] == date) and (words[1] < time): #using 43 will read/print only lines that have 43 words in them as they are the lines with important data.
    print words[0], "|", words[1], "|", words[12],  "F"

I am completely new to coding and have looked everywhere but am still not able to find anything. Any help is appreciated, thank you!

Answer 1

You need a function that will return True if the line is a match. Looks like your if statement is doing that. If it returns True, then print the lines contents[i-2:i+2] .
