how do you delete the line with the biggest number from a text file python?

Question

with open('winnernum.txt', 'r') as b:
  data = b.readlines()
  gone=(max(data))
  print(gone)
with open("winnernum.txt","r") as h:
  del gone

I've tried this and other variations of this code in python but it still won't delete. I need to print the top 5 largest numbers from a text file.

I've attempted using this before:

with open('winners.txt', 'r') as b:
  data = b.readlines()
  gone=(max(data))
  print(gone)
import heapq
print(heapq.nlargest(5, winner))

but that doesn't always pick the top 5 numbers and tends to select them at random. Please help!

Answer 1

Here is a simple solution:

from heapq import nlargest

with open("winnernum.txt", "r") as f:
    numbers = [float(line.rstrip()) for line in f.readlines()]
    largest = nlargest(5, numbers)

print(largest)

Answer 2

Try this:

from contextlib import closing

with closing(open('winners.txt', 'r')) as file:
    gone = max(map(lambda x: x.rstrip('\n'), file.readlines()))

print(gone)
