How do I read a random line from one file?

Question

Is there a built-in method to do it? If not how can I do this without costing too much overhead?

Answer 1

This may be bulky, but it works I guess? (at least for txt files)

import random
choicefile=open("yourfile.txt","r")
linelist=[]
for line in choicefile:
    linelist.append(line)
choice=random.choice(linelist)
print(choice)

It reads each line of a file, and appends it to a list. It then chooses a random line from the list. If you want to remove the line once it's chosen, just do

linelist.remove(choice)

Hope this may help, but at least no extra modules and imports (apart from random) and relatively lightweight.
