How to a read large file, line by line in Python
10 answers
I am new in python and I am trying to print a list line by line.
fp = open(filepath) # Open file on read mode
lines = fp.read().split("n") #Create a list with each line
print(lines) #Print the list
for line in lines:
print(line) #Print each line
fp.close()
But it's printing in one line.
The contents of the text file are
peat1,1,11345674565,04-11-2018
peat2,0,11345674565,05-11-2018
peat3,1,11345674565,06-11-2018
peat4,0,11345674565,07-11-2018
And it is printing as
peat1,1,11345674565,04-11-2018 peat2,0,11345674565,05-11-2018 peat3,1,11345674565,06-11-2018 peat4,0,11345674565,07-11-2018
The environment is -- Python 3.4 and running under Apache through cgi-bin
Any help is highly appreciated.

It should work. Perhaps your file only has 1 line? How many elements does yourlineslist contain? Can you include a portion of the file as well?

@RedCricket Before posting here I have explored 3-4 similar posts but not the one which you mentioned. The reason is my txt file has got only 4 lines so it's not a large file.

@PrithvirajMitra your approach should work so there is something you aren't showing us. You really need to provide a Minimal, Complete, and Verifiable example, and at the very least, the output you are seeing.

With large files, you are better off reading files line by line, like so:
with open('filename') as file:
for line in file:
print(line)
I suggest this approach with with, which handles closing the file pointer itself.

There approach should work, though, even if it is less than ideal. And in any event, if this were the answer, then it would be a clear duplicate and should be closed

But that doesn't answer the purported question, because the OP claims the approach doesn't work, and indeed if it doesn't, then this approach wouldn't work either. The OP needs to add more details and a MCVE
