How do I remove extra spaces between my conclusions?

Here is the first code that printed my output in order:

 import csv
 import random
 import os.path


 def filename ():

     filename = 'filename.txt'
     with open ("filename.txt", "r") as data_file:

        for line in data_file.readlines():
           line = line.strip().split()
           print (line [0], line [1], line[2])

This was the result:

 1  63075384    0.781952678
 1  212549126   0.050216027
 2  35003118    0.027205438
 2  230357107   0.065453827
 3  77023025    0.098224352
 3  225622058   0.785312636

Then I wanted to randomize my conclusion. So here is the second code where I did it:

 import random
 with open('filename.txt') as fin:
    lines = list(fin)

 random.shuffle(lines)
 for line in lines:
    print (line)

Here is the result. Which adds extra white space between each line:

2   35003118    0.027205438

3   77023025    0.098224352

2   230357107   0.065453827

1   212549126   0.050216027

3   225622058   0.785312636

1   63075384    0.781952678

My desired output:

2   35003118    0.027205438
3   77023025    0.098224352
2   230357107   0.065453827
1   212549126   0.050216027
3   225622058   0.785312636
1   63075384    0.781952678

How can I change the second code shown above so that I can print my output without any extra spaces?

I know this may seem like a duplicate question, but the fact is that I have searched the internet and I cannot find a solution to this problem. I'm happy to clarify everything. Thank.

Your lines contain a newline character at the end of them, so in this loop:

for line in lines:
    print (line)


it will print a newline on the line line

. Just uncheck line

to remove the newline:

for line in lines:
    print (line.strip())

Try the following:

import random

with open('filename.txt') as fin:
    lines = list(fin)
    random.shuffle(lines)
    for line in lines:
        print(line, end='')


Setting end=''

in print()

avoiding printing a new line.

For more information see the Python docs atprint()
