how to get result from many list in same line in python

Question

I have three list:

alist=[1,2,3,4,5]
blist=['a','b','c','d','e']
clist=['@','#','$','&','*']

I want my output in this format:

1 2 3 4 5
a b c d e
@ # $ & *

I am able to print in correct format but when i am having list with many elements it's actually printing like this:

1 2 3 4 5 6 ..........................................................................
................................................................................

a b c d e ............................................................................
......................................................................................

@ # $ & * .............................................................................
.......................................................................................

but I want my output like this:

12345....................................................................
abcde...................................................................
@#$&*...................................................................

............................................................... {this line is from alist}
................................................................ {this line is from blist}
................................................................ {this line is from clist}

Are we talking about a fixed width here or about a variable width depending on how wide the terminal screen is? — Martijn Pieters, Dec 11 '15 at 07:47
What the dots are supposed to represent? What "this line is from alist" means? I don't see any line with dots in any of your lists, so it seems you expect your code to do something more than what you described in your question. — Lav, Dec 11 '15 at 07:50
dots represent more elements... and its because of width of terminal — mohammad shahbaz Khan, Dec 11 '15 at 07:52
@mohammadshahbazKhan: So split a list by the width of terminal? — Remi Guan, Dec 11 '15 at 08:05

Try the following:

term_width = 80
all_lists = (alist, blist, clist)
length = max(map(len, all_lists))
for offset in xrange(0, length, term_width):
    print '\n'.join(''.join(map(str, l[offset:offset+term_width])) for l in all_lists)

This assumes terminal width is 80 characters, which is the default. You might want to detect it's actual width with curses library or something based on it.

Either way, to adapt to any output width you only need to change term_width value and the code will use it.

It also assumes all elements are 1-character long. If it's not the case, please clarify.

If you need to detect terminal width, you may find some solutions here: How to get Linux console window width in Python

what if we have three long variable instead of list – mohammad shahbaz Khan Dec 11 '15 at 08:08
@mohammadshahbazKhan This code works with both strings and one-character lists equally. It won't work with lists composed of items with *different* size, as in this case you'll need to do some smart wrapping. – Lav Dec 11 '15 at 08:11
Use `import os; term_width = os.get_terminal_size().columns` to get the terminal width. – Remi Guan Dec 11 '15 at 08:13
@KevinGuan, that only works in Python 3.x. I have added a reference to a relevant question which has a number of more generic solutions. – Lav Dec 11 '15 at 08:14
Oh, see that just now. – Remi Guan Dec 11 '15 at 08:15
how can i give one line gap between them .. only when new line starts for alist,blist and clist – mohammad shahbaz Khan Dec 11 '15 at 08:22
