Pretty Print a List

Question

I am trying to pretty print a list but unfortunately, I am having a little trouble with it. So the code goes like this:

from pprint import pprint
deck = []
for s in ("CDHS"):
    for v in ("A23456789TJQK"):
        deck.append(v+s)
print(deck)
pprint(deck, width=20)

I am trying to print the deck like this:

AC 2C 3C 4C 5C 6C 7C 8C 9C TC JC QC KC
AD 2D 3D 4D 5D 6D 7D 8D 9D TD JD QD KD
AH 2H 3H 4H 5H 6H 7H 8H 9H TH JH QH KH
AS 2S 3S 4S 5S 6S 7S 8S 9S TS JS QS KS

but It is printing like this :

['AC',
 '2C',
 '3C',
 ......
 .....

please tell me how to fix it! Thanks

If you search in your browser for "Python print tutorial", you'll find references that can explain this much better than we can manage here. — Prune, Sep 26 '19 at 17:49
There is no magic pprint function that will do that for you. You have to do it yourself with a print tutorial in hand. — RickyA, Sep 26 '19 at 19:09
If you object to the `[...]` brackets then stop using `pprint`, simply use plain old `print`. Just because you're trying to prettyprint something, doesn't follow that you must use `pprint` module. — smci, Oct 02 '19 at 20:45
`for i in range(0, len(deck), 13): print(' '.join(deck[i:i+13]))` — inspectorG4dget, Oct 02 '19 at 20:48
`pprint(deck, compact=True)` does give you 80-character lines, but you still get the unwanted parentheses and quotes. So don't use pprint module. — smci, Oct 02 '19 at 20:55

There are some good ideas [here](https://stackoverflow.com/q/30451252/4014959), but beware the Python 2 code in some of those answers. Eg, instead of `xrange` use `range` in Python 3. — PM 2Ring, Oct 04 '19 at 08:22

Try this out. You can tweak with various width values to suit your requirement.

>>> pp = pprint.PrettyPrinter(width=38, compact=True)
>>> pp.pprint(deck)
['AC', '2C', '3C', '4C', '5C', '6C',
 '7C', '8C', '9C', 'TC', 'QC', 'JC',
 'KC', 'AD', '2D', '3D', '4D', '5D',
 '6D', '7D', '8D', '9D', 'TD', 'QD',
 'JD', 'KD', 'AH', '2H', '3H', '4H',
 '5H', '6H', '7H', '8H', '9H', 'TH',
 'QH', 'JH', 'KH', 'AS', '2S', '3S',
 '4S', '5S', '6S', '7S', '8S', '9S',
 'TS', 'QS', 'JS', 'KS']

This code doesn't give the desired output shown in the question. – PM 2Ring Oct 04 '19 at 08:09
@PM2Ring read the first line of the answer. I've clearly mentioned that the OP can tweak with various width values to suit their requirement. – taurus05 Oct 04 '19 at 14:07
How does tweaking the width get rid of the quotes, commas, and brackets? – PM 2Ring Oct 04 '19 at 17:03

Lazy way, just print cards directly from within your nested loops:

>>> for s in ("CDHS"): 
...     for v in ("A23456789TQJK"): 
...         print(v+s, end=' ') 
...     print() 
...
AC 2C 3C 4C 5C 6C 7C 8C 9C TC QC JC KC 
AD 2D 3D 4D 5D 6D 7D 8D 9D TD QD JD KD 
AH 2H 3H 4H 5H 6H 7H 8H 9H TH QH JH KH 
AS 2S 3S 4S 5S 6S 7S 8S 9S TS QS JS KS

More Pythonic way, split your deck into chunks and tabulate:

>>> from tabulate import tabulate  # pip install tabulate
>>> from wimpy import chunks  # pip install wimpy
>>> deck2 = chunks(deck, len("A23456789TQJK"))
>>> print(tabulate(deck2, tablefmt="plain"))
AC  2C  3C  4C  5C  6C  7C  8C  9C  TC  QC  JC  KC
AD  2D  3D  4D  5D  6D  7D  8D  9D  TD  QD  JD  KD
AH  2H  3H  4H  5H  6H  7H  8H  9H  TH  QH  JH  KH
AS  2S  3S  4S  5S  6S  7S  8S  9S  TS  QS  JS  KS
