Format output string right alignment

Question

I am processing a text file containing coordinates x  y  z       1      128  1298039 123388        0        2        every line is delimited into 3 items using  words   line split     After processing data I need to write coordinates back in another txt file so as items in each column are aligned right  as well as the input file   Every line is composed of the coordinates  line new   words 0            words 1          words 2     Is there any manipulator like std  setw   etc  in C   allowing to set the width and alignment

Try this approach using the newer str format syntax   line new       gt 12      gt 12      gt 12   format word 0   word 1   word 2     And here s how to do it using the old   syntax  useful for older versions of Python that don t support str format    line new     12s   12s   12s     word 0   word 1   word 2

You can align it like that   print     gt 8     gt 8     gt 8   format  words     where  gt  means  align to right  and 8 is the width for specific value   And here is a proof    gt  gt  gt  for line in   1  128  1298039    123388  0  2        print     gt 8     gt 8     gt 8   format  line            1      128  1298039   123388        0        2   Ps   line means the line list will be unpacked  so  format  line  works similarly to  format line 0   line 1   line 2    assuming line is a list with only three elements

Here is another way how you can format using  f-string  format   print      f   Trades    lt 15  cnt  gt 10        f  n  Wins    lt 15  wins  gt 10        f  n  Losses    lt 15  losses  gt 10        f  n  Breakeven    lt 15  evens  gt 10        f  n  Win Loss Ratio    lt 15  win r  gt 10        f  n  Mean Win    lt 15  mean w  gt 10        f  n  Mean Loss    lt 15  mean l  gt 10        f  n  Mean    lt 15  mean trd  gt 10        f  n  Std Dev    lt 15  sd  gt 10        f  n  Max Loss    lt 15  max l  gt 10        f  n  Max Win    lt 15  max w  gt 10        f  n  Sharpe Ratio    lt 15  sharpe r  gt 10        This will provide the following output   Trades               2304 Wins                 1232 Losses               1035 Breakeven              37 Win Loss Ratio       1 19 Mean Win            0 381 Mean Loss          -0 395 Mean                0 026 Std Dev              0 56 Max Loss           -3 406 Max Win              4 09 Sharpe Ratio       0 7395   What you are doing here is you are saying that the first column is 15 chars long and it s left justified and second column  values  is 10 chars long and it s right justified

I really enjoy a new literal string interpolation in Python 3 6    line new   f  word 0   gt 12    word 1   gt 12    word 2   gt 12     Reference  PEP 498 -- Literal String Interpolation
