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?
