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. This uses a width of 12, space padded, right aligned.
line_new = '{:>12} {:>12} {:>12}'.format(words[0], words[1], words[2])
Example with the interpreter:
>>> line = "123 456 789"
>>> words = line.split(' ')
>>> line_new = '{:>12} {:>12} {:>12}'.format(words[0], words[1], words[2])
>>> print(line_new)
123 456 789
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' % (words[0], words[1], words[2])
