If we assume a maximum name length of 10 characters, then we can use a combination of the width and alignment modifiers to ensure that variations in name length wont result in uneven row lengths. We set a precision of 2 and a type of fixed-point using {:.2f}. The rjust () function contains two parameters: width and fillchar. width=10 2 ' {0: < {width}}'.format('sss', width=width) 3 Further, you can make this expression briefer, by only using numbers and relying on the order of the arguments passed to format: xxxxxxxxxx 1 width=10 2 ' {0: < {1}}'.format('sss', width) 3 Or even leave out all numbers for maximal, potentially non-pythonically implicit, compactness: an upper case E as the separator character.
