numpy string operations | ljust() function Last Updated : 05 Feb, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report numpy.core.defchararray.ljust(arr, width, fillchar=' ') is another function for doing string operations in numpy. It returns an array with the elements of arr left-justified in a string of length width. It fills remaining space of each array element using fillchr parameter. If fillchr is not passed then it fills remaining spaces with blank space. Parameters: arr : array_like of str or unicode.Input array. width : The final width of the each string . fillchar : The character to fill in remaining space. Returns : Output array of str or unicode, depending on input type.
