numpy string operations | less() function Last Updated : 01 Jul, 2021 Comments Improve Suggest changes Like Article Like Report numpy.core.defchararray.less(arr1, arr2) is another function for doing string operations in NumPy. It checks the elements of two same shaped string arrays one by one and returns True if the elements of arr1 are less than the elements of arr2 i.e. arr1 < arr2 . Otherwise, it returns False. Parameters: arr1 : array_like of str or unicode.1st input array. arr2 : array_like of str or unicode.2nd input array.Returns : [ndarray] Output array of bools, or a single bool if arr1 and arr2 are scalars.

These functions can help to handle and manipulate string data efficiently.Table of ContentString OperationsString Information String Comparison In this article, we’ll explore the var 5 min read numpy string operations | lower() function numpy.core.defchararray.lower(arr) function is used to return an array with the elements converted to lowercase. Parameters: arr : [ array_like ] Input array which may be str or unicode. Returns : [ndarray] Output lowercased array of str or unicode, depending on input type. Code #1: Python3 # Python 1 min read numpy string operations | ljust() function 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.

It checks the elements of two same shaped string array one by one and returns True if the elements of arr1 are less than or equal to the elements of arr2 i.e. arr1 <= arr2 .Otherwise, it retur 2 min read numpy string operations | greater() function numpy.core.defchararray.greater(arr1, arr2) is another function for doing string operations in numpy. It checks the elements of two same shaped string array one by one and returns True if the elements of arr1 greater than the elements of arr2 i.e. arr1 > arr2 .Otherwise, it returns False. Paramet 2 min read numpy string operations | find() function numpy.core.defchararray.find(arr, sub, start=0, end=None) is another function for doing string operations in numpy.It returns the lowest index in the string where substring sub is found for each element in arr within the range start to end.It returns -1 otherwise. Parameters: arr : array_like of str 2 min read numpy string operations | zfill() function numpy.core.defchararray.zfill(arr, width) is another function for doing string operations in numpy. For each element in the array it returns the numeric string left-filled with zeros.The number of left filled zeros happen according to the width.
