Numpy string operations | rpartition() function Last Updated : 29 Aug, 2020 Comments Improve Suggest changes Like Article Like Report In the numpy.core.defchararray.rpartition() function, each element in arr, split the element as the last occurrence of sep, and return 3 strings containing the part before the separator, the separator itself, and the part after the separator. If the separator is not found, return 3 strings containing the string itself, followed by two empty strings. Syntax : numpy.core.defchararray.rpartition(arr, sep) Parameters : arr : [array_like, {str, unicode}] Given Input array. sep : [str or unicode] Right-most separator to split each element in array. Return : [ndarray] Return the output array of str or unicode, depending on input type Code #1 : Python3 # Python program explaining # numpy.char.rpartition() function # importing numpy as geek import numpy as geek arr = "GeeksforGeeks - A computer science portal for geeks" sep = 'None' gfg = geek.char.rpartition(arr, sep) print (gfg) Output : ['' '' 'GeeksforGeeks - A computer science portal for geeks'] Code #2 : Python3 # Python program explaining # numpy.char.rpartition() function # importing numpy as geek import numpy as geek arr = "GeeksforGeeks - A computer science portal for geeks" sep = 'science' gfg = geek.char.rpartition(arr, sep) print (gfg) Output : ['GeeksforGeeks - A computer ' 'science' ' portal for geeks'] Comment More infoAdvertise with us Next Article Numpy string operations | rpartition() function sanjoy_62 Follow Improve Article Tags : Python Numpy Python-numpy Python numpy-String Operation Practice Tags : python Similar Reads Numpy string operations | partition() function In the numpy.core.defchararray.partition() function, each element in arr, split the element as the first occurrence of sep, and return 3 strings containing the part before the separator, the separator itself, and the part after the separator.

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 Python String rpartition() Method String rpartition() method in Python is a powerful tool for splitting a string into three parts, based on the last occurrence of a specified separator. It provides an efficient way to handle text parsing when we want to divide strings from the rightmost delimiter. Let us start with a simple example: 4 min read String Manipulation in R String manipulation is a process of handling and analyzing strings. It involves various operations of modification and parsing of strings to use and change its data. R offers a series of in-built functions to manipulate a string. In this article, we will study different functions concerned with the 4 min read String Concatenation in R Programming String concatenation is a way of appending two or more strings into a single string whether it is character by character or using some special character end to end. There are many ways to perform string concatenation. Example: Input: str1 = 'Geeks' str2 = 'for' str3 = 'Geeks' Output: 'GeeksforGeeks 3 min read Python String rsplit() Method Python String rsplit() method returns a list of strings after breaking the given string from the right side by the specified separator. It's similar to the split() method in Python, but the difference is that rsplit() starts splitting from the end of the string rather than from the beginning. Exampl 3 min read String Matching in R Programming String matching is an important aspect of any language. It is useful in finding, replacing as well as removing string(s). In order to understand string matching in R Language, we first have to understand what related functions are available in R. In order to do so, we can either use the matching str 5 min read Get first n chars from a str column in Python Polars Polars is a powerful DataFrame library designed for speed and ease of use, particularly with large datasets. If you need to extract the first n characters from a string column in a Polars DataFrame, Polars offers efficient and straightforward methods to achieve this. In this article, we will go thro 3 min read Working with Text in R R Programming Language is used for statistical computing and is used by many data miners and statisticians for developing statistical software and data analysis.
