The join() function is used to add a separator character or string to any given string or to all the elements of the given array of strings. Let’s take a simple example, if you have a string “STUDY” and you want to use “–” as separator character, then using the join() function the output will beContinue Reading

The center() function is used to return a copy of the input array of the required width so that the input array of a string is centered and padded on the left and right with fillchar. Syntax of numpy.char.center(): The syntax required to use this function is as follows: The above syntax indicates that center() function takes twoContinue Reading

The multiply() function is used for repeating the string elements of an ndarray, n number of time, where n can be any integer value. For example, if we have an array with one string element “study“, using multiply() function, we can change this string to “studystudy” if we choose the multiplication factor to be 2, and to “studystudystudy” ifContinue Reading

The add() function basically returns element-wise string concatenation for two arrays. Note: If you want to concatenate two arrays then both arrays needs to be of the same shape. Syntax of add(): The syntax required to use this function is as follows: m1 The above syntax indicates that add() function takes two parameters. Parameters: Let us now takeContinue Reading

For each element in an array the splitlines() function is used to return a list of the lines in the element, breaking at line boundaries. This function calls the str.splitlines for every element in the given array. Syntax of splitlines(): The syntax required to use this function is as follows: The above syntax indicates that splitlines() functionContinue Reading

The replace() function is used to return a copy of the array of strings or the string, with all occurrences of the old substring replaced by the new substring. This function is very useful if you want to do some changes in the array elements, where you want to replace a substring withContinue Reading

The encode() function is used to encode the input string. The set of available codecs are taken from the Python standard library. This function calls the str.encode in an element-wise manner. The default encoding scheme used is utf_8. Syntax of encode(): The syntax required to use this function is as follows: The above syntax indicates that encode() is a functionContinue Reading

The decode() function in the NumPy is used to decode the input string based on the codec specified. The set of available codecs are taken from the Python standard library. This function calls the str.decode in an element-wise manner. Syntax of decode(): The syntax required to use this function is as follows: The above syntax indicates that decode() is aContinue Reading

The istitle() function returns true for each data element of the given ndarray if the elements in the input ndarray is a title cased string and there is at least one cased character. Otherwise, this function will return false. For example, Apple is title cased, but apple is not and APPLE is also not titled case. This function calls str.istitle in an element-wise manner. ThisContinue Reading
