The isdigit() function returns True if all the characters in the element are digits or numbers otherwise, this function returns False. Syntax of numpy.char.isdigit(): The syntax required to use this function is as follows: The above syntax indicates that isdigit() function takes a single parameter. In the above syntax, the argument arr is mainly used to indicate the input arrayContinue Reading
The isspace() function of the NumPy library returns True if all the characters in the element are whitespaces, otherwise, this function will return False. Syntax of the isspace(): The syntax required to use this function is as follows: The above syntax indicates that isspace() function takes a single parameter. In the above syntax, the argument arr is mainly used toContinue Reading
The startswith() function returns a boolean array with values that can either be True or False. This function will return True, if the given string starts with the specified prefix value in the function. Hence the function stands true to its name. This function calls str.startswith ifor all the string elements of the array, if it is used with anContinue Reading
The index() function is used to perform string search operation in a given array of strings. If we have an array of strings then this function will provide the first index of any substring to be searched, if it is present in the array elements. Syntax of index(): The syntax required to useContinue Reading
The isalpha() function returns True if all the characters in the string element are alphabets, otherwise, this function will return False. This function calls str.isalpha internally for each element of the array. This function is locale-dependent for an 8-bit string. Syntax of isalpha(): The syntax required to use this function is as follows: The above syntax indicates that isalpha() function takesContinue Reading
The isupper() function returns True for each string element of the ndarray, if all the characters of the string element are in uppercase. Otherwise, this function will return False. For empty strings and for special characters too, it will return False. This function calls str.isupper internally for each element of the array. This function is locale-dependent for an 8-bitContinue Reading
The lower() function is used to convert all uppercase characters into lowercase characters. If there is no uppercase characters in a given string then this method will return the original string itself. This function calls str.lower internally for every element of any given array. This function is locale-dependent for an 8-bit string. Syntax of numpy.char.lower(): The syntaxContinue Reading
The title() function is used to convert an input string into a title cased version. Syntax of numpy.char.title(): The syntax required to use this function is as follows: The above syntax indicates that title() function takes two parameters. In the above syntax, the argument arr indicates the input array of strings on which this method will be applied.Continue Reading
The split() function is used to return a list of strings after breaking the input string by the specified separator(sep). This function usually calls str.split internally on every element of the array. Syntax of numpy.char.split(): The syntax required to use this function is as follows: The above syntax indicates that split() function takes two parameters. Parameters: LetContinue Reading
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
