This is a statistical function of the NumPy library that is used to return the maximum element of an array or maximum element along an axis. To find the minimum value of an array we use the numpy.amin() function. Syntax of numpy.amax(): The syntax required to use this function is as follows: Parameters: NowContinue Reading

This is a statistical function of the NumPy library that is used to return the minimum element of an array or minimum element along an axis. Syntax of numpy.amin(): The syntax required to use this function is as follows: Parameters: Now it’s time to discuss the parameters of this method: Returned Values: This functionContinue Reading

The strip() function is used to strip or remove the leading and trailing characters for each element in an array. We can specify the character to be stripped, otherwise by default this function will remove the extra leading and trailing whitespaces from the string. This function basically calls str.strip in an element-wise manner. Syntax of numpy.char.strip(): TheContinue Reading

The swapcase() function is mainly used to return an element-wise copy of the string with the uppercase characters of the string converted to lowercase and lowercase characters converted to uppercase. In short, it swaps or changes the case of the characters in a given string. This function is locale-dependent for an 8-bitContinue Reading

The capitalize() function is basically used to convert the first character of a string to an uppercase (capital) letter. If the string is having its first character as capital already, then this function will return the original string itself. This function calls the str.capitalize in an element-wise manner. This function is locale-dependent for an 8-bit string. SyntaxContinue Reading

The upper() function is used to convert all lowercase characters of a string to uppercase. If there is no lowercase characters in the given string then this function will return the original string. Syntax of numpy.char.upper(): The syntax required to use this function is as follows: The above syntax indicates that upper() function takes two parameters.Continue Reading

The isdecimal() function returns True if there are only decimal characters in the element, otherwise, this function will return False. This function calls unicode.isdecimal for every string element of the array. It is important to note that the decimal characters include digit characters and all those characters that can be used to form decimal-radix numbers, e.g. U+0661, ARABIC-INDIC DIGIT ONE, etc.Continue Reading

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
