The indexing of character in a string starts from ‘0’, and therefore, the string's first character always has the index equal to zero. Only numeric values will be passed inside the string to convert into float. The string to be converted must not contain any characters or symbols. Square brackets are used to access the string elements along with the index position of the string character. The ValueError: could not convert string to float occurs in Python due to the incorrect initialization of value to a string variable. In python, the string is a sequence of Unicode characters which include every character and symbol in all languages. Therefore, the characters you input in the system are converted into a binary format using the encoding techniques like Unicode and ASCII. Share this answer Posted 2-Oct-20 22:32pm. Also, triple quotes are used to display the multi-line quotes.Īs you know, that computer does not deal with characters but instead, it works only with binary numbers. ValueError: could not convert string to float: stop talking to other peoples girlfriends It is fairly obvious that the above string cannot be converted to a float value. If you do not pass any argument, then the method returns 0.0. You can use the float() function to convert any data type into a floating-point number. You can use single quotes or double quotes to display the string. Below are 6 common and simple methods used to convert a string to float in python. What are strings in python?Ī string is a series of characters inside the quotes. Before understanding the methods to convert the string to float explicitly, let us first go through the strings and float data types in python. In Python, the strings can be easily converted into the float data type if the string has only numeric values. From your busy time can someone help me in finding out the mistake i did in this code. Hence, you have to explicitly convert the string into a floating-point value so that you can perform the necessary operations on it. from numpy import asarray from sklearn.preprocessing import MinMaxScaler scaler MinMaxScaler (featurerange (0,1)) rescaledX scaler. The ValueError: could not convert string to float error occurs when we convert the string data type into the floating when the string has some characters. ValueError: could not convert string to float: female. Even though you ask for the floating-point value, the input method in python will fetch the user input as a string object. When you take a user input in python programming while working with terminal or file operations like reading or writing a file, the input is a string object.
