ValueError Traceback (most recent call last) What happens if you pass a non-numeric string to the float() function? Let’s find out. If you want to convert the above string to an integer in Python, use the int() function instead. We get 150.0 as a float point number after conversion. If the String contains non-digit characters, the function will stop. If the value has a comma, space, or any special characters, then it needs to be processed before converting into float. The input String should start with a digit. What happens if you pass an integer number as a string to the float() function? Let’s find out. Solution 1: Ensure the string has a valid floating value The easiest way is to clean up the data or pass it in the correct format if we already know the data format before converting it into float. You can see that we get 150.75 as a float value. Let’s look at some examples of using the above syntax to convert a string to a floating-point value.įirst, let’s apply the float() function on a string containing a real number with a decimal part, for example, “150.75”. Note that if the passed string does not represent a numeric value, it will raise an error. It returns the passed string as a floating-point value. The following is the syntax – # convert string s to float You can use the Python built-in float() function to convert a string to a float value in Python.
