ValueError: could not convert string to float: 'cat'Īs expected, we get an error because the passed string cannot be represented as a floating-point number. ValueError Traceback (most recent call last) Convert the string to a float using float (element) and append it to the new float list using the list.append () method.

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. What happens if you pass an integer number as a string to the float() function? Let’s find out. 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”. Depending on the scenario, you may use either of the following two approaches in order to convert strings to floats in Pandas DataFrame: (1) astype (float) df 'DataFrame Column' df 'DataFrame Column'.astype (float) (2) tonumeric df 'DataFrame Column' pd. 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. How to convert string to float in Python?
