![]() ![]() 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 into float. Solution 1: Ensure the string has a valid floating value Let’s take a look at each of the solutions. There are multiple ways to resolve the issue. ![]() There are a few other scenarios where you could get ValueError.Ĭonverting an empty string into a floating-point numberConverting a non-floating string to a floating-point number Fix ValueError: could not convert string to float If you see the above code, the order value has a comma-separated numeric value, and while parsing into a float, Python will throw ValueError: could not convert string to float. In the below code, we have the total order value in terms of USD, and we are accepting this in string format and performing a tax calculation. Let’s take a simple example to demonstrate the ValueError exception. ValueError: could not convert string to float: ‘12,000’ Print(“The total tax amount is “, tax_amount)įile “c:/Projects/Tryouts/main.py”, line 4, in Tax_amount = (float(order_value)*(tax_percentage / 100)) This means that you cannot convert a value ifĪ value contains spacesA value contains a commaA value contains special characters Exception could not convert string to float The float() method only allows you to convert strings that hold float-like numbers. This method will be useful when we need to perform a mathematical operation on a string object. Python has a built-in float() method that can parse the string to a floating-point number. If we are reading and processing the data from excel or csv, we get the numbers in the form of a string, and in the code, we need to convert from string to float.
