![]() In the below code, it will run the code in the try block. The best way is to handle the exception in case of an invalid data format. Output The total tax amount is 480.0 Solution 2: Use try-except In the below code, we are storing a valid float number as a string, and later we are converting that into floating-point to calculate tax. If the value has a comma, space, or any special characters, then it needs to be processed before converting into float. ![]() 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. 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. Converting a non-floating string to a floating-point number Fix ValueError: could not convert string to float.Converting an empty string into a floating-point number.There are a few other scenarios where you could get ValueError. 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' Output Traceback (most recent call last):įile "c:/Projects/Tryouts/main.py", line 4, in Print("The total tax amount is ", tax_amount) Tax_amount = (float(order_value)*(tax_percentage / 100)) A value contains special characters Exception could not convert string to float order_value = '12,000'.This means that you cannot convert a value if 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. ValueError: could not convert string to float In this article, we will take a look at what this error means and how to fix this error in your code with examples. Usually, this happens if the string object has an invalid floating value with spaces or comma Python will throw ValueError while parsing into string object into float. If you convert a string object into a floating-point in Python many times you will get a ValueError: could not convert string to float. Solution 1: Ensure the string has a valid floating value.Fix ValueError: could not convert string to float.Exception could not convert string to float.ValueError: could not convert string to float.Slurmstepd: error: slurm_set_addr: Unable to resolve ".
