Print("\nThe sum is: ", sum_values) Enter the first value: 4 Value_2 = input("Enter the second value: ") value_1 = input("Enter the first value: ") Let’s take the example of a program that takes an input and performs a calculation on the input. If we pass an argument to int() that contains letters or special characters, we will raise the invalid literal ValueError.Īn integer is a whole number, so the argument provided should only have real numbers. The value of 5 is appropriate for the float function.įor further reading of ValueError, go to the article: How to Solve Python ValueError: cannot convert float nan to integer. The code does not throw an error because the float function can convert a numerical string. You can only convert numerical strings using the float() method, for example: value = '5' The above code throws the ValueError because the value ‘ string‘ is an inappropriate (non-convertible) string. ![]() ValueError: could not convert string to float: 'string' ValueError Traceback (most recent call last) ![]() Let’s look at an example of converting several a ValueError: value = 'string' You will encounter a ValueError in Python when you use a built-in operation or function that receives an argument that has the right type but an inappropriate value. In Python, a value is the information stored within a certain object.
