The following code utilizes exception handling on the original code given above to convert a string to decimal in Python. The finally block contains the statements that need to be executed and is ignored by the try and except blocks.The except block is used to add exceptions and handle the errors of the code.The try block contains the cluster of code to be tested for any errors.The try.except statement is divided into three blocks all three of the blocks have a different purpose. The try.except statement is utilized for the purpose of exception handling in Python. We can take a quick detour from the original code and use exception handling in this code to avoid this. ValueError: could not convert string to float: '1,5.54' The above code provides the following output: Traceback (most recent call last): The following example code will help you understand it better. When a comma separates the numbers in the string and the float() function is directly called on the string, then it gives a ValueError. Use Exception Handling Convert a String Containing a Comma to a String in Python The above code provides the following output: 5.54 The following code uses the float() function to convert a string to decimal in Python. Here, we will enter a string and perform the float() function on the given string.
