Here, the ValueError has occurred inside and outside of the function for the input value, ‘d’.Įxample-5: Use of the ValueError with Other ErrorĬreate a Python file with the following script that will open a file for reading and print the content of the file. The following output will appear after executing the above script with the input values of 6, -3, and ‘d’. Print ( 'Error outside the function: ', e ) Num = input ( 'Enter a number a value: ' ) Print ( 'Error inside the function: ', e ) #Print the error message from the function #Check the number is positive or negative The try-except block will catch the ValueError passed from the function and print the error message. The function will raise the ValueError when an invalid argument value will be passed to the function. Here, the check() function has been defined to find out whether a number is positive or negative.

Here, when the function has been called with the values 5 and ‘6’, then the ValueError has been raised for the invalid value, ‘6’.Įxample-4: Use of the ValueError Inside and Outside of the FunctionĬreate a Python file with the following script that shows the uses of ValueError inside and outside the function.

The following output will appear after executing the above script. #Call the function with one number and a string Print (“Multiplication of %d and %d is %d” % (a, b, result ) )

Raise ValueError (‘The value of any or both variables is/are not a number.’ )
