from mindspore._checkparam import Validator # Define a function that accepts one argument, an integer. def print_positive_int(value): # Use the check_positive_int validator. Validator.check_positive_int(value, 'value') # Print the positive integer value. print(value) # Call the function with a positive integer value. print_positive_int(42) # Output: 42 # Call the function with a non-integer value. print_positive_int("not an integer") # Error: TypeError: value must be an instance of int.In this example, we define a function called `print_positive_int` that accepts one argument, `value`. Before printing the value, we use the `check_positive_int` validator to ensure that the value is a positive integer. If the value is not a positive integer, the validator raises a `TypeError` with a descriptive error message. Overall, mindspore._checkparam Validator check_positive_int is a useful tool for checking that input values are positive integers before running code that relies on those values. It saves time and reduces errors caused by invalid inputs.
