Exam 98-381 topic 1 question 9 discussion

the ans should be totalItems = int(float(input("How many items would you like?")))

answer should be D

IF you handle decimals, when input, you must use float. Later you can change this as int

Whole number means all positive numbers including 0. Doesn't include fractions, decimals or negatives numbers.

B. totalItems = float(input("How many items would you like?")) The number will be used in a calculation at a later stage, meaning we will convert it later. Selecting D will give us an error when we enter an integer as a parameter.

Lets look at: "The value must be used as a whole number in a calculation, even if the user enters a decimal value." "...even if the user enters a decimal value." - This indicates that we have to allow the user to enter a float or integer. "..must be used as a whole number in a calculation.." - This does not state that we have to immediately convert the value to an integer. Therefore, the two implementations below should be correct: 1. totalItems = int(float(input("How many items would you like?"))) 2. totalItems = float(input("How many items would you like?")) totalItems = int(totalItems) # We convert to int later in our program. Thus, the nearest correct answer will be B. Option D will fail when we enter a decimal value is entered by the user, which makes our program non-compliant to the requirement that we have to allow integers and float values.

Wait, I'm pretty sure the answer is supposed to be D

Answer should be Option D

x=int(input("please enter the number float:")) please enter the number float:13.56 Traceback (most recent call last): File "<pyshell#0>", line 1, in <module> x=int(input("please enter the number float:")) ValueError: invalid literal for int() with base 10: '13.56' x=float(input("please enter the number float:")) please enter the number float:25.556 >>> print(int(x)) 25 So D is correct option as that code snipped will be used in the function first , to convert string into float .

In this the right answers is D because we have to print a whole number and in whole number never a decimal and fraction occur so no float() will be used

The answer B is correct.

should this code have error handling? except statement?

the answer should be D

this is a bad question. is had to be "B" "D" will throw an error. totalItems = float(input("How many items would you like?")) totalItems = int(totalItems)

Vaibhavdhingra24 is correct. When trying to convert int(input("enter number")) when a float is entered by user does indeed throw a ValueError. This question is worded wrong when stated the value needs to used as a whole number.

doesn't float handle integers that are calculated when entered as a string?
