Write a program in python whose inputs are three integers, and whose output is the smallest of the three values.

Ex: If the input is:

7
15
3

The output is:

3

To write a program in Python that finds the smallest of three values, you can use the min() function to compare the three values and determine the smallest one. Here is one possible implementation:

```python
# Get three integer inputs from the user
num1 = int(input("Enter the first integer: "))
num2 = int(input("Enter the second integer: "))
num3 = int(input("Enter the third integer: "))

# Find the smallest value using the min() function
smallest = min(num1, num2, num3)

# Print the smallest value
print("The smallest value is:", smallest)
```

By using the min() function, you can easily find the smallest value among the three given inputs.
