Write a program whose inputs are three integers, and whose output is the smallest of the three values.
If the input is:
7 15 3The output is:
3
This is the code I have come up with:
num1 = input()
num2 = input()
num3 = input()
if (num1 < num2):
if (num1 < num3):
smallest_num = num1
elif (num2 < num1):
if (num2 < num3):
smallest_num = num2
else:
smallest_num = num3
print(smallest_num)
This code works for that input, however if you input "29, 6, 17" it returned no output with an error
NameError: name 'smallest_num' is not defined".
I have dinked around quite a bit and tried adding smallest_num = min(num1, num2, num3) however nothing has yielded a passing output.

The issue is that input() returns a string. So when you compare your variables, you're doing string comparisons instead of numerical comparisons. So, you need to convert your input to integers.
num1 = int(input("Enter num1: "))
num2 = int(input("Enter num2: "))
num3 = int(input("Enter num3: "))
print(min(num1, num2, num3))
This should work. I use C++, but it also looks like you didn't define smallest_num as a variable which could be the only problem.
if (num1 < num2 and num1 < num3):
small = num1
elif (num2 < num1 and num2 < num3):
small = num2
else:
small = num3
print(small)
