The expression :

<pre><code>if num1 and num2 &lt;= 17:
</code></pre>

is like :

<pre><code>if num1 == True and num2 &lt;= 17:
</code></pre>

With <code>num1=66</code>, <code>num1</code> is similar to <code>True</code> and <code>num2 &lt;= 17</code> is evaluated

To fix your program, You need write :

<pre><code>if num1 &lt;= 17 and num2 &lt;= 17:
</code></pre>

The issue is for this line of code:

<pre><code>if num1 and num2 &lt;= 17:
</code></pre>

Python reads this as follows:

<blockquote>
 if num1 is TRUE (which it is) and num2 is less or equal to 17, then
 execute ...
</blockquote>

You were looking for

<pre><code>if num1 &lt;= 17 and num2 &lt;= 17
</code></pre>

Or even:

<pre><code>if all(i &lt;= 17 for i in [num1,num2]) 
</code></pre>

in case you want to check more than two partners eventually (i.e. you hold a list of num1, num2, num3 ...)

To write <code>num1 and num2 &lt;= 17</code> in Python, you need to be explicit:

<pre><code>if num1 &lt;= 17 and num2 &lt;= 17:
 # do something
</code></pre>

Otherwise, provided <code>num1 != 0</code>, the condition will always be <code>True</code>.

Or just use the <code>max</code> of the two values for the equivalent logic:

<pre><code>if max(num1, num2) &lt;= 17:
 # do something
</code></pre>

I'm new to python and trying to build a program that evaluates whether a potential partner is too young for someone using the / 2 + 7 rule.

despite using test variables that are well above 18 the program executes line 7 no matter what I do. I used 88/77, 77/66, 19/19, it always executes line 7.

<pre><code>num1 = float(input("What is the higher age number? "))
num2 = float(input("What is the lower age number? "))
output = num1 / 2 + 7
if num1 and num2 &lt;= 17:
 print("You're both underage")
elif num2 &lt;= 17:
 print("You're going to jail bud")
elif output &lt;= num2:
 print("That's OK")
else:
 print("They are slightly too young for you")
</code></pre>

EDIT: 

I made the fix that many suggested, but now the program is still not working as intended and I found another flaw.

<pre><code>num1 = float(input("What is the higher age number? "))
num2 = float(input("What is the lower age number? "))
output = num1 / 2 + 7
if num1 &lt;= 17 and num2 &lt;= 17:
 print("You're both underage")
elif num2 &lt;= 17:
 print("You're going to jail bud")
elif output &lt;= num2:
 print("That's OK")
else:
 print("They are slightly too young for you")
</code></pre>

when num1 = 19 and num2 = 16, the program outputs line 5 when I want it to output line 7. It's also still outputting line 7 when num1 and num2 are both set to a value higher than 17.

Python is telling me 66 <= 17
