Python Help needed

I have a script that populates/updates a field based upon its content. If none of the conditions are true, I need it not to update / return <Null>. 

def Reclass(StoryHeight_Copy): 
if (StoryHeight_Copy == "1A"): 
return "1.25" 
elif (StoryHeight_Copy == "1H"): 
return "1.50" 
elif (StoryHeight_Copy == "1T"): 
return "1.75" 
elif (StoryHeight_Copy == "2A"): 
return "2.25"
elif (StoryHeight_Copy == "2H"): 
return "2.50" 
elif (StoryHeight_Copy == "2T"): 
return "2.75" 
elif (StoryHeight_Copy == "3A"): 
return "3.25"
elif (StoryHeight_Copy == "3H"): 
return "3.50" 
elif (StoryHeight_Copy == "3T"): 
return "3.75"

First, reformat your code then if add

else:
&nbsp;&nbsp;&nbsp; return None‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

The above will return <null>

otherwise, if you don't want <null>

<SPAN class="keyword token">else</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp;&nbsp;&nbsp; <SPAN class="keyword token">return</SPAN> <SPAN class="string token">"something else"</SPAN>‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

You have to return something, it is either None (aka ) or something
