if/else condition in a list comprehension

Question

I am trying to do an if/else with a list comprehension (I think). I tried to follow a normal if conditional format with the if/else at the end. I tried to add 'num for num in nums'. A few other things like the commented code at the bottom...but the best I can do is make res[] a list of 'None's. I'm sure this will never be crucial and a normal if/else in a for loop works, it's just that I read Trey Hunner's visual take on List Comps and wondered about an else.
nums = [2,53,4,7,11,1]
print(nums)
res = []
for num in nums:
if num <= 7:
res.append("less")
else:
res.append("more")
print(res)
nums = [2,53,4,7,11,1]
print(nums)
res = []
res = [res.append("less") if num <= 7
else res.append("more")
for num in nums
]
print(res)
# [a if tC else b for i in items if fC]
# [item
# for sublist in myList
# for item in (sublist if type(sublist) is list else sublist['val'])
#]

Answer 1

Yes, Thank You Jan! I don't know why I was appending. I appreciate your quick answer.

Answer 2

If you do this, the output will be correct:
nums = [2,53,4,7,11,1]
print(nums)
res = []
[res.append("less") if num <= 7 else res.append("more") for num in nums]
print(res)
# or do it this way:
nums = [2,53,4,7,11,1]
print(nums)
res = ["less" if num <= 7 else "more" for num in nums]
print(res)
# output is:
[2, 53, 4, 7, 11, 1]
['less', 'more', 'less', 'less', 'more', 'less']

Answer 4

i see Lothar. i could append inside the comprehension if i didnt assign it outside. thank you for that.
