Answer
In the above code, Python would raise an error because round brackets are used in list comprehension. List comprehensions work with square brackets only.
Explanation
The corrected code is:
gen = [i/2 for i in [0, 9, 21, 32]]
print(gen)
The equivalent for loop for the above list comprehension is:
gen = []
for i in [0, 9, 21, 32]:
gen.append(i/2)
print(gen)
