What Alternative can I use instead of .append in the below code

arr=[]
for i in range (1,15):
    arr.append(i*i)
    
print (arr)
#2

arr = [i*i for i in range(1,15)]

print(list(map(lambda i: i*i, range(1,15))))

The above is another method using lambda in just a single line, but it is a little bit complicated than list comprehension.
