Difference between a list comprehension and a for loop

Question

n=input()
y=n.split()
a=([int(x) for x in y])
print(a)

output

python .\\input_into_list.py
1 2 3
[1, 2, 3]

The above

Answer 1

The main difference is in appearance and runtime speed. List comprehension is shorter, easier to understand and faster in execution time.

In your code if you want to make it same as list comprehension you need to append each element to the list:

n=input()
y=n.split()
a=[]
for x in y:
    a.append(int(x))
print(a)

this will give you the same result as list comprehension one. In addition n.split() method itself returning the input as a list of elements. So:

n=input()
y=n.split()
print(y)

this is the same as above one. Just a last comment, when you use list comprehension or another list assigning you don't need to wrap the element to the brackets like: ()

n=input()
y=n.split()
a=[int(x) for x in y]
print(a)
