Question

Accept a positive integer \(n\) as input and print the list of first \(n\) positive integers as output.

Hint

There are two ways of growing a list:

• append method
• list concatenation

L = [ ]
L.append(1)
L = L + [2]
print(L)

If you want a list of the first \(n\) positive integers, then you need to use a loop.

Solutions

Be careful to initialize L as the empty list before you begin populating it.

Solution-1

n = int(input())
L = [ ]
for x in range(1, n + 1):
    L.append(x)
print(L)

Solution-2

n = int(input())
L = [ ]
for x in range(1, n + 1):
    L = L + [x]
print(L)
