Question 3, Level-1

[suizhixie]

for i in range(1,n+1): NameError: name 'n' is not defined

[tiny-pangolin]

you need to initialize n to some value ex

n = 1
for i in range(1,n+1):

you should add an if check if it is user input to make sure n is positive

Hi @suizhixie, You should revisit here. And also check to Python 3.x solutions, more question will be added soon.

[amit-gadia]

defined n because you add value in n

[skvishnoipro]

You have to be define it. It means that you have to tell your machine that from where n starts.

[shyamgupta196]

it will give an error since you havent declared n you can do something like n='any_thing' for i in range(1,len(n)+1): print(i) 1 2 3 4 5 6 7 8 9 should help
