🔒 WHY DOES THE 2ND CODE not output '1'

[timber cairn]

n = [1, 2 ,3 ,4, 5, 6]

code 1

i = 1
while i < len(n):
print(i)
i = i + 1

code 2

j = 1
while j < len(n):
print(n[j])
j = j + 1

OUTPUT :
1
2
3
4
5
6

2
3
4
5
6

indices start at 0

[dapper estuary]

Because list indexing in python starts at 0, that means list[1] refers to the 2nd element in a list.

@placid hill@dapper estuary what is the difference between print(j) and print (n[j])

[dapper estuary]

print(j) prints the value of the variable j. That can be whatever, an integer, a string, a list ...
print(n[j]) prints the value of whatever is in the list n at position j. That can also be whatever (str, list, int, ...) but j has to be an integer (a whole number).

Thanks

!e

n = [1, 2, 3, 4, 5, 6]

print(n)
for j in range(6):
    print(f"j: {j}, n[j]: {n[j]}")```
