Im working on a little piece of test code to test an idea for a larger script.
Here is what I've got so far:
l = []
for i in range(0,10)
l.append(i)
for i in range(0,10)
print('%s. %s' % (i, l[i])
This gives me:
0. 0
1. 1
2. 2 .... etc
which is what I expect, but what I want is to get something like
0. 1
1. 2
2. 3 .....
so that the output is clearly different on either side of the "."
I tried changing the append to l.append(i+1)
which almost worked but the output started with 1. 2 I was curious
what happend to the 0. 1 line
I know this means that I'm not understanding exactly what append actually does.
I know that my ide shows that the list as other functions like insert, etc.
Can someone explain to me whats the best way to add a value to a list
that is not long enough to accept it, without playing with the
indexes, it appears I currently am playing with them.
I know generally that we aren't supposed to care about the indexes but
this is eventually going to be part of a menuing system that displays
the index, so I do have a legit need to care about what is happening
to the list index.
