How can i eval subindex on list[ ][ ] ?

[jairodsl]

Excuse me, i was trying in too many ways but i couldnt access subindex
on a list , the problem is the next:

I have

indif=[[0,'A'],[1,'B'],[2,'C'],[3,'D']]

and

indic=[[0,'B'],[1,'C'],[2,'D'],[3,'E']]

i need to eval if indic[j] is equal to indif[j]

I used a double for but i had got "list index out of range". How can i
do ???

Thanks a lot,

Cordially,

jDSL

py> i = 1
py> j = 0
py> indif[j] == indic[j]
True


Works for me.

Posting your actual code would help. indif[j] should be fine, if i
is between 0 and 3 inclusive, and j is 0 or 1.

Or, if you mean for every i and j, just

indif == indic

and let the types equality method do the work for you.

its working for me i think its better to mention the value of i and j
for both lists or you might have done mistake while formatting strings
it should be %s for strings and %d for numbers if any subelement in
lists does not formatted properly it may lead to error
