List index out of range, but list has enough elements

[Costin GamenÈ›]

Hi, I am trying to read a string as csv, but I encountered an odd
problem. Here's my code:

csvfile = csv.reader(datastr.split('\n'), delimiter=';')
r = ''
for i in csvfile:
for j in i:
print j
print i[0]

the "print j" statement works, but "print i[0]" returns "IndexError:
list index out of range". Am I missing something?

Change

print i[0]

to

print i

You'll see that there are empty rows in your data. You cannot detect these
rows with

for j in i:
print j

because you get zero iterations, i. e. the

print j

statement is never executed for these rows.
