IndexError: list index out of range - python

Question

I have the following error:

currency = row[0]
IndexError: list index out of range

Here is the code:

 crntAmnt = int(input(         


        

Answer 1

Try printing out the row. The convention for variable names in python are like_this and not likeThis. You might find the break keyword useful:

for row in exch_reader:
    currency = row[0]
    if currency == crnt_currency:
        crnt_rt = row[1]
        break

To only index the row when the row actually contains something:

currency = row and row[0]

Here row[0] is only executed if row evaluates to True, which would be when it has at least one element.
