Question

I am trying to do a simple sub string matching in Python and although I remember last night it was working fine, but since morning this piece of code is giving the following error. It seems to be a known error, can anyone suggest why is it happening?

if string.find(row[1],drug) != -1:
    print "abstract id =  ", row[0],"Drug found=", drug

error :

File "./substring.py", line 31, in <module>
    if string.find(row[1],drug) != -1:
TypeError: slice indices must be integers or None or have an __index__ method

Here row[1] and drug both are simple strings.

Answer 1

Instead of string.find(row[1], drug), try row[1].find(drug). The .find() method will give you the index of the first occurrence of the string.
