My favorite part about this answer is that they inadvertently wrote a valid line of Python. – ArtOfWarfare Jan 23 '16 at 22:31

Not OP's question, but given the title How can I convert a character to a integer in Python,

int(num) <==> ord(num) - ord('0')

str(char) <==> ord(char) - ord('a')

For long string you could use this.

 ''.join(map(str, map(ord, 'pantente')))
