How can I convert a character to a integer in Python, and viceversa?

Question

I want to get, given a character, its ASCII value.

For example, for the character a, I want to get 97, and vice versa.

Use chr() and ord():

>>> chr(97) 'a' >>> ord('a') 97

Such is life. I upvoted this one as well, but I doubt he still cares 11 years later.

My favorite part about this answer is that they inadvertently wrote a valid line of Python.

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')))
