Question

I have a string in the format: ‘nn.nnnnn’ in Python, and I’d like to convert it to an integer.

Direct conversion fails:

>>> s = '23.45678'
>>> i = int(s)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '23.45678'

I can convert it to a decimal by using:

>>> from decimal import *
>>> d = Decimal(s)
>>> print d
23.45678

I could also split on ‘.’, then subtract the decimal from zero, then add that to the whole number … yuck.

But I’d prefer to have it as an int, without unnecessary type conversions or maneuvering.

Answer 1

How about this?

>>> s = '23.45678'
>>> int(float(s))
23

Or…

>>> int(Decimal(s))
23

Or…

>>> int(s.split('.')[0])
23

I doubt it’s going to get much simpler than that, I’m afraid. Just accept it and move on.
