Python - split string and return int

Question

x='2013:02:01'

y,m,d=x.split(':')

Produces y,m,d as strings. But how do I produce them as ints using only 1 line

Failed:

y,m,d=int(y.split(':'))


y,m,d=int(y),int(m),int(d)=y.split(':')

Answer 1

y, m, d = map(int, x.split(':'))

map applies the function to each of the elements in the iterable. In this case it will apply int to each of the values returned by split and give you the result.

Answer 2

Use a list comprehension:

[ int(token) for token in y.split(':') ]

Answer 3

You can use list comprehensions:

y,m,d = [int(n) for n in x.split(':')]

Answer 4

Using list comprehension will do the trick:

>>> x='2013:02:01'
>>> y,m,d=[int(n) for n in x.split(':')]
>>> y
2013
>>> d
1
>>> m
