[Tutor] Change a text string from a list and change it into an integer number.(WinXP/py2.6.2/Beginner)

[Shashwat Anand]

What do you want to say exactly ?
is 'cyear' an integer ?
let's say date1 = "1984_11_05"

Then of course you can change it to an integer using following
list-comprehension,
>>> date1 = "1984_11_05"
>>> date1_list = [int(i) for i in date1.split("_")]
>>> date1_list
[1984, 11, 5]
or alternatively,
>>> date1_list_alternate=map(int,date1.split("_"))
>>> date1_list_alternate
[1984, 11, 5]


also your code seems to work on my system.
