从值中拆分整数和字符串

Question

I have a list which include both integers and strings in every value. I want to make a list of values with only integers. ie.;

list = [u'1.0.365-SNAPSHOT', u'1.0.366-SNAPSHOT', u'1.0.367-SNAPSHOT', u'1.0.368-SNAPSHOT', u'1.0.369-SNAPSHOT', u'1.0.370-SNAPSHOT', u'1.0.372-SNAPSHOT', u'1.0.373-SNAPSHOT']

I would like to have list of values which should look like

list = [u'1.0.365', u'1.0.366', u'1.0.367', u'1.0.368', u'1.0.369', u'1.0.370', u'1.0.372', u'1.0.373']

I have been trying to use various functions such as spilt() . But was unable to get the desired result.

Answer 1

This should do the trick:

for file_name in list:
   file_name = file_name.split('-')[0]

Answer 2

Assuming all values in the list end with "-SNAPSHOT" :

lst = [u'1.0.365-SNAPSHOT', u'1.0.366-SNAPSHOT', u'1.0.367-SNAPSHOT', u'1.0.368-SNAPSHOT', u'1.0.369-SNAPSHOT', u'1.0.370-SNAPSHOT', u'1.0.372-SNAPSHOT', u'1.0.373-SNAPSHOT']
lst2 = [x[:-9] for x in lst]

Try to avoid naming lists list . It will override the built-in type.
