how to remove none from the for loop - desul - Feb-27-2017

Dear all,
c= " domain ontologies"

mystr = c.split(' ')   
   
  c= [i for i in mystr[:1]]
        
 print(c)
result 
Output:
['domain', 'ontologies']
['domain']
None

[i for i in mystr[:1] if i]
You have an interval in the begening in the string " domain ontologies". So when you split it, it returns an empty string as the first index. Which is None in Python. Use strip().

mystr = c.strip(' ').split()

As pointed out by Ofnuts in the other thread split() without argument will take care.

>>> " domain ontologies".split()
['domain', 'ontologies']

Use Code tag.
Code you have will not output what you have posted.

Just repeating what others have said: 

c = " domain ontologies"

mystr = c.split()
print(mystr[0])
print(mystr[1])
Output:
domain
ontologies
