calculating length of string - desul - Feb-27-2017
Dear All,
how can I calculate the length of the string, for e.g
len(ontology)= 8
but I need it should return 1..... PLEASE TELL ME ANY COMMAND FOR IT IN PYTHON.....
THANK YOU IN ADVANCES
RE: calculating length of string - micseydel - Feb-27-2017
Are you saying you want the length of the string "ontology" to be one? Could you elaborate a bit on your question?
RE: calculating length of string - desul - Feb-27-2017
actually, I want to calculate a length of term
for e.g [information exchange]
len([information exchanhe])= 19
but I want it to return 2 instead 19 bcz two terms
len([ontology ])= 9
but i want it to return 1 bcz single term
RE: calculating length of string - micseydel - Feb-27-2017
A simple solution to this would be to split on spaces and get the length of that.
What's the context for this? A homework assignment? Or some other project?
In either case, if you write code giving it a try we're more likely to help along toward fully completing the code.

domain = "statistical"
split_domain = domain.split(" ")
for part in split_domain:
print(len(part))
returns 11 but i want 1
11

Do it this way:
domain = "statistical"
split_domain = domain.split(" ")
print(len(split_domain))

Please, use python code tags, when posting code. This helps preserve the indentation.
What you describe as desired result is number of words in the string, not length of the string itself. words being defined as one or more constitutive non-blank chars. what micseydel suggest is the most simple approach.
>>> mystr = 'statistical'
>>> len(mystr.split(' '))
1
>>> mystr = 'some string'
>>> len(mystr.split(' '))
2
>>> mystr = 'yet another string'
>>> len(mystr.split(' '))
3however you need to take into account multiple spaces, new line, etc.>>> mystr = 'some string'
>>> len(mystr.split(' '))
4
>>> print mystr.split(' ')
['some', '', '', 'string']

split() without arguments will do just that:
Output:>>> x='abcd efgh\tijkl\n mnopq'
>>> print x
abcd efgh ijkl
mnopq
>>> x.split()
['abcd', 'efgh', 'ijkl', 'mnopq']RE: calculating length of string - nilamo - Mar-22-2017
Regular expressions are cool sometimes, too:
>>> import re
>>> regex = re.compile(r"\s+")
>>> regex.split("hello there\tevery body!")
['hello', 'there', 'every', 'body!']
