How to get certain phrase from the middle of the string in Python

I have silly question - How can I get just the middle bunch of words? I'm missing with one value.

string = "Here is the content and I want to get middle words"
start = string.index("content")
print(string[start:i'm stucked here!!!])

Any ideas how to count this value to delete the things after content?

Not completely knowing how versatile you need this to be, or the full purpose of its use, here are a few options.

You could take the string and convert it to a list. This would give you more iteration options, depending on what your needs would be:

string = "Here is the content and I want to get middle words"
_string = string.split()
print(_string)

output = ['Here', 'is', 'the', 'content', 'and', 'I', 'want', 'to', 'get', 'middle', 'words']

If you wanted a method where you could change the word you're searching for and it would not throw an exception if the word wasn't in the phrase, here's a possibility. It may look a little verbose but again, not knowing what application you'd be using it for, the 'safety nets' it has could be helpful:

_string = "Here is the content and I want to get middle words"
word_find = "content"

def get_word_indicies(input_string, word_find):
    start_index = None
    end_index = None

    for i, x in enumerate(input_string):
        if x in word_find:
            if start_index is None:
                start_index = I
            else:
                end_index = i + 1
                if (end_index - start_index) == len(word_find):
                    return [start_index, end_index]
        else:
            start_index = None
            end_index = None
    start_index = None
    end_index = None
    return [start_index,end_index]

x, y = get_word_indicies(_string, word_find)
print(_string[x:y])

The syntax string[start:end] return the sub-sequence of string from index start to end (not included).

If you want to extract a word that start at the position start and that word is of length n, then the string[start:(start+n)] will return the word.

To get the length of a word, use len(word).

That gives you:

string = "Here is the content and I want to get middle words"
word = "content"
start = string.index(word)
end = start + len(word)
print(string[start:end])

How about this?

string = "Here is the content and I want to get middle words"
word = "content"
start = string.index(word)

print(string[start:start+len(word)])

str.search(searchItem) will return the start index of the term you are looking for and -1 if it doesn't exist.

So in your case,

string.search("content") will give you 12, which is the index of 'c' in content;

so, 

start = string.search("content") + len("content") //len to add the search term as well

//and to get substring:

string = string.substr(0,start);

For the specific use case you can use the below code

string = "Here is the content and I want to get middle words"
start = string.index("content") + len("content")
string = string [:start]
print(string)
