print(list[Index_Number_For_Bannas])

find index of sublist in list python

greeting = ['hello','my','name','is','bob','how','are','you','my','name','is']

def find_sub_list(sl,l):
    results=[]
    sll=len(sl)
    for ind in (i for i,e in enumerate(l) if e==sl[0]):
        if l[ind:ind+sll]==sl:
            results.append((ind,ind+sll-1))

    return results

print find_sub_list(['my','name','is'], greeting) 
# [(1, 3), (8, 10)]

get specific index in a list

//this is a fairly crude method but worked for me when iterator
//method didn't work. 

template <class T>
T getItemAtIndex(std::list<T> list, int n) {
	int _pos = 0;
	for (T i : list) {
		if (_pos == n) {
			return i;
		}
		_pos++;
	}
}

get index of item in list

list.index(element, start, end)
