“'int' object is not iterable”without int


“'int' object is not iterable”without int

this one helps. Your issue here is that result is not always a list, in your first instance you have result = [i,item] but in the else: you have it returned as an integer which is not an iterable object in python. Change your code to this and it should work:
code :
class Solution:
    def twoSum(self,nums,target):
        count=0
        i=0
        j=0
        item=0
        result=[]
        self.n=nums
        self.t=target
        count=len(self.n)
        for i in range(0,count):
            for item in range(0,count):
                print(i)
                print(item)
                j=self.n[i]+self.n[item]
                if j==self.t:
                    result=[i,item]
                else:
                    result=[0]
                    return result            
a = [3,2,4]
b = 6
c=Solution()
print(type(c.twoSum(a,b)))
print (list(c.twoSum(a,b)))

Is casting from Iterable<?> to Iterable<Object> always safe?

Is casting from Iterable<?> to Iterable<Object> always safe?

Hope that helps Is casting from Iterable to Iterable always safe? , Now I know what bothered me:
code :
Integer blown() {
    List<Integer> intList = new ArrayList<Integer>();
    Iterable<?> iterable = intList;

    @SuppressWarnings("unchecked") // This cast should be safe, shouldn't it?
    Iterable<Object> objectIterable = (Iterable<Object>) iterable;
    safeMethod(objectIterable);

    return intList.get(0);
}

// This method is definitely fine, no unchecked cast.
private void safeMethod(Iterable<Object> objectIterable) {
    if (objectIterable instanceof List) {
        List<Object> list = (List<Object>) objectIterable;
        list.add("blown!");
    }
}

it should still fix some issue my route.js , Your backend returns an object, not an array:
code :
res.json({universities: resultArray}); // => {universities: [{...}, {...}]}
this.http.get('http://localhost:3000/api/usa').map(res => res.json().universities) // Might need a null check here

it should still fix some issue The typing.Iterable is generic, so you can say what it's an iterable of in your type annotations, e.g. Iterable[int] for an iterable of ints.
The collections iterable is an abstract base class. These can include extra mixin methods to make the interface easier to implement when you create your own subclasses.
Python parallel append to proxy list return 'function' object is not iterable or 'NoneType' object is not iterable

hop of those help? I want to append list Python parallel processing. I write code as follow: , It seems to be a solution:
code :
import multiprocessing
inputs = enumerate(my_list)
manager = multiprocessing.Manager()
lproxy = manager.list()
from joblib import Parallel, delayed
def process(word) :
    lproxy.append(word)
results = Parallel(n_jobs=num_cores)(delayed(process)(word) for idx, word in inputs)
l = lproxy[:]
Object not iterable in python when created made class iterable for objects

Object not iterable in python when created made class iterable for objects

it helps some times I am making a program where I need to iterate through every option in a class to perform actions to each object, to do that I made an 'IterRegistry' Class to turn the metaclass of my objects to iterable but for some reason, it still isn't working. , Declaring a class metaclass like this:
code :
class TreeLine(object):
    __metaclass__ = IterRegistry
class TreeLine(metaclass=IterRegistry):
    ...
>>> class M(type):pass
... 
>>> class C:
...     __metaclass__ = M
... 
>>> type(C)
<class 'type'>
>>> class D(metaclass=M):pass
... 
>>> type(D)
<class '__main__.M'>
>>>
