```h = [1, 2, 3, 2, 3, 3]

n = [, [0, 1], [0, 1, 2], , [0, 1], ]
```

I want to add each int in h to each list in n, such that I get:

```result = [, [2, 3], [3, 4, 5], , [3, 4], 3]]
```

I have failed with:

```z = []
for i in h:
for i2 in n:
k = i + i2
z.append(k)
```

I understand why this fails but I don't know the way forward

```new_n = [[int_n+h[i] for int_n in list_n] for i,list_n in enumerate(n)]
```

Among other solutions.

It's not very different from what you have tried, but uses a more compact syntax and takes advantage of enumerate() which you should use every time you loop on some list-like object

And what you tried doesn't work because when you do :

```for i2 in n:
```

i2 will be each list in n, and not each integer because n is a list of lists.

Python, Thus, converting the whole list into a list of lists. One drawback of this method is that it does not work with integer list as res.append(sub). Here we have an int array. It has 3 values in it. We create an ArrayList and add those ints as Integers in a for-loop. Add: The add() method receives an Integer. And we can pass an int to this method—the int is cast to an Integer. Cast

You can using

```z=[[z + x for z in y ]for x , y in zip(h,n)]
z
[, [2, 3], [3, 4, 5], , [3, 4], ]
```

Python lists - working with lists in Python, In the example, we create an empty list, a list from a tuple, a string, and another list. typeerror.py Message: list indices must be integers, not str. 1. Java List add() This method is used to add elements to the list. There are two methods to add elements to the list. add(E e): appends the element at the end of the list. Since List supports Generics, the type of elements that can be added is determined when the list is created. add(int index, E element): inserts the element at the given index. The elements from the given index is shifted towards right of the list.

You can use new result array

```result = []

for i in range(len(h)):
intermediate = []
for j in n[i]:
intermediate.append(j + h[i])
result.append(intermediate)
```

Python Accept List as a input From User, an input from a user. Get a list of numbers as input from the user Also Get list of strings as input from a user. Convert each list element to an integer and add it to a sum variable. Python Accept a list of lists from user input. Add 4 ints to it. var numbers = new List <int> (); numbers.

C# List Examples, Here we create 2 separate lists of ints. We add 4 prime numbers to each List. The values are stored in the order added—2, 3, 5 and then 7. Version 1: We call� From a list containing int, strings and floats, make three lists to store them separately mkohli021 From a list containing ints, strings and floats, make three lists to store them separately

ArrayList \ Language (API) \ Processing 3+, Objects can be added to an ArrayList with add() particles.add(new Particle()); number of items in the list int total = particles.size(); println("The total Note that for resizable lists of integers, floats, and Strings, you can use� Helper class for a list of ints. Lists are designed to have some of the features of ArrayLists, but to maintain the simplicity and efficiency of working with arrays. Functions like sort() and shuffle() always act on the list itself. To get a sorted copy, use list.copy().sort(). Methods

• Note that `i` is only used index `h`, so Wen-Ben's answer is more straightfoward.
