I've an array, for example: 

```
Array = [100]*100

```

Then I want to do this: 

```
Array[0:10] = 1

```

The Array should look like this: 

```
Array = [1,1,1,1,1,1,1,1,1,1,100,100....,100]

```

But Python says No and gives me 

```
Array[0:10] = 1 can only assign an iterable

```

What does it want and how can I fix it?
