# Generate all binary strings of length n [closed]

I need to generate all binary strings of length 15 and then access individual bits. Is there some function for that? Thank You

You can use words:

```
sage: W = Words(alphabet='01', length=15)
sage: W
Words of length 15 over {'0', '1'}
```

Then you can iterate over them, and access the i^th bit as follows:

```
sage: for w in W:
....: print w, w[2]
```

If you want you bits to be integers, not strings, you can do:

```
sage: W = Words(alphabet=[0,1], length=15)
sage: W
Words of length 15 over {0, 1}
```

If you want to use only Python (not sage Words), you can use the `itertools`

module:

```
sage: import itertools
sage: W = itertools.product([0,1], repeat=15)
sage: for w in W:
....: print w, w[2]
```
