stdin is opened as `f`.

Prepare `sample1` file.
```bash

```bash
$ cat sample1 | pype -e 'print(f.read())' | python

```

```bash
$ cat sample1 | pype -e 'print(f.read().splitlines())' | python
['1', '2', '3']
```

### -n option

Execute specified python code per line.  You can access via `line` variable to each line.

```bash
$ cat sample1 | pype -ne 'print("- " + line)' | python
- 1

```

```bash
$ cat sample1 | pype -ne 'print("- " + line + "$")' | python

```bash
$ cat sample1 | pype -nle 'print("- " + line)' | python

```

```bash
$ cat sample1 | pype -nle 'print("- " + line + "$")' | python
- 1$
- 2$

```

### -m option

Import specified module before executing python code.

```bash
cat sample1 | pype -m datetime -nle 'print(f"- {line}:", (datetime.date.today() + datetime.timedelta(days=int(line))))' | python
