PyPrnt helps you to print a list (sequence container) or a dictionary (mapping object) in an organized table form.  
Just try it out!  
Don't use `print()` anymore. Use `prnt()` for the rest of your life :)

## How to install

```bash
# If you have both Python 2 and 3,
pip3 install pyprnt
# If you only have Python 3,
pip install pyprnt
```

## How to use

```python
from pyprnt import prnt

creation = ["Adam", "Eve"]
menu = {
    "Kimchi": 5000,
    "Ice Cream": 100
}
print(creation)
prnt(creation) # Magic!
print(menu)
prnt(menu) # Magic!
prnt("Eat apple.") # Magic ignored for types other than list & dict
```

You should see this...

```text
['Adam', 'Eve']
┌─┬────┐
│0│Adam│
│1│Eve │
└─┴────┘
{'Kimchi': 5000, 'Ice Cream': 100}
┌─────────┬────┐
│Kimchi   │5000│
│Ice Cream│100 │
└─────────┴────┘
Eat apple.
```

Isn't this amazing? **Learn how to use this with a few more options**

## Options

> prnt(obj, enable=True, both=False, truncate=False, depth=-1, output=False, width=get_terminal_size(), sep=' ', end='\n', file=sys.stdout, flush=False)

### enable: bool (default: True)

Enable `prnt()` form.

```python
prnt(creation, enable=False)
```

```text
['Adam', 'Eve']
```

### both: bool (default: False)

Print in both original `print()` form and `prnt()` form.

```python
prnt(creation, both=True)
```

```text
['Adam', 'Eve']
┌─┬────┐
│0│Adam│
│1│Eve │
└─┴────┘
```

### truncate: bool (default: False)

Truncate output values if they exceed the maximum width of Terminal.  
The maximum width of Terminal is 50 in this example.

```python
# truncate = False
prnt(["abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz", 12345678910])
# truncate = True
prnt(["abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz", 12345678910], truncate=True)
```

```text
┌─┬──────────────────────────────────────────────┐
│0│abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrst│
│ │uvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmn│
│ │opqrstuvwxyz                                  │
│1│12345678910                                   │
└─┴──────────────────────────────────────────────┘
┌─┬──────────────────────────────────────────────┐
│0│abcdefghijklmnopqrstuvwxyzabcdefghijklmnopq...│
│1│12345678910                                   │
└─┴──────────────────────────────────────────────┘
```

### depth: int (default: -1 no limit)

Set the depth of recursive `prnt()`.  
Depth should be either -1 or bigger than 0.  
The contents beyond the depth will be printed as string.

```python
prnt(block, depth=2)
```

```text
┌─────────────┬──────────────────────────────────┐
│index        │1                                 │
│transaction  │┌─┬──────────────────────────────┐│
│             ││0│{'sender': 'Block_Reward', ...││
│             ││1│{'sender': '30819f300d06092...││
│             │└─┴──────────────────────────────┘│
│timestamp    │09/23/2019,16:08:19               │
│previous_hash│This_Is_Genesis_Block             │
│hash         │00e63fb0a8474d78df37e0ba99816d5...│
│nonce        │222                               │
└─────────────┴──────────────────────────────────┘
```

### width: int (default: current Terminal width or 50)

Set the maximum width of Terminal.  
Width should be bigger than 20.

```python
prnt(["Kevin Kim is a developer."], width=20)
```

```text
┌─┬────────────────┐
│0│Kevin Kim is a d│
│ │eveloper.       │
└─┴────────────────┘
```

### output: bool (default: False)

Get a return string for the printed content from `prnt()`.  
`prnt()` will not print anything.

```python
output_data = prnt(creation, output=True)
print(repr(output_data))
print(output_data)
```

```text
'┌─┬────┐\n│0│Adam│\n│1│Eve │\n└─┴────┘'
┌─┬────┐
│0│Adam│
│1│Eve │
└─┴────┘
```

### sep: str (default: ' ')

Default `print()` parameter.  
Put a separator between each input.

```python
prnt("010", "8282", "8282", sep="-")
```

```text
010-8282-8282
```

### end: str (default: '\n')

Default `print()` parameter.  
Put at the end of an output.

```python
prnt(creation, end="")
prnt("The force is with me")
```

```text
┌─┬────┐
│0│Adam│
│1│Eve │
└─┴────┘The force is with me
```

### file: object with a write method (default: sys.stdout)

Default `print()` parameter.

### flush: bool (default: False)

Default `print()` parameter.  
Specify if the output is flushed (True) or buffered (False).

## Caution

If the length of label part (index for list, key for dict) goes beyond the half size of your width,  
the label will be truncated to the half size of your width in order to secure enough space for displaying values.

For example,

```python
disease = {
    "pneumonoultramicroscopicsilicovolcanoconiosis": "an invented long word said to mean a lung disease caused by inhaling very fine ash and sand dust."
}
prnt(disease)
```

```text
┌────────────────────────┬───────────────────────┐
│pneumonoultramicrosco...│an invented long word s│
│                        │aid to mean a lung dise│
│                        │ase caused by inhaling │
│                        │very fine ash and sand │
│                        │dust.                  │
└────────────────────────┴───────────────────────┘
```
