Loggify is a convenient way to redirect stdout and stderr to the timestamped log file. It works by temporarily overriding the default behaviour of `sys.stdout` and `sys.stderr` in the context manager. You still see the output in the console - it is just additionally streamed to the log file (see the example below).

## Installation

```bash

$ pip install loggify

```

## Usage

script.py:

```python

from loggify import Loggify

def main():

    print("START")

    for i in range(10):

        print(" " * i + "x")

    print("END")

    5 / 0   # traceback will be captured

with Loggify("main.log"):  # specify output filename

    main()

```

main.log:

```
