Save

A very simple module to safely save data to files in python.

When you choose a path and a name for the file you want to save your data to, the script checks if the given file at the given path already exist; if so, it adds an increasing numbering at the end of the file name (just before the file extension if there is any) untill it finds a path+name not taken already.

This prevents from losing data by inadvertently re-writing a file.

Install

$ pip install save

Basic usage

from save import save

data = 'Hey there'
save(data, 'my_file.txt')

The safe_path function

You can import the safe_path submodule to use with other libraries or functions. It provides the same functionality as save(). (Basically the save() function itself calls safe_path() to do the work)

This is an example involving matplotlib:

from matplotlib import pyplot as plt
from save import safe_path

plt.plot(range(10))
plt.savefig(safe_path('my_figure.png'))
