How To Use

Functions and classes provided by vutils-python can be accessed by importing following submodules:

• vutils.python.objects

Each of these submodules is described in the following subsections.

Objects Manipulation

Functions and classes that deals with Python objects, defined in vutils.python.objects submodule, are

• merge_data(dest, src) merges data from src to dest. src and dest must be of the same type. Examples:

  src = [1, 2, 3]
  dest = [1, 2]
  merge_data(dest, src)
  # dest will be [1, 2, 1, 2, 3]
  
  src = {1, 2, 3}
  dest = {2, 4}
  merge_data(dest, src)
  # dest will be {1, 2, 3, 4}
  
  src = {"a": "bc", 1: 2}
  dest = {1: "a", "b": "c"}
  merge_data(dest, src)
  # dest will be {1: 2, "a": "bc", "b": "c"}
  
  merge_data({}, [1])  # TypeError
  

• ensure_key(mapping, key, default) ensures mapping has a key of the same type a default. If key is not in mapping, store default to mapping under it.
• ensure_no_key(mapping, key) ensures key is not present in mapping.
• flatten(obj) flattens obj recursively if it is list or tuple.
