DotIndex

Allows you to use dot notation to index dicts, like how you can in javascript

When printed, DotIndex objects are printed as a normal dict would be, however the curly braces have a full stop before them, to signify that it is a DotIndex object. (.{} would be an empty object)

Code Examples

Basic usage:

from DotIndex import DotIndex

x = {
  "foo": "bar"
}

y = DotIndex(x)

print(y) # Expected output: ".{'foo': 'bar'}"
print(y.foo) # Expected output: "bar"
print(y["foo"]) # Expected output: "bar"

y["cat"] = "dog"

print(y.cat) # Expected output: "dog"

Adding together objects:

from DotIndex import DotIndex

x = DotIndex({
  "foo": "bar"
})

y = DotIndex({
  "cat": "dog"
})

# Adds all values in y to x
# Also works if you do `x = x + y`
x += y

print(x) # Expected output: ".{'cat': 'dog', 'foo': 'bar'}"

# Adding a DotIndex and a dict
z = x + {
  "dicts": True
}

print(z) # Expected output: ".{'cat': 'dog', 'dicts': True, 'foo': 'bar'}"

# The second value overwrites any duplicate keys from the original object
z += {
  "cat": "not dog"
}

print(z) # Expected output: ".{'cat': 'not dog', 'dicts': True, 'foo': 'bar'}"

Documentation

Creating the object

• Parameters
  • obj (dict[str, Any]) - the dict object that should be turned into a DotIndex object
  • recursive (bool, default: True) - whether or not to DotIndex-ify any dicts inside the original object
  • verbose_logs (bool, default: False) - whether or not to print out extra logs
  • ignore_errors (bool, default: False) - whether or not to ignore non-critical errors
• Other information:
  • Keys in obj must be strings, any other types will throw a TypeError (ignored with ignore_errors)
  • Keys in obj cannot start with two underscores ("__") as those could be used to overwrite preexisting instance variables used for the class itself
  • If recursive is true, the values of verbose_logs and ignore_errors will be passed through into any new DotIndex objects created

Converting types

• iter(...) - Returns all keys in alphabetical order
• str(...) - Returns a string formatted like the str(...) value of a dict object, with a full stop (".") at the start to show that it is a DotIndex type. Example: ".{'foo': 'bar'}"
• repr(...) - Same as str(...)
• int(...) - Returns the amount of keys in the object
• float(...) - Same as int(...) except as a float type
• bool(...) - Returns True if there are any keys in the object, and if there aren't it returns False

Comparisons

• == - Checks if the two objects have all the values the same. Works with both DotIndex objects and dict objects
• != - Opposite of ==
• >, <, >=, <= - Compares the amount of keys in the object

Misc.

• + - Takes the keys from the object on the right and adds them to the object on the left, overwriting any duplicates
• len(...) - Returns the amount of keys in the object
• 'val' in ... - Returns true if "val" is a key in the object
