10.7. Glossary¶
- Dictionary¶
A mapping from a set of keys to their corresponding values.
- Hashtable¶
The algorithm used to implement Python dictionaries.
- Hash function¶
A function used by a hashtable to compute the location for a key.
- Histogram¶
A set of counters.
- Implementation¶
A way of performing a computation.
- Dictionary Item¶
Another name for a key-value pair.
- Key¶
An object that appears in a dictionary as the first part of a key-value pair.
- Key-value pair¶
The representation of the mapping from a key to a value.
- Lookup¶
A dictionary operation that takes a key and finds the corresponding value.
- Nested loops¶
When there are one or more loops “inside” of another loop. The inner loop runs to completion each time the outer loop runs once.
- Dictionary Value¶
An object that appears in a dictionary as the second part of a key-value pair. This is more specific than our previous use of the word “value”.
