| | | | | Hi guys, have you ever wondered how can Python dictionaries be so fast and reliable? The answer is that they are built on top of another technology: hash tables. Knowing how Python hash tables work will give you a deeper understanding of how dictionaries work and this could be a great advantage for your Python understanding because dictionaries are almost everywhere in Python. Hash Functions Before introducing hash tables and their Python implementation you have to know what is a hash function and how it works. A hash function is a function that can map a piece of data of... | |

| | | | | Few data-structures are more ubiquitous in real-world development than the hash table. Nearly every major programming features an implementation in its standard library or built into the runtime. Yet, there is no conclusive best strategy to implement one and the major programming languages diverge widely in their implementations! I did a survey of the Hash map implementations in Go, Python, Ruby, Java, C#, C++, and Scala to compare and contrast how they were implemented. | |

While the lessons can be broadly applicable, the scope of the post is not. One of the lessons I learned during my time at AWS Cryptography (and... | ||
