What does dict mean in python?
The dict() function in python is used to create a dictionary. Dictionaries are another mutable container model and can store any type of object. Each key=>value pair in the dictionary is separated by colon :, each key-value pair is separated by comma,, and the entire dictionary is included in curly braces {}.

What is the principle of Dict implementation in Python?
1. Implementation of unordered Dict Dict is very fast when searching for keys, thanks to its space-for-time idea and hash implementation. When reading and writing the Key, the Key will be hashed (so the Key is required to be an immutable type. If it is a variable type, its hash value cannot be calculated), and then based on the calculated value , perform modulo calculation with the current array space length, and the obtained value is the subscript of the current Key in the array. Finally, through the subscript, the value can be read with a time complexity of O(1). This implementation is great, and it is A common distributed approach, but there are also problems. What should I do if the array is full or have different keys, but the hash results are the same? The solution to the first problem is
