The definition of an array in Python, go.

This is a created article in which the information may have evolved or changed.

What is an array? Arrays are defined at the beginning of the length, generally not defined length is not called an array, because the array in memory is a contiguous memory, if not defined length, it is likely to change the memory address of the array.

Thus, the array in Go is strictly an array, while the list, set, tuple, dictionary are all not in Python, while the go language is slice corresponds to the half list of Python, because the list in Python, Can be various types of composition, such as a=[1, "F", 12254,[1,2], this is a flexible, somewhat like Java generics.

The go language lacks generics and can only define data of the same type, such as

A: = []int{1, 2, 3, 4}

Note that this is slice, because there is no length defined. And the go language, such as the definition of arrays:

B: = [4]int{1, 2, 3, 4}

Above A, B is not equivalent, popular is the array and slice different, according to the language type of the two is []int, the other is [4]int, the two certainly not the same.
