Go For Python Developers

Part-3: Composite Datatypes

Lists

The List is the ordered collection of multiple elements. The equivalent in Go is Slice. The main feature of Slice is it dynamic size?

Array

Negative Indexing

Python list generally has more features compared to Slice in Go. Python supports negative indexing. For Go, we have to access it as follows:

Insert

Python also has an insert function that allows us to add value to any specific position. Go doesn’t have such abstraction.

Array

Array is a fixed sized Slice. The size is defined inside the square braces.

We can make the compiler find the size from the initialized value as:

The closest thing to the fixed size we have in python is a tuple. Tuple supports indexing but doesn’t allow the change in values.

>>> a = (0, 1, 2)
>>> a[1]
1
>>> a[1] = 2

TypeError: 'tuple' object does not support item assignment
