Detailed introduction and usage of unpack function

Below I will share with you an article using Python to export the elements of an array into variables (unpacking). It has a good reference value and I hope it will be helpful to everyone. Let’s take a look at it. Recently, I encountered a problem at work. I need to use Python to export the elements in an array (list) or tuple (tuple) to N variables. Now I will share the method I implemented with everyone. If you need it, Friends can refer to it, let’s take a look below. The problem solved requires exporting the elements in an array (list) or tuple (tuple) to N variables. Solution: Any sequence can assign its elements to the corresponding variables through simple variable assignment. The only requirement is that the number and structure of the variables need to be completely consistent with the structure in the sequence. p = (1, 2) x, y = p # x = 1 # y = 2 data = ['google'
