This article is about how python unpacks sequences. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Sequence unpacking

We define a variable and store the first and last names of the first names. If we want to extract their first and last names separately and store them in different variables, our easiest way is to use the split () function:

Name = "Xiao Chen" str_list = name.split () first_name = str_list [0] last_name = str_list [1]

In fact, this code can be rewritten as:

Name = "Xiao Chen" first_name,last_name = name.split ()

We directly assign the elements in the list returned by the split () function to first_name and last_name. This operation is called sequence unpacking in python, where the sequence is not necessarily a list, it can be a tuple, or even a range.
