Nested tuples in python list objects use the sort method to sort them

The following article will share with you a sorting method based on sorting nested tuples in python list objects. It has a good reference value and I hope it will be helpful to everyone. Let’s take a look together

Nesting tuples in a list, when sorting, produces a copy of the original array. During the sorting process, first sort from small to large according to the first field. If the first field is the same, it will be sorted according to the second field, and so on. When letters are involved, it will be sorted in lexicographic order.

is as follows:

a = [(1, 'B'), (1, 'A'), (1, 'C'), (1, 'AC'), (2, 'B'), (2, 'A'), (1, 'ABC')] 
a 
a.sort() 
a

The output result is:

[(1, 'B'), (1, 'A'), (1, 'C'), (1, 'AC'), (2, 'B'), (2, 'A'), (1, 'ABC')] 
[(1, 'A'), (1, 'ABC'), (1, 'AC'), (1, 'B'), (1, 'C'), (2, 'A'), (2, 'B')]
