Python sequence type

1. Immutable sequence types: tuple, range, str, set

001: There are several ways to construct a tuple type

1, () constructs an empty tuple.

2, a | (A,) constructs a tuple of only one element.

3, tuple (' 1 ') is constructed using the built-in tuple method.

4, (three-way) use the literal value method to construct a tuple.

002: There are not so many tricks for range, only one method of construction available in range (start index, end index, step)

003:str is not too much of a pattern; it is mainly constructed with literal values, which can be caused by single quotes, double quotes, and three quotation marks.
