Single-and-double cited problems in the Python sequence-unsolved, python Single-and-double cited problems

When I learned the basics of python, I encountered the following problem:

Tuple = (2, 2.3, "yeah", 5.6, False)
List = [True, 5, "smile"]

The input result is as follows:

(2, 2.3, 'yeah', 5.6, False) [True, 5, 'smile ']

I don't understand why the output is a single lead, so I tried the following:

Tuple = (2, 2.3, 'yeah', 5.6, False) list = [True, 5, "'smile '"]
Print (tuple, list)

Output result:

(2, 2.3, 'yeah', 5.6, False) [True, 5, "'smile '"]

I still don't understand the rule:

Tuple = (2, 2.3, 'Yeah "', 5.6, False) list = [True, 5, 'smile']

Output result:

(2, 2.3, 'Yeah "', 5.6, False) [True, 5, 'smile']

It seems that a single cited string must be paired, and the dual cited string can be unpaired. The dual cited string can also be a member of the string.
