The difference between single quotes, double quotes, and three double quotes in Python

1. There is no difference between single and double quotation marks. Can be used just for convenience, reduce write too many escape characters.

Like what:

str='let\ ' s go! ' str="let' s go! "

Two kinds of equivalence, but the second is obviously more elegant.

2. Three double quotation marks are used to enter multiple lines of text, that is, the content entered between the three quotation marks will be preserved, the number and double quotation marks are not escaped, in which the invisible characters such as \ n and \ t will be preserved, the advantage is that you can replace some of the multiple lines of text.
