In Python, a pair of single quotes, a pair of double quotes, three single and double quotes, and the use of the difference

First of all, three single and double quotes in Python are not real annotations

>>> type ("" "abcde" "")<class'str' >>>> type ('abcd')<class' Str '>

This allows you to see three pairs of single, double quotes that have a data type

Three pairs of single, double quotes are defined when multiple lines of string can be defined

"" "" "print  (a) ABCD 

A pair of single, double quotation marks can also define a multiline string, but it's much more troublesome and troublesome.

" a\n "  "b\n " "C\n" " d\n " Print (b) ABCD

Of course, three pairs of single, double quotes can also be used to define a row of a string

So what's the use of single and double quotes? For example, to enter Let ' s me think

' Let\ ' s me think '>>> str' Let' s me think"

If single quotation marks are used, then the translator must be used

" Let ' s me think ">>> str"let' s me think"

Double quotes are not required

Similarly if the string contains double quotes such as:She said, "Hurry up".

' She said, "Hurry up". '>>> str'She said, ' Hurry up '. '

Using single quotes does not require translation

" She said, \ "Hurry Up\". ">>> str'She said," Hurry up ". '

Use double quotes to translate

In Python, a pair of single quotes, a pair of double quotes, three single and double quotes, and the use of the difference
