What is the difference between single quotes and double quotes in python

What is the difference between single quotes and double quotes in python? Let me give you a detailed introduction:

Let’s first talk about the difference between double quotes and triple quotes. The string represented by double quotes is usually written in one line.

For example:

s1 = "hello,world"

If you want to write multiple lines, then use \ ("line character"), such as:

s2 = "hello,\ 
world"

s2 is the same as s1. If you use 3 double quotes, you can write it directly, as follows:

s3 = """hello, 
world, 
hahaha."""

Then s3 is actually The above is "hello,\nworld,\nhahaha.", pay attention to "\n", so if your string has a lot of \n and you don't want to use \n in the string, then you can use 3 double characters quotation marks. Moreover, you can also add comments to the string by using 3 double quotes, as follows:

s3 = """hello,  #hoho, this is hello, 在3个双引号的字符串内可以有注释哦 
world,     #hoho, this is world 
hahaha."""

This is the difference between 3 double quotes and 1 double quote to express a string. 3 double quotes and The difference between one single quote and
is the same. In fact, there is a reason why Python supports single quotes. Let me compare the difference between one single quote and
1 double quote.
When I use single quotes to represent a string, if I want to represent the string Let's go, it must be like this: s4 = 'Let\'s go', note that there is no ' in the string, and the string It is represented by ' again, so at this time you need to use the escape character \ (\, you should know the escape character). If there are a lot of escape characters in your string, it will definitely look uncomfortable, and Python will also This problem is solved very well, as follows:

s5 = "Let's go"

At this time, we see that python knows that you use " to represent a string, so python puts the single quote ' in the string , treated as ordinary characters, is it very simple? The same is true for double quotes. Here is an example:

s6 = 'I realy like "python"!'

This is why both single quotes and double quotes can represent strings Yes.
