For Python language, What is the difference between single and double quotation marks

Question

While I am developing the Python code, I found I used to use single quotation marks all the time, but some experienced programmers used double quotation marks more often. I couldn't find the difference between them, could anyone help to give me some examples if there is a difference? Or is it just a personal preference? For example:

class TextBox(UIControl):
    def draw(self):
    print('TextBox')

class TextBox2(UIControl):
    def draw(self):
        print("TextBox")

class TextBox and TextBox2 seems like have no difference while running. Thanks for your help!

Instead, paste the code as text directly into your question. If you select it and click the `{}` button or Ctrl+K the code block will be indented by four spaces, which will cause it to be rendered as code. — ChrisGPT was on strike, Aug 31 '20 at 00:42
Also worth mentioning that if you have a single quote in string, like can't, using a double quote prevents you from having to escape the single quote with a back slash. — John Greenfield, Aug 31 '20 at 00:42

There is no difference between them, except for the looks. For example if you did:

print("Hello world")

It is the same as:

print('Hello world')

But I like to do the first one.

The uses of quotation marks and double quotation marks are the same, but you can use them in different cases; I'll give some examples as follows;

# Use of quotation mark ''
print('This is a "python code"')

# Use of double quotation mark ""
print("This is a 'python code'")

# More specific case (triple quotation mark)
print('''"This is a 'python code'"''')

If quotation mark is in a text to print, you should use double quotation mark. If double quotation mark is in a text to print, you should use quotation mark. If both of them is in a text to print, you should use triple quotation mark.

I'd be very happy if you let me know your opinion.
