What is a double quote

Question

I don't understand what the difference between a single quote and a double quote

Answer 1

Single quote - '
Double quote - "
In Py it doesn't really matter which one do you use, but in other languages using the wrong quotes could cause an error.

Answer 2

You can use single or double inverted comma's to create string .but if you want to do tricks with your String then you can try both.
e.g=
x=('"Hi"')
print(x) output="Hi" because "" is also a string here.
