When do you use double quotes and single quotes?

Answer 1

Though both are permitted in Python, but it's more wise to use " " , because it supports to use apostrophe ( ' ) with a word.For example -print("John\'s book") >>> John's book

Answer 2

It depends on programming language.

Answer 3

python is the language iam learning

Answer 4

So there is no difference.

/Edit
I have seen that people closing one word(string) in single quotes and text in double quotes. Example:
print 'Poland'
print "Poland is great country!"

But it is not necessary.

Answer 5
