What if we use double quotes instead of single?

Question

I was interpreting using python 3.5 it works fine for me any idea?

Answer 1

It just means you can use apostrophes (') without escaping them.

text1 = "I'm done"
text2 = 'I\'m done!'

O o

Answer 2

But then, you can't use double quotes inside your strings...

No performance change (vs. PHP), just aesthetics...
