What is %% for in Python?
Question:
I’m trying to understand the following Python quine:
s = 's = %rnprint(s%%s)'
print(s%s)
In particular, I’m having trouble finding any info about that %% part.
Anyone know what that does exactly, in this context?
Postscript: Sorry for the silly question – it’s just an escape character.
My google search was focused on %%, which didn’t lead me in the right direction. Thanks to those who took the time to respond! 🙂
Answers:
%% means a percent symbol after using the % operator on your string.
% is a special symbol for substitutions, so when you put
'Hi %s'%name
you are substituting a variable into the string at the point where %s occurs.
There are lots of other % codes for different uses.
But to just get a percent symbol after substitution, you put %%.
