\ can be used when one wants to slip a line , in a long line
for example
plot(sin(x),x,0,2, color="red",figsize=3,
\fontsize=8,frame=True)
in fact here is not really useful it's just for the example, because in
a jupyter notebook, if you write after a gomma and press "enter" the
next line will be indented

merci de m'aider à démarrer.
An attempt at translation:
Good day,
I am a very new user of sagemath. I am mastering independent operations. My
trouble is on the level of algorithms.
So far, I cannot understand how to program with sageMath (see the screenshots).
Thanks for helping me to get started.
The problem is the use of “\”. Python programs are structured by indentation,
so the way to type the program in an editor, at the command line prompt, or in
the notebook, is as follows:
def fac(n):
if n == 1:
print ‘bonjour’
else:
print “bonsai”
The OP was entering the code almost correctly, but the “\” caused the parser to
ignore the new-line, and string everything together as one line.
