you insert 5 ==> a = 5 z= 2 (initially) i = 1 ( for loop starts from here) z = z*i => 2*1 => 2 as z < 5 (body ofwhile loop starts executing) z = z +1=> 2+1 = 3 # its still less than 5 # while loops doesn't end till z= 5 z = z+1 (executes again) . now as z = 5 while loop will terminate # we are back to our for loop, # range has a skip-factor of 2 # so i= 1+2 = 3 z= z*i => 5*3 => 15 # as z<5 is false while loop will not execute, not even once # again i = 3+2= 5 # but as a= 5 range only return [1,3] (not 5) hence for loop also terminates here. finally print (str(z)) => 15 Edit: go through these lessons 👇🏻 https://www.sololearn.com/learn/JUMP_LINK__&&__Python__&&__JUMP_LINK/2281/ https://www.sololearn.com/learn/Python/2435/
