My understanding was that Python strings are immutable.
I tried the following code:
a = "Dog" b = "eats" c = "treats" print a, b, c # Dog eats treats print a + " " + b + " " + c # Dog eats treats print a # Dog a = a + " " + b + " " + c print a # Dog eats treats # !!!
Shouldn’t Python have prevented the assignment? I am probably missing something.
Now we will see solution for issue: Aren’t Python strings immutable? Then why does a + ” ” + b work?
a pointed to the string “Dog”. Then you changed the variable
a to point at a new string “Dog eats treats”. You didn’t actually mutate the string “Dog”. Strings are immutable, variables can point at whatever they want.
