In the case of:
print("this is \ double backslash") # case 1
print("this is \\ double backslash") # case 2
which indeed outputs:
this is \ double backslash
this is \ double backslash
The reason is because in case 1, the first is acting upon the after it and the third is escaped automatically due to the whitespace that follows, whereas in case 2, the first and third are acting upon the second and fourth respectively. Thus, both cases result in two to be printed.

Like many languages, Python allows you to use backslashes in string literals to enter special characters (like a newline) or escape otherwise untypeable characters (like quotes of the same type the string is quoted with).
Unlike in some other languages, when the following character is not one of the special characters that Python's string literals recognize (e.g. t, n, , "), it will just assume that you meant to just type a literal backslash.
Four backslashes are just two escaped backslashes. When you enter three backslashes followed by a space Python escapes your third backslash automatically, meaning it also results in printing two backslashes.
You can see the difference if your third/fourth backslash is followed by e.g. a t:
>>> print("\\t")
\t
>>> print("\t")
