How to print a single backslash?
You need to escape your backslash by preceding it with, yes, another backslash:
print("\\")And for versions prior to Python 3:
print "\\"The \ character is called an escape character, which interprets the character following it differently. For example, n by itself is simply a letter, but when you precede it with a backslash, it becomes \n, which is the newline character.
As you can probably guess, \ also needs to be escaped so it doesn't function like an escape character. You have to... escape the escape, essentially.
