Iam writing a code that I need to print \ character. I searched a lot and I saw this solution that to put "\\" in a string but the problem is that when printing it will print \\ not \ and the same for | character. Anyone know what to do?

I've tried and searched a lot but I didn't find how to print \ not \\ or .

\ in a string starts an escape sequence which allows using special characters. To use a plain backslash, you need to escape it; in other words, double it up: "\\". This works. When you print the string, it prints a single backslash:

>>> print("\\")
\

You probably tried printing it by entering the value directly on the Python terminal without calling the print function. This will show you a representation of the Python value, including quotes and, yes, escape sequences:

>>> "\\"
"\\"

Note the quotation marks!

An alternative to the above in Python is to use raw string literals. This works everywhere except just before a quotation mark:

>>> print(r"\x")
\x
>>> print("r\")
Syntax error

By contrast, the pipe character (|) is not special. If you want to use it, just put it directly into the string:

>>> print("|")
|

print("\\")

as here

Try it.
