How can I print a single backslash?
(4 answers)
Closed 7 months ago.
I want to add a backslash to a list in Python but it gives an error.
Output:
chars = [".", ",", "/", "\"]
^
SyntaxError: unterminated string literal (detected at line 8)
Backslashes allow you to enter characters that are normally used by the code, eg. " and '. To avoid the problem, simply just add another back slash. "\" -> "\\"
It is giving an error because \ is an escape character, You can store this using escaping this another escape character
chars = [".", ",", "/", "\\"]

When trying to make this replacement:
'C:\\Users\\uXXXXXX\\Downloads\\Folder\\Unprocessed\\FINAL_OUTBOUND.txt'.replace(r'\\', r'\')
Python throws the below error
File "<ipython-input-138-36d102855db9>", line 5
'C:\\Users\\uXXXXXX\\Downloads\\Folder\\Unprocessed\\FINAL_OUTBOUND.txt'.replace(r'\\', r'\')
^
SyntaxError: EOL while scanning string literal
How can I make this replacement successfully?
What are you trying to replace? the double slash is because by default a backslash is an escape character, if you want it as a literal then you do a double backslash to escape it.
you can see when you print it, it doesnt print with double backslashes. if you dont want to put double backslash in the string then you can tell python to read it as a raw string and not consider any special meaning in chars. you do this by prefixing the string with an r
text = 'C:\\Users\\uXXXXXX\\Downloads\\Folder\\Unprocessed\\FINAL_OUTBOUND.txt'
print(text)
text = r'C:\Users\uXXXXXX\Downloads\Folder\Unprocessed\FINAL_OUTBOUND.txt'
print(text)
OUTPUT
C:\Users\uXXXXXX\Downloads\Folder\Unprocessed\FINAL_OUTBOUND.txt
C:\Users\uXXXXXX\Downloads\Folder\Unprocessed\FINAL_OUTBOUND.txt

In Python 3 I am trying to make a set containing a backslash as an element:
a = {"/", "\"}
But I noticed that as soon as I closed the bracket after "\", the bracket became blue. I, learned that \ is an "escape" character used in things like \r, \t etc. But I want to take a backslash as a single piece of string. How to prevent this problem?
You need to escape the \ by also using a backslash.
Therefore you will need two \\
Your string will then become a={"/","\\"}
In Python strings, the backslash "" is a special character, also called the "escape" character. It is used in representing certain whitespace characters: "\t" is a tab, "\n" is a newline, and "\r" is a carriage return.
you can use this for \ and /:
>>> print('apple\torange')
apple orange
>>> print('apple\norange')
apple
orange
>>> print('\\')
\
>>> print('/')
/

python replace backslashes to slashes

I need to replace a python string that contains a number of '\':
String = 'A\BBC\CCB\:ABC'
goal = 'A/BBC/CCB/:ABC'
num = String.count('\')
String.replace('\','/')
But I keep getting error message:
SyntaxError: EOL while scanning string literal
The \ character in python has special uses. Eg. "\n" (newLine Character). In order to replace it in a string, you need to use one of the following:
String.replace('\\','/')
String.replace(r'\','/')
The "\" will look for the "\" character.
The r'\' will look for the raw interpretation of the string '\'
In your case you can do it like this:
string.replace('\\', '/', num)
Use '\', consider this situation:
print( "He said: \"Something about her.\"" );

How can I put an actual backslash in a string literal (not use it for an escape sequence)?

When I try to use
print variable + "\filename"
the slash isn't recognized as a string character,
however if I were to do
print variable + "\Filename"
capitalizing the first letter proceeding the slash... then the slash is recognized as a string character
The only thing I was able to find online is that in some cases a \ with a letter preceding it may be used to end a string of raw characters but I don't understand this.
So my question is why does this happen? And more importantly what is a way around this or a fix for this. Thank you.
You need to mark it as raw with the prefix r. Like this: print variable + r"\filename" Or alternatively you can escape it using a backslash print variable + "\\filename"

How can I compare if a backslash is in my string?
I don't know how to write the backslash symbol to compare it.
I try this but don't work:
Code:
s = r"\""
print s
Output: \"
If I try s = "\"" it gives " as output
I don't know how to acheive that.
Thanks for any help.
You need to escape the backslash.
s = "\\"
>>>mystring = "can python find this backslash \n"
>>>"\\" in r"%r" % mystring
True
while trying to filter the backslash \ character from being used in Windows filenames I searched a lot of places for answers. this is the solution worked for me.
based on information I read at...

Backslashes are used for escaping, so to display a backslash in a string literal you need to escape the backslash with another backslash.
print "\\"
prints a string with 1 backslash.
"\\" in mystring
Where mystring is your string. Will tell you if it contains a backslash
