I have a string. In that string are double backslashes. I want to replace the double backslashes with single backslashes, so that unicode char codes can be parsed correctly.
(Pdb) p fetched_page '<p style="text-align:center;" align="center"><strong><span style="font-family:\'Times New Roman\', serif;font-size:115%;">Chapter 0<\\/span><\\/strong><\\/p>\n<p><span style="font-family:\'Times New Roman\', serif;font-size:115%;">Chapter 0 in \\u201cDreaming in Code\\u201d give a brief description of programming in its early years and how and why programmers are still struggling today...' Inside of this string, you can see escaped unicode character codes, such as:
\\u201c I want to turn this into:
\u201c Attempt 1:
fetched_page.replace('\\\\', '\\') but this doesn't work -- it searches for quadruple backslashes.
Attempt 2:
fetched_page.replace('\\', '\') But this results in an end of line error.
Attempt 3:
fetched_page.decode('string_escape') But this had no effect on the text. All the double backslashes remained as double backslashes.

Learn More. 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. Conversely, prefixing a special character with "\" turns it into an ordinary character.
To replace all backslashes in a string:Call the replaceAll() method, passing it a string containing two backslashes as the first parameter and the replacement string as the second. The replaceAll method will return a new string with all backslashes replaced by the provided replacement.
myString. replace("\\\\", "\\");
You can try codecs.escape_decode, this should decode the escape sequences.
