Any idea?

Answer 1

str = "'(\\'1\\',\\'YoTWsmjxk4M5lqgmzKzF8oI6owoqJBM5mVumQ-0fL01OLS9gU63Gfw**\\',\\'\\x00\\x00\\x00\\x00\\x94\\xa7\\x2f\\x34\\',\\'\\',\\'2\\');'"

str.replace('\\', '')

use builtin replace method, which takes 2 parameters first 1 is which char you want to replace and the 2nd one is which char you want to replace with.

Answer 2

This could work in your case. If the variable is str,

str = '(\\'1\\',\\'YoTWsmjxk4M5lqgmzKzF8oI6owoqJBM5mVumQ-0fL01OLS9gU63Gfw**\\',\\'\\x00\\x00\\x00\\x00\\x94\\xa7\\x2f\\x34\\',\\'\\',\\'2\\');' 

Replace \\\\ with nothing everywhere. But then where ever 'x' is there, you lose the \\\\ preceding the x.

str.replace("\\", "");

But then as you want it before x, you put back \\\\ only before x

str.replace("x", "\\x");

Answer 3

You can use builtin replace() module of str .

string = "(\\'1\\',\\'YoTWsmjxk4M5lqgmzKzF8oI6owoqJBM5mVumQ-0fL01OLS9gU63Gfw**\\',\\'\\x00\\x00\\x00\\x00\\x94\\xa7\\x2f\\x34\\',\\'\\',\\'2\\');"

replaced = string.replace("\\'", "'")
print replaced
#Output

"('1','YoTWsmjxk4M5lqgmzKzF8oI6owoqJBM5mVumQ-0fL01OLS9gU63Gfw**','\\x00\\x00\\x00\\x00\\x94\\xa7\\x2f\\x34','','2');"
