Print raw string from variable? (not getting the answers)

Question

Answer 1

I have my variable assigned to big complex pattern string for using with re module and it is concatenated with few other strings and in the end I want to print it then copy and check on regex101.com. But when I print it in the interactive mode I get double slash - '\\w' as @Jimmynoarms said:

The Solution for python 3x:

print(r'%s' % your_variable_pattern_str)
