Question

How to check for a new line in a string?

Does python3.x have anything similar to java’s regular operation where direct if (x=='*\n') would have worked?

Answer 1

If you just want to check if a newline (\n) is present, you can just use Python’s in operator to check if it’s in a string:

>>> "\n" in "hello\ngoodbye"
True

… or as part of an if statement:

if "\n" in foo:
    print "There's a newline in variable foo"

You don’t need to use regular expressions in this case.
