How would I check a string for a certain letter in Python?

Question

Look at the following code. 

How might I advise Python to check the beneath for the letter x and afterward print "Yes"? The beneath is the thing that I have up until now...

dog = "xdasds"

 if "x" is in dog:

      print "Yes!"

Answer 1

We can use in keyword

if "x" in dog:

    print "Yes!"

Even if you want to check the character which is not existing in the string, you can use not in:

if "x" not in dog:

    print "No!"
