why does it print "ooh" ```python for letter in "You got this!": if letter in "oh": print(letter) ```

why does it print "ooh"

for letter in "You got this!":
    if letter in "oh":
        print(letter)

Can someone explain to me how I should be reading this code? Line by line please.

they could have picked letters that didn't form a word. I would even expect there to be a comma between o and h in the IF line, but that's probably not how it works

The first and last statements are self-explanatory. Without the "if" in between, the program would just print out every letter in the string, one at a time.

But the "if" causes it to print only letters "h" and "o".

So what you see is the "o" from "You", followed by the "o" from "got", and finally the "h" from "this".

Thank you, Steven, That was what I thought, but I was not sure.

How is there two O's when there is only one in "oh"

The code says for each letter in "You got this!"

Only IF there's a letter in "oh"? (also doesn't make any sense to me)

There's an "o" in "You", and another one in "got".
