Why does IF statement fail?

I have a horrible feeling that the answer to this question is going to be obvious, but...

I am reading data from a small file in MicroPython. The value of the line I read determines whether a bool variable, debug is set or not. I have tried this two ways:

        s = f.readline()
        print("s = ",s)
        if s == "1":
            debug = True
        else:
            debug = False
        print("debug = ",debug)

and

        s = f.readline()
        print("s = ",s)
        debug = True if s == "1" else False
        print("debug = ",debug)

In both cases, the printed output is:

s =  1
debug =  False

I have also tried removing the quotes from around the 1 in case it's reading this as an integer rather than a string, but the result is the same. This is silly! What am I missing?

Solution

  • Is there a "\n" on the end of s perhaps, so s == "1\n"?
