Finally, you can also use the left shift (<<) and right shift (>>) operators to slide masks into place.

a = 0b101 # Tenth bit mask mask = (0b1 << 9) # One less than ten desired = a ^ mask

Let’s say that I want to turn on the 10th bit from the right of the integer a.

Instead of writing out the entire number, we slide a bit over using the << operator.

We use 9 because we only need to slide the mask nine places over from the first bit to reach the tenth bit.

Instructions

Define a function called flip_bit that takes the inputs (number, n).

Flip the nth bit (with the ones bit being the first bit) and store it in result.

Return the result of calling bin(result).
