We don't normally use comparison operators for booleans like you do in

  while guessed==False : 

Instead, we can use

  while not guessed :

(same as the code that you have) or

  while guessed :

(opposite to the code you have - runs while true)

The reason for this is that doing another comparison is simply an overkill. The statement is going to evaluate to a boolean anyway, so why not use the one that you already have, and invert if necessary? To check if something is true, comparison actually does nothing, and in this example negation (with not) is slightly faster and easier to read than what you have.

Either: Put spaces around your all of your operators for readability, or stick to not using spaces around any of your operators - don't mix and match like you do in this program.

Do note however that although it is good to be consistent, it is even better to stick with standards and simply put spaces around all of your operators.
