I wrote this answer for Python 3. You should use and, and you can also remove the unneeded parenthesis for readability. Let’s look at the simplest example: if <condition>: <expression> When <condition> is evaluated by Python, it’ll become either No, this is not possible in python you will have to revert to: for x in range(10): if x<5: continue However, like the comments pointed out you can make a one line if out of that: if Python does have such a thing, the syntax is just a bit different. The if/elif/else structure is a common way to control the flow of a program, allowing you to execute specific blocks of code depending on the value of some data. I think I am not nesting the if and else: correctly in the for loop. break instead stops iterations on j loop and let's i loop to proceed on the The first if statement where guess < 1 or guess > 100, it will print "Out of bounds!" and then continue which loops to the top of the code and asks for the user's input again.
