The ternary Expression is useful in cases where we need to assign a value to a variable based on a simple condition, and we want to keep our code more concise — all in just one line of code. Since Python supports short circuiting, in the expression a or b, b won't be evaluated if a is True. In your example, we have '' or 'Trondheim' or 'Hammer Dance'. This expression is evaluated from left to right, so the first thing being evaluated is '' or 'Trondheim', or in other words False or True, which returns True.Feb 8, 2024 · In Python, blocks are expressed with indentation (usually four spaces) rather than brackets.

From Python documentation: The expression x and y first evaluates x; if x is false, its value is returned; otherwise, y is evaluated and the resulting value is returned. Basically, it evaluates the last integer in your case which is true.Using Bitwise AND operator. The idea is to check whether the last bit of the number is set or not. If last bit is set then the number is odd, otherwise even. If a number is odd & (bitwise AND) of the Number by 1 will be 1, because the last bit would already be set.
