Python Quiz 12: Can You Guess the Output of this Python Code? | operators Quiz
Welcome to another Python coding quiz! In this video, Python operators are used to perform operations on variables and values. The code uses three types of operators: arithmetic, exponentiation and floor division.
The ** operator is used for exponentiation, which means raising a number to a power. For example, 2 ** 3 means 2 raised to the power of 3, which is 8.
The // operator is used for floor division, which means dividing two numbers and rounding down the result to the nearest integer. For example, 4 // 2 means 4 divided by 2, which is 2.
The + and - operators are used for addition and subtraction, respectively. For example, 8 + 2 means 8 plus 2, which is 10.
The order of operations in Python follows the PEMDAS rule: parentheses, exponentiation, multiplication/division, addition/subtraction. So, the code is evaluated as follows:
2 ** 3 + 4 // 2 - 1
= (2 ** 3) + (4 // 2) - 1
= (8) + (2) - 1
= 10 - 1
= 9
The final result is 9.
