否则: print('能被 2 整除但不能被 3 整除') 否则如果 x%3 == 0: print('能被 3 整除但不能被 2 整除')py The `elif` in the above code stands for “else if.” It is often convenient to use a **compound Boolean expression** in the test of a conditional, for example,如果 x < ...
Logic Programming uses facts and rules for solving the problem. That is why they are called the building blocks of Logic Programming. A goal needs to be specified for every program in logic programming. To understand how a problem can be solved in logic programming, we need to know about th...
In this example, we initialize a list of boolean values representing the primality of each number. We then mark the multiples of each prime number asFalse. Finally, we print the numbers that remainTrue. Here is the exact output in the screenshot below: Check outWrite a Program to Check Wh...
上下文管理器对象存在以控制with语句,就像迭代器存在以控制for语句一样。 with语句旨在简化一些常见的try/finally用法,它保证在代码块结束后执行某些操作,即使代码块由return、异常或sys.exit()调用终止。finally子句中的代码通常释放关键资源或恢复一些临时更改的先前状态。
Python prime_v1.py import math def is_prime(number): if number <= 1: return False for i in range(2, int(math.sqrt(number)) + 1): if number % i == 0: return False return True This is a Boolean-valued function, also known as a predicate function, that returns True if the...

Note : A prime number (or a prime) is a natural number greater than 1 and that has no positive divisors other than 1 and itself. Click me to see the sample solution 10. Print Even Numbers from a Given List Write a Python program to print the even numbers from a given list. ...
A program’s state can be many different things. A few common ones that I deal with almost daily is configuration. Some command-line tools, for example, allow to configure them with configuration files in the file system. The idea is that you can have some configuration done in the file,...
