In short, the code inside thecontrol flow statement(if name equals main) is executed only when the script is run from the command line or through anIDE. It is not executed when it is used as a module by another Python script. With this idiom, you can ensure that your Python script be...
continue 语句表示继续执行循环的下一次迭代: >>> for n in range(2, 10): ... for x in range(2, n): ... if n % x == 0: ... print(n, 'equals', x, '*', n//x) ... break ... else: ... print(n, 'is a prime number') ... 2 is a prime number 3 is a prime ...
if(person1equals(person2)){ Systemoutprintln("这两个人的属性是相等的。"); } } } ``` 从这个例子可以看出,对于复杂的对象类型,我们需要更细致地考虑相等判断的方式,而if语句仍然是在这个判断过程中起核心的控制作用。 在C++语言里,相等判断也类似。假设我们有一个变量x,判断它是否等于100的代码如下: `...
