As you can see in the above program, all we did was, we started by adding a condition to theifblock, and then used anotherif-elseblock in itselseblock. And we kept on doing the nesting until all the conditions were taken care of. This, however, is a little tedious than usingelif....

这是最简单的编程功能。IF 测试我们要看的下一个编程功能是if语句和它的派生物——elif和else。正如您所料,if执行一个测试,然后根据测试结果从备选方案中进行选择。最基本的if语句是这样的:>>> if 1: ... print 'true' ... true 1与布尔值true相同,所以前面的语句将总是打印true。
In this example, because number = 42, the conditions are true, and all() returns True. You can play with the value of number if you’d like to experiment a bit.In the final two examples, you use the callable() function. As its name suggests, this function allows you to determine ...
The below example shows else if statements with the preceding conditions are as follows. We have declared two-variable names as py1 and py2 and assigned 15, 25 values to them. After declaring the value the condition statement is checking the true condition in the first if statement. Then it...
