Example 1 - Using range function to loop n times The example here iterates over the range of numbers from 1 to 10 and prints its value. However, if it reaches the number divisible by 5, it will break the loop.
这些包括comb和factorial函数,它们在各种应用中非常有用。使用参数n和k调用的comb函数返回从n个项目的集合中选择k个项目的方式数,如果顺序不重要且没有重复。例如,先选择 1 再选择 2 与先选择 2 再选择 1 是相同的。这个数字有时被写为*^nC[k]。使用参数n调用的阶乘函数返回阶乘n! = n(n-1)(n-2)*…...

同样的,把函数改成generator后,我们基本上从来不会用next()来调用它,而是直接使用for循环来迭代: Similarly, after changing the function to the generator, we basically never involke it with next(), but instead use the for loop to iterate: >>>forninfib(6): ...printn ...1 1 2 3 5 8 Ref...

To iterate over the values rather than the keys, you use the dictionary’s values() function: >>> for value in accusation.values(): ... print(value) ... ballroom lead pipe Col. Mustard To return both the key and value as a tuple, you can use the items() function: >>> for item...
Instead of writing the same thing three times, we might find it easier to use a for-loop to iterate through multiple elements. Consider, for example: if we wanted to iterate through the entire /24 subnet of IP addresses for 192.168.95.1 through 192.168.95.254, using a for-loop with the ...
