foriteratorinsequence: block of statementselse: block of statements 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. Note tha...

# (Length calculation outside for loop) deftest_02_v1(numbers): my_list_length=len(numbers) output_list=[] foriinrange(my_list_length): output_list.append(i*2) returnoutput_list 通过将列表长度计算移出for循环,加速1.6倍,这个方法可能很少有人知道吧。
Unlike thefor loop, thewhile loopdoesn’t iterate over a sequence. It uses the comparison operators and booleans for its condition. Let’s look at some examples to better understand how it is used. Example 1:Print “Hello World!” a count number of times ...

下面是一个简单的类图示例,表示一个名为Loop的类,其中包含一个循环50次的方法loop_50_times: Looploop_50_times() 在这个类图中,Loop类包含一个名为loop_50_times的方法,用于循环50次。 5. 结论 通过本文的介绍,我们学习了如何在Python中使用循环进行重复操作,并且实现了循环50次的示例。循环是编程中常用的控...
