For example, # iterate from i = 0 to 3 for _ in range(0, 4: print('Hi') Run Code Output 0 1 2 3 Here, the loop runs four times. In each iteration, we have displayed Hi. Since we are not using the items of the sequence(0, 1, 2 and 4) in the loop body, it is ...

for i in myList: print (i) 1. 2. As we can see we are using a variablei, which represents every single element stored in the list, one by one. Our loop will run as many times, as there are elements in the lists. For example, inmyListthere are 6 elements, thus the above loop...
5、代码合并 在某些情况下,直接将简单函数的代码合并到循环中可以提高代码的紧凑性和执行速度。 # Example of inefficient code # Loop that calls the is_prime function n times. def is_prime(n): if n <= 1: return False for i in range(2, int(n**0.5) + 1): if n % i == 0: return ...

Else in For Loop Theelsekeyword in aforloop specifies a block of code to be executed when the loop is finished: Example Print all numbers from 0 to 5, and print a message when the loop has ended: forxinrange(6): print(x)
Using python for loop This version offor loopwill iterate over a sequence of numbers using therange() function. The range() represents an immutable sequence of numbers and is mainly used for looping a specific number of times in for loops. Note that the given end point in the range() is...
5. 在这个示例中,我们使用一个计数器变量count来控制循环次数,当计数器小于50时继续循环,每次循环结束后计数器加1。 4. 类图 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...
