函数是一段可重复调用的代码块,它接收一些输入(参数),并可以输出一些结果(返回值)。我们讲解了函数的定义、调用、参数、返回值、作用域和递归函数等。
input[定义水果列表] loop[循环遍历列表] get_index[获取索引] calculate[计算水果名称长度] draw[绘制饼状图] end[结束] start --> input input --> loop loop --> get_index get_index --> calculate calculate --> draw draw --> loop loop -- 遍历完成 --> end 通过以上流程,我们可以清晰地了解...
I hope that from the above two sections, you understand how to get the index of the element in the iterable object using the for loop. Conclusion In this Python tutorial, you learned about aPython for loop with index, where you learned how to get the index value of an element or items...

for循环通常用于从定义循环边界的变量列表中访问成员变量的索引:for index in range(len(tips)):print(...

For & while else To break out of a for or while loop without a flag. for element in search: if element == target: print("I found it!") break else: print("I didn't find it!") while i < len(search): element = search[i] ...
Using a for loop is another way to get the index of the first element in my_list. Let’s take a look!for i in range(len(my_list)): if my_list[i] == 'a': first_index = i break print(first_index) # 0In this example, the for loop iterates over each index in the list ...
In Python, you can have an else block with a for loop, which is executed when the loop is finished. for i in range(3): print(i) else: print("Done") Iterating with index To iterate through a sequence along with the index, you can use the enumerate() function. ...
