使用缩进将for循环的主体与其余代码分开。 for循环流程图Python中for循环的流程图 示例:Python for循环 示例 #程序查找列表中存储的所有数字的总和 #数字清单 numbers = [6, 5, 3, 8, 4, 2, 5, 4, 11] # 用于存储总和的变量 sum = 0 # 遍历列表 for val in numbers: sum = sum+val print("总和...
Baseline: 9047.078 ns per loop Improved: 18.161 ns per loop % Improvement: 99.8 % Speedup: 498.17x 4、跳过不相关的迭代 避免冗余计算,即跳过不相关的迭代。 # Example of inefficient code used to find # the first even square in a list of numbers def function_do_something(numbers): for n in...
编写一个Python函数,接收一个整数列表作为参数,返回列表中所有偶数的平均值。```pythondef average_even(numbers):evens = [x for x in numbers if x % 2 == 0]if len(evens) == 0:return 0return sum(evens) / len(evens)numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]print(a

2 Python 嵌套 for 循环 在Python 中,for 循环用于迭代序列,例如列表、字符串、元组,以及其他可迭代对象,例如范围。在 Python 中使用嵌套 for 循环的语法: # outer for loop for element in sequence # inner for loop for element in sequence: body of inner for loop ...
Write a Python program to calculate the sum of the numbers in a list between the indices of a specified range. Sample Solution: Python Code: # Define a function 'sum_Range_list' that calculates the sum of a specified range within a listdefsum_Range_list(nums,m,n):# Initialize 'sum_ra...
