This article shows you how to calculate the average of a given list of numerical inputs in Python. In case you’ve attended your last statistics course a few years ago, let’s quickly recap the definition of the average: sum over all values and divide them by the number of values. So...
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
Example 2:Let’s create a list of 3 strings and return the index position of the minimum element. # Consider the list of stringslanguages=["punjabi","tamil","malayalam"]# Using for loopminimum_element=languages[0]foriinrange(1,len(languages)):if(languages[i]<minimum_element):minimum_elem...

Write a Python program to calculate the average value of the numbers in a given tuple of tuples.Sample Solution:Python Code:# Define a function named 'average_tuple' that takes a tuple of tuples 'nums' as input. def average_tuple(nums): # Calculate the average values of the numbers ...
在Python中,规定了一种定义函数的格式,下面的举例就是一个函数,以这个函数为例来说明定义函数的格式和调用函数的方法。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 defadd_function(a,b):#冒号必须 c=a+b #缩进必须returncif__name__=="__main__":result=add_function(2,3)print result #pytho...
