在.txt文件python中查找平均值 [英] Finding average in .txt file python

问题描述

我需要从.txt文件中打印出平均高度.我如何以一种简单的方式编写它?.txt文件具有以下数字:

i need to print out average height from a .txt file. How do I write it in an easy way? The .txt file has these numbers:

12
14
59
48
45
12
47
65
152

这是我到目前为止所得到的:

this is what i've got so far:

import math

text = open(r'stuff.txt').read()
data = []
with open(r'stuff.txt') as f:
    for line in f:
        fields = line.split()
        rowdata = map(float, fields)
        data.extend(rowdata)

biggest = min(data)
smallest = max(data)
print(biggest - smallest)

推荐答案

要计算某些数字的平均值，应将它们求和，然后除以数字数:

To compute the average of some numbers, you should sum them up and then divide by the number of numbers:

data = []
with open(r'stuff.txt') as f:
    for line in f:
        fields = line.split()
        rowdata = map(float, fields)
        data.extend(rowdata)

print(sum(data)/len(data))
