从 .txt 文件中读取数据并在 Python 中计算平均值

Question

I have a question about my Python code. I would like to read data from a .txt file and calculate the average of these values. The format of the .txt file is (1 vertical column):

1.36
5.5
6.11
12.05
25.8
38.28

The code that I have written is:

 from statistics import mean

 with open('inputdata.txt','r') as fin:
     data=fin.read().split('\n')
     for index in range(len(data)):
         average=mean(float(index))

  print(average)

I used the above code, but in command window shows the following message:

if iter(data) is data:
TypeError: 'float' object is not iterable

Could anyone help me?

Answer 1

You can create a list of values by splitting by '\\n' and convert those values to float, after that you can calculate the mean of that list using the mean from statistics:

from statistics import mean

with open('inputdata.txt','r') as fin:
    data=[float(x) for x in fin.read().split('\n')]

average = mean(data)
print(average)
