从.dat文件计算平均值

Question

我是新来的在python上读取文件的人。我正在尝试计算.dat文件中每一列的平均值。

我的代码未运行，并且未显示任何错误。

import pandas as pd    

with open('airfoil_self_noise.dat') as f:
    next(f) # skip first row
    df = pd.DataFrame(l.rstrip().split() for l in f)

print(df)


def average_column (df):
    f = open(df,"r")
    average = 0
    Sum = 0
    row_count = 0
    for row in f:
        for column in row.split(','):
            n=float(column)
            Sum += n
        row_count += 1
    average = Sum / len(column)
    f.close()
    return 'The average is:', average
