Python读取文本文件中的数字以列表计算平均值

with open('data.txt', 'r') as file:
    lines = file.readlines()

numbers = []
for line in lines:
    words = line.split()
    for word in words:
        try:
            number = float(word)
            numbers.append(number)
        except ValueError:
            pass

average = sum(numbers) / len(numbers)

with open('data.txt', 'r') as file:

numbers = []
for line in lines:
    words = line.split()
    for word in words:
        try:
            number = float(word)
            numbers.append(number)
        except ValueError:
            pass

average = sum(numbers) / len(numbers)
print("平均值：", average)
