Python,又有不懂了。 这是题目,只有英文的: Write a function average that takes a list of numbers an
Python 3.x doesn’t have a built-in method to calculate the average. Instead, simply divide the sum of list values through the number of list elements using the two built-in functionssum()andlen(). You calculate the average of a givenlistin Python assum(list)/len(list). The return va...
函数名:小写,可以用下划线风格单词以增加可读性。如:myfunction,my_example_function。注意:混合大小写仅被允许用于这种风格已经占据优势的时候,以便保持向后兼容。有的人,喜欢用这样的命名风格:myFunction,除了第一个单词首字母外,后面的单词首字母大写。这也是可以的,因为在某些语言中就习惯如此。但我不提倡,这是我...

Average Grade: 86.4 In the exercise above, we declare a "Student" NamedTuple with the fields 'name', 'age', and 'marks'. The "calculate_average_grade()" function takes a "Student" NamedTuple as input, calculates the average grade from the 'marks' field, and returns it. Next, we c...
滚动计算函数: 移动平均值(Moving Average): import pandas as pd data = {'column': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]} df = pd.DataFrame(data) df column df['MA'] = df['column'].rolling(window=3).mean() df 其中,window=3表示窗口大小为3,即计算每3个数据的平均值。
