这个函数用于演示如何在Python中编写一个示例函数，我们将使用小标题和单元表格来组织代码。

导入所需库

import pandas as pd
import numpy as np

定义示例函数

def performs_example(data, operation):
    if operation == "sum":
        result = np.sum(data)
    elif operation == "mean":
        result = np.mean(data)
    elif operation == "max":
        result = np.max(data)
    elif operation == "min":
        result = np.min(data)
    else:
        raise ValueError("Invalid operation. Please choose from 'sum', 'mean', 'max', or 'min'.")
    return result

使用示例函数

data = [1, 2, 3, 4, 5]
sum_result = performs_example(data, "sum")
print(f"Sum of the data: {sum_result}")
mean_result = performs_example(data, "mean")
print(f"Mean of the data: {mean_result}")
max_result = performs_example(data, "max")
print(f"Max value of the data: {max_result}")
min_result = performs_example(data, "min")
print(f"Min value of the data: {min_result}")

输出结果：

Sum of the data: 15
Mean of the data: 3.0
Max value of the data: 5
Min value of the data: 1

以下是一个介绍，展示了不同的input_value和函数返回的output_value：

def performs_example_function(input_value):
    return input_value ** 2

print("输入值 (input_value) | 输出值 (output_value)")
print("")
example_values = [0, 1, 2, 3, 4]
for value in example_values:
    output = performs_example_function(value)
    print(f"{value:18} | {output:18}")
