已知数组,求其均值和方差
好的,这是一个关于数据处理的问题。对于iris数据集中的四个列分别进行排序和去重,可以使用Python中的pandas和NumPy库进行处理。以下是可以实现该功能的代码:
```
import pandas as pd
import numpy as np
iris_data = pd.read_csv('iris.csv')
# 提取四列数据
col1 = iris_data['sepal_length']
col2 = iris_data['sepal_width']
col3 = iris_data['petal_length']
col4 = iris_data['petal_width']
# 对各列数据进行排序和去重
col1_sorted = np.sort(np.unique(col1))
col2_sorted = np.sort(np.unique(col2))
col3_sorted = np.sort(np.unique(col3))
col4_sorted = np.sort(np.unique(col4))
# 计算和、均值、标准差、方差、最小值、最大值
col1_sum = np.sum(col1)
col1_mean = np.mean(col1)
col1_std = np.std(col1)
col1_var = np.var(col1)
col1_min = np.min(col1)
col1_max = np.max(col1)
col2_sum = np.sum(col2)
col2_mean = np.mean(col2)
col2_std = np.std(col2)
col2_var = np.var(col2)
col2_min = np.min(col2)
col2_max = np.max(col2)
col3_sum = np.sum(col3)
col3_mean = np.mean(col3)
col3_std = np.std(col3)
col3_var = np.var(col3)
col3_min = np.min(col3)
col3_max = np.max(col3)
col4_sum = np.sum(col4)
col4_mean = np
