1 载入数据

# Paths of the files to read
cancer_b_filepath = "../input/cancer_b.csv"
cancer_m_filepath = "../input/cancer_m.csv"

# Fill in the line below to read the (benign) file into a variable cancer_b_data
cancer_b_data = pd.read_csv(cancer_b_filepath,index_col="Id")

# Fill in the line below to read the (malignant) file into a variable cancer_m_data
cancer_m_data = pd.read_csv(cancer_m_filepath,index_col="Id")

step2 review the data

打印出肿瘤数据的前五行 benign

# Print the first five rows of the (benign) data
cancer_b_data.head()

打印出肿瘤数据的前五行 malignant

cancer_m_data.head()

找到数据

# Fill in the line below: In the first five rows of the data for benign tumors, what is the
# largest value for 'Perimeter (mean)'?
max_perim = 87.46

# Fill in the line below: What is the value for 'Radius (mean)' for the tumor with Id 842517?
mean_radius = 20.57

step4 a 曲线图下无阴影

sns.kdeplot(data=cancer_m_data['Radius (worst)'],label="Malignant") 
sns.kdeplot(data=cancer_b_data['Radius (worst)'],label="Benign") 

step4 a 曲线图下有阴影

sns.kdeplot(data=cancer_m_data['Radius (worst)'], shade=True, label="Malignant") 
sns.kdeplot(data=cancer_b_data['Radius (worst)'], shade=True, label="Benign")
