    Pandas进阶及技巧

     

    1. 创建Pandas

     
     
     
     
     
     
    import pandas as pd
    country1 = pd.Series({'Name': '中国',
                        'Language': 'Chinese',
                        'Area': '9.597M km2',
                         'Happiness Rank': 79})
    country2 = pd.Series({'Name': '美国',
                        'Language': 'English (US)',
                        'Area': '9.834M km2',
                         'Happiness Rank': 14})
    country3 = pd.Series({'Name': '澳大利亚',
                        'Language': 'English (AU)',
                        'Area': '7.692M km2',
                         'Happiness Rank': 9})
    df = pd.DataFrame([country1, country2, country3], index=['CH', 'US', 'AU'])
     
     
     
     
     
     
     
     
    # 注意在jupyter中使用print和不使用print的区别
    print(df)
    df

    # 添加数据
    # 如果个数为1,会自动进行“广播”操作
    # 如果大于要求的个数,会报错
    #如果刚好等于要求的个数,会依次填充字段属性值
    df['Location'] = '地球'
    print(df)
    df['Region'] = ['亚洲', '北美洲', '大洋洲']
    print(df)
    df

    2. Pandas索引

     
     
     
     
     
     
    # 行索引
    print('loc:')
    print(df.loc['CH'])
    print(type(df.loc['CH']))
    print('iloc:')
    print(df.iloc[1])
     
     
     
    loc:

    <class 'pandas.core.series.Series'>
    iloc:

    # 列索引
    print(df['Area'])
    print(type(df['Area']))
     
     
     
    CH    9.597M km2
    US    9.834M km2
    AU    7.692M km2
    Name: Area, dtype: object
    <class 'pandas.core.series.Series'>
    
     
     
     
     
     
     
    # 获取不连续的列数据
    print(df[['Name', 'Area']])

    # 混合索引
    # 注意写法上的区别
    print('先取出列,再取行:')
    print(df['Area']['CH'])

    3. 删除数据

     
     
     
     
     
     
    print(df.drop(['CH']))
    # 注意drop操作只是将修改后的数据copy一份,而不会对原始数据进行修改
    print(df)

    print(df.drop(['CH'], inplace=True))
    # 如果使用了inplace=True,会在原始数据上进行修改,同时不会返回一个copy
    print(df)

    4. DataFrame的操作与加载

     
     
     
     
     
     
    # 注意从DataFrame中取出的数据进行操作后,会对原始数据产生影响
    ranks = df['Happiness Rank']
    ranks += 2
    print(ranks)
    print(df)
