方法一：用pandas.Series集合构建DataFrame

import pandas as pd

"""2维数据结构练习"""

df ={
'name': pd.Series(["monica","jessica","laura"],index=[1,2,3]),
'age': pd.Series(["18","19","20"],[1,2,3]),
'nationality': pd.Series(["chinese", "american", 'japanese'],[1,2,3])
}

data = pd.DataFrame(df)
print(data)

方法二：用字典创建DataFrame

import pandas as pd

data ={
'name': ["monica","jessica","laura"],
'age': ["18","19","20"],
'nationality':["chinese","american","japanese"]
    }

df = pd.DataFrame(data, index=[1,2,3])

显示结果：

      name age nationality

1   monica  18     chinese

2  jessica  19    american

3    laura  20    japanese
