1. Series系列

ser1 = pd.Series([1,2,'a'],index=['a','b','c'])
print(ser1)
ser2 = pd.Series({'a':[1,2,3],'b':['1','2','3']})
print(ser2)
d=[[1.3,2.0,3,4],[2,4,1,4],[2,5,1.9,7],[3,1,0,11]]
print(d)
df = pd.DataFrame(d,index=['a','b','c','d'],columns=['A','B','C','D'])
print(df)



d={'color':['blue','green','yellow','red','while'],
    'object':['ball','pen','pencil','paper','mug'],
    'print':[1.2,1.0,0.6,0.9,1.7]}
frame = pd.DataFrame(d, index=['a','b','c','d','e'])
peint(frame)
