我有几个列表正在尝试输入数据框:
mydates = [0, 6, 15, 21, 30, 37, 45, 53]
prices = [30.4, 32.5, 31.7, 31.2, 32.7, 34.1, 35.8, 37.8]
mylist = [6.907894736842111, -2.461538461538464, -1.5772870662460567,4.807692307692319,
4.2813455657492305, 4.985337243401747, 5.5865921787709505, -3.9682539682539684]
我输入
df = DataFrame(prices, mylist, index=mydates, columns=['Prices', 'Percentage
s'])
并收到此错误:
Traceback (most recent call last):
File "<input>", line 1, in <module>
TypeError: __init__() got multiple values for keyword argument 'index'
如果我输入此内容,一切正常。
df = DataFrame(prices, index=mydates, columns=['Prices'])
有人可以告诉我如何解决问题吗?
答案 0 :(得分:1)
In [604]: d = {'dates' : mydates, 'prices': prices, 'mylist': mylist}
In [605]: df= DataFrame(d)
In [606]: print df
dates mylist prices
0 0 6.907895 30.4
1 6 -2.461538 32.5
2 15 -1.577287 31.7
3 21 4.807692 31.2
4 30 4.281346 32.7
5 37 4.985337 34.1
6 45 5.586592 35.8
7 53 -3.968254 37.8
编辑:
正如Wouter Overmeire指出的那样,您可以使用DataFrame({'prices': prices, 'mylist': mylist}, index=columnanme)
按列进行索引。
