我正在尝试为aruba加载gdp数据，如下所示：
block我一直在LABELS = ["Country Name","1995","1996","1997","1998","1999","2000","2001","2002","2003","2004","2005","2006","2007","2008","2009"]
RATES = ["Aruba","1.24508591166203","7.81443171889218","6.66662183020206","1.15446939174406","4.51406203251221","-0.364695778713454","-2.16445940890385","0.465289865491144","7.51947237328494","1.17669048367502","0.380390971382511","2.35511944298051","-3.65462624193272","-6.88130206359888","-5.65350208612952"]
df = pd.DataFrame.from_records(data=RATES, columns=LABELS)
#print(df.head())
print(len(LABELS))
print(len(RATES))
。
但是LABELS和RATES的长度是一样的，16。
我做错了什么？
答案 0 :(得分：1)
你需要：
df = pd.DataFrame.from_records(data=[RATES], columns=LABELS)
这样做的原因是此方法假定您正在获得一个可迭代列表。字符串是可迭代的，因此它假定每个字符都应该是一个值。通过说[RATES]，你清楚地表明列表应该只是一行。
df = pd.DataFrame.from_records(data=RATES)
print(df)
