df = pd.read_csv('D:\\project_codes\\USA_Presidential_Contributor\\2012-P00000001-ALL.csv',index_col=False)
看看官方解释
index_col : int or sequence or False, default None Column to use as the row labels of the DataFrame. If a sequence is given, a MultiIndex is used. If you have a malformed file with delimiters at the end of each line, you might consider index_col=False to force pandas to not use the first column as the index (row names)
index_col默认不使用数据表的列作为行标签，不过如果列名数小于数据的列数，可以指定某些列为行标签。如下面的数据，列名数比数据列数少3个，可以指定3列为行标签（索引）。index_col=False to force pandas to _not_use the first column as the index (row names)
data = pd.read_csv("./data/stock_day2.csv",index_col=[4,6,7]) data.head()
