我必须从以下路径读取 pandas 的 CTG.xls 文件: https://archive.ics.uci.edu/ml/machine-learning-databases/00193/ .
从这个文件中我必须选择工作表数据。此外，我必须从文件的 K 列到 AT 列进行选择。所以最后我们得到了一个包含这些列的数据集:
["LB","AC","FM","UC","DL","DS","DP","ASTV","MSTV","ALTV","MLTV","宽度","Min","Max","Nmax","Nzeros","Mode","Mean","Median","Variance","Tendency","CLASS","NSP"]
如何使用 pandas 中的 read 函数来做到这一点？
最佳答案
用途:
url = 'https://archive.ics.uci.edu/ml/machine-learning-databases/00193/CTG.xls'
df = pd.read_excel(url, sheet_name='Data', skipfooter=3)
df = df.drop(columns=df.filter(like='Unnamed').columns)
df.columns = df.iloc[0].to_list()
df = df[1:].reset_index(drop=True)
输出
LB AC FM UC DL DS DP ASTV MSTV ALTV MLTV Width Min Max Nmax Nzeros Mode Mean Median Variance Tendency CLASS NSP
