我的df有3栏
df = pd.DataFrame({"col_1": (0.0, 0.0, 1.0, 1.0, 0.0, 1.0, 1.0),
"col_2": (0.0, 0.24, 1.0, 0.0, 0.22, 3.11, 0.0),
"col_3": ("Mon", "Tue", "Thu", "Fri", "Mon", "Tue", "Thu")})
我想删除df.col_1为1.0且df.col_2为0.0的行。因此，我会得到：
df = pd.DataFrame({"col_1": (0.0, 0.0, 1.0, 0.0, 1.0),
"col_2": (0.0, 0.24, 1.0, 0.22, 3.11),
"col_3": ("Mon", "Tue", "Thu", "Mon", "Tue")})
我试过了：
df_new = df.drop[df[(df['col_1'] == 1.0) & (df['col_2'] == 0.0)].index]
它给了我错误：
'method' object is not subscriptable
任何想法如何解决上述问题？
