python - 根据条件提取行 - Pandas

Question

我想从'route_id'= 6A的df中提取所有行。

这是我尝试过的，但它返回语法错误：

 df.loc(df['route_id'] = 6A)

有小费吗？提前致谢。

Answer 1

Looks like you've used the assignment = instead of equality test ==. The .loc needs square brackets and I also added some quotes around the '6A'

df.loc[df['route_id'] == '6A']
