如果我想基于“ GameWeek”值对其进行过滤，请像这样传递变量：

gameweek = 15

只需：

filtered_df = df[df['GameWeek']==gameweek]

我将获得'GameWeek'为15的所有行。

问题

但是，如果我传递相同的变量gameweek，那么pandas怎么给我从'GameWeek'1到15的所有行？

我所有的查询都应该像这样：[:gameweek]

Answer 1

使用df.le()，基本上小于等于（{<=）：

filtered_df = df[df['GameWeek'].le(gameweek)]

OR

您还可以使用实际的<=运算符：

filtered_df = df[df['GameWeek'] <= gameweek]

Answer 2

您是说要获取GameWeek范围从1到15的值吗？一种可能的方法是在range()方法中查询.isin()。

filtered_df = df[df['GameWeek'].isin(range(1,16))
