根据列值对Pandas Dataframe排序

Question

enter image description here

In my data set in height column value increases then after starts to decrease. I want to sort data only up to increase height. I don't want data after height decrease.

Answer 1

You can achieve this by finding the index of the max value of the height column, and then using iloc to reassign the dataframe only including the rows up to this index:

x = df.idmax()['height']
df = df.iloc[:x+1]
