For school I have a DataFrame (containing of multiple columns and rows) and my task is to create a new column in that DataFrame that contains 'true' if the value of a column in that dataframe is higher than a certain value and the new column should contain 'false' if the value is lower than the value from a column in the dataframe. Can somebody please help me out? (I'm supposed to do this in jupyter-notebook)
Try:
import numpy as np
df[<new col>] = np.where(df[<value col>] > <threshold>, True, False)
But replace <new col>
with the string name of your new column, <value col>
with the string name of the column you're comparing, and replace <threshold>
with the compared value.
Try
df['flag'] = True
df.loc[df['A']>2,'flag'] = False
