Moreover, once your data are in the DataFrame structure and the data are “clean,” you’ll still need to use some “data manipulation” techniques to analyze your data. Here, I’m talking about things like subsetting, grouping, and aggregating. Pandas has tools for performing all of these...
We hope this article has helped you find duplicate rows in a Dataframe using all or a subset of the columns by checking all the examples we have discussed here. Then, using the above-discussed easy steps, you can quickly determine how Pandas can be used to find duplicates....
# Custom function to highlight outliers def highlight_outliers(val): if val < lower_bound or val > upper_bound: return 'background-color: yellow; font-weight: bold; color: black' else: return '' df.style.applymap(highlight_outliers, subset=['Price']) ...
Pandas tolist() function is used to convert Pandas DataFrame to a list. In Python, pandas is the most efficient library for providing various functions to
import numpy as np DIS_subset = df_boston["DIS"] print(np.where(DIS_subset > 10)) Output: These are array indexes containing data points that are outliers as defined by the above criterion. At the end of the article, we will show you how to use these indices to remove outliers fro...
