The following Python code retains only those rows that are not duplicated in the variables x1 and x2:data_new2 = data.copy() # Create duplicate of example data data_new2 = data_new2.drop_duplicates(subset = ['x1', 'x2']) # Remove duplicates in subset print(data_new2) # Print ...
Python program to drop row if two columns are NaN# Importing pandas package import pandas as pd # Importing numpy package import numpy as np # Creating two dictionary d = { 'a':[0.9,0.8,np.nan,1.1,0], 'b':[0.3,0.5,np.nan,1,1.2], 'c':[0,0,1.1,1.9,0.1], 'd':[9,8,0,...
The argument to thelabelsparameter is the ‘label’ of the row fromthe dataframe index. You can use either a single row label, or multiple labels inside of a Python list. This is fairly simple to do, but to do it properly, you really need to understand Python dataframe indexes. If you...
df.index[[1,3]] gets you row labels for the 2nd and 3rd rows, bypassing these to drop() method removes these rows. Note that in Python, the list index starts from zero.# Delete Rows by Index numbers df = pd.DataFrame(technologies,index=indexes) df1=df.drop(df.index[[1,3]]) prin...

This article explores different methods to delete specific rows in Pandas data frame using Python.Most data engineers and data analysts use Python because of its amazing ecosystem of data concentrated packages. A few of them are Pandas, Matplotlib, SciPy, etc....
The thresh parameter refers to threshold. This parameter lets you set the minimum number of non-NaN values a row or column needs to avoid being dropped by dropna(). To remove specific rows from the DataFrame, set thresh to 12.Python 复制 ...
Thethreshparameter is used when we want to drop rows if they have at least a specific number of non-NaN values present. For instance, if you want to delete a row if it has less than n non-null values, you can pass the number n to thethreshparameter. ...
