Pandas Data validation
Data validation is an essential step in any data analysis or machine learning project. It involves checking data quality, consistency, and correctness to ensure that the data is reliable and suitable for the intended analysis or modeling. Pandas provides several functions and tools for data validation, such as checking for missing values, checking for duplicates, checking data types, and more. Here are some common data validation tasks in Pandas: (more…)
How to Parse HTML with Pandas
Pandas is a powerful data analysis library in Python, but it does not have a built-in parser for HTML. However, you can use the Beautiful Soup library along with Pandas to parse HTML and create a Pandas dataframe.
Here is an example of how to do it: (more…)
How to calculate the IQR in Pandas
To calculate the IQR (Interquartile Range) in Pandas, you can use the quantile() function to compute the 25th percentile (Q1) and the 75th percentile (Q3) and then subtract Q1 from Q3.
How to remove outliers in Pandas
There are several methods to remove outliers in Pandas, here are a few commonly used techniques: (more…)
How to subtract dates in Pandas
In Pandas, you can subtract two dates to get the time delta between them. The result will be a Timedelta object, which represents the difference between two dates or times in terms of days, seconds, microseconds, milliseconds, minutes, hours, weeks, or years.
For example, consider the following two dates: (more…)
How to join two dataframes
You can join two pandas DataFrames by using the merge method. The merge method takes two DataFrames as input and combines them into a single DataFrame based on a common column or columns.
Here’s an example of how to perform an inner join on two DataFrames based on a column named key: (more…)
How to calculate entropy in Pandas
To calculate entropy in Pandas, you can write a custom function that takes a Series of values as input and calculates the entropy using the formula: (more…)
How to VLOOKUP in Pandas
I try to show you how to vlookup in Pandas.
The VLOOKUP function in Excel is a popular function that allows you to search for a value in a table and return the corresponding value from another column. The equivalent of a VLOOKUP in Pandas is the merge method, which allows you to join two DataFrames based on a common column.
