• Pandas Weighted Average

  The weighted average is the average of the data that identifies the specific numbers that are more important than the other numbers in the DataFrame. We will be implementing all possible ways in which the Pandas weighted average can be calculated with the help of several examples.

• Pandas Case When

  In this tutorial, we will perform different operations by using case statements and if-else statements. A case statement makes it possible to compare the value of a variable to a range of potential values. When the set of values is referred to or passed in the case statement, each value inside the set is checked by the cases or conditions inside the statement.

  Case statement in the Pandas DataFrame provides an output or returns a value if the condition is satisfied.

• Pandas - Convert Categorical Values to Int Values

  The datasets for machine learning execution include both numerical and categorical variables. Categorical variables are string-type data that humans easily comprehend. Machines, on the other hand, cannot understand categorical inputs directly. Consequently, categorical content must be transformed into numerical values that machines can interpret.

• Get the Pandas DataFrame Rows Based on Index

  Basically, a Pandas DataFrame has two indices. These indices are distinguished by their axis. The row index is an index that is located along axis 0 (horizontal), whereas the column index is an index that is located along axis 1 (vertical).

  In this article, we will use iloc[] and loc[] functions to get the rows from the DataFrame. We need to specify the row and column ranges (start and end locations along the columns or rows). The location-based indexing can be used to query the Pandas DataFrames.

• Pandas Json Normalize

  The “JSON” basically stands for the “JavaScript Object Notation”.

  Pandas has the most popular “data processing framework” in Python, which is the “JSON” normalize” feature. It is a built-in feature of Pandas. It is the simplest way to do the Pandas JSON normalization() using the “Python” request modules.

  In this article, we will see different levels of normalization.
