By default, while creating DataFrame, Python pandas assign a range of numbers (starting at 0) as a row index. Row indexes are used to identify each row. We can set a new row index or replace the existing ones usingDataFrame.set_index()function, which we discuss further in more detail. ...
The Python set() function is used to create a new set. A set is a collection of unique elements, meaning that each item appears only once in the set.It is an unordered and mutable (changeable) data structure that allows you to store different types of data, such as numbers, strings, ...
Index can be set while creating a pandas DataFrame, useset_index()method to set indices to existing DataFrmae. You can also set index from a List, Series or DataFrame. hence, you can have mutliple indices to the DataFrame. Theset_index()function allows you to set one or more columns ...
Series-set_axis() function The set_axis() function is used to assign desired index to given axis. Indexes for column or row labels can be changed by assigning a list-like or Index. Changed in version 0.21.0: The signature is now labels and axis, consistent with the rest of pandas API...
Example 2: Exchange Particular Values in Column of pandas DataFrame Using replace() Function In this example, I’ll show how to replace specific values in a column by a new value. For this task, we can use the replace() function as shown below: ...
