such as integers, strings, floating-point numbers, or Python objects. It organizes data sequentially and resembles a single column in an Excel sheet or SQL table. When we combine two pandas Series into a DataFrame results in a DataFrame with two columns. In this article, I will explain how...
So let's see several useful examples on how to combine several columns into one with Pandas. Suppose you have data like: 1: Combine multiple columns using string concatenation Let's start with most simple example - to combine two string columns into a single one separated by a comma: df['...

Notice that the axis=1 parameter makes the concatenation occur along columns rather than rows. Concatenation in pandas looks similar to this. Concatenation in pandas pandas has a function, pd.concat(), that can be used for a simple concatenation of Series or DataFrame objects, similar to np.co...
To combine two Pandas series into one, use the combine() method. It uses a specific function for the decision, mentioned as a parameter

Pandas is an open-source Python Library providing high-performance data manipulation and analysis tool using its powerful data structures. A Data frame is a two-dimensional data structure, i.e., data is aligned in a tabular fashion in rows and columns. Combine DataFrames using Inner Join ...
Example 1: Merge pandas DataFrames based on Index Using Inner JoinExample 1 shows how to use an inner join to append the columns of our two data sets.For this, we have to apply the merge function, and within the merge function we have to specify the left_index and right_index ...
