Combine two columns of text in pandas dataframe

📝 Combine Two Columns of Text in Pandas Dataframe

Do you have a pandas dataframe with two separate columns of text and want to combine them into a single column? Well, you're in luck! In this blog post, we will address this common data manipulation issue and guide you through easy solutions to achieve your desired outcome. 💪

The Scenario

Let's start by setting the context. Imagine that you have a 20 x 4000 dataframe in Python, created using the pandas library. Among the columns, you have one named Year and another named quarter. Your goal is to create a new variable called period that combines the values from these two columns in a specific format.

Here's an example of what you're aiming for: if Year is equal to 2000 and quarter is equal to q2, you want the resulting period value to be 2000q2. Sounds simple enough, right? 🤔

Solution Steps

To achieve this, we can follow a straightforward process using pandas. Let's dive into the easy solutions:

1. First, make sure you have pandas installed in your Python environment. If you haven't done it already, you can install it by running the following command:

   pip install pandas

2. Import the pandas library into your Python script or Jupyter Notebook:

   import pandas as pd

3. Assuming you already have your dataframe loaded into a variable, let's call it df, you can add the period column by concatenating the Year and quarter columns, with the desired separator in between. Here's how you can do it:

   df['period'] = df['Year'] + df['quarter']

   As a result, the period column will be added to your dataframe, combining the values from Year and quarter.

An Example for Clarity

To illustrate the solution, let's consider an example with the following dataframe:

Year  quarter
0  2000      q2
1  2001      q3
2  2001      q4
3  2002      q1

After applying the solution, our dataframe will look like this:

Year  quarter   period
0  2000      q2  2000q2
1  2001      q3  2001q3
2  2001      q4  2001q4
3  2002      q1  2002q1

By leveraging pandas' ability to handle column operations, we successfully combined the Year and quarter columns into the newly created period column in the desired format.
