How to Merge DataFrames in Pandas: Step-by-Step Code Solutions

Hello everyone, I am PiPi.

1. Introduction

A few days ago a member of the Python community asked a Pandas data‑merge question, as shown in the screenshot below.

2. Implementation

One user provided guidance, illustrated in the following image.

The code they shared is:

from pathlib import Path
with open('new.txt', 'a+') as f_new:
    for file in Path(r'你的目录').glob('*.txt'):
        with file.open() as f:
            f_new.writelines(f.readlines()[1:])

Another contributor posted additional code, shown in the images below.

The resulting output screenshot is shown below.

Both methods successfully solved the fan’s problem.

3. Summary

This article reviewed a Pandas data‑merge issue, provided detailed analysis and code implementations, and helped the community resolve the problem.

When posting large data files, remember to anonymize the data, share a small demo file, include copy‑able code, and attach error screenshots; if the code exceeds 50 lines, share it as a .py file.
