How do I combine multiple excel files into one? I am using Python and have access to Pandas and Numpy.
Here's a walkthrough and code with comments to help explain how to do that.

# Use Pandas, so first we import Pandas
import pandas as pd

# Using pandas, read an excel. Repeat as needed.
df1 = pd.read_excel('file1.xlsx')
df2 = pd.read_excel('file2.xlsx')
df3 = pd.read_excel('file3.xlsx')

# Combine the read files
df = pd.concat([df1, df2, df3])

# Write the combined files to a single Excel file
df.to_excel('combined.xlsx', index=False)

Please keep in mind, this code assumes that the Excel files have the same column names and types.
