How can I use pandas to concatenate DataFrames?

You can use the pd.concat() function to concatenate DataFrames along a particular axis. Would you like an example?

Yes, please provide an example of concatenating two DataFrames.

Sure! Here's a simple example:

import pandas as pd

df1 = pd.DataFrame({'A': [1, 2], 'B': [3, 4]})
df2 = pd.DataFrame({'A': [5, 6], 'B': [7, 8]})

result = pd.concat([df1, df2])
print(result)

This will concatenate df1 and df2 vertically.

What if I want to concatenate them horizontally?

You can set the axis parameter to 1 in the pd.concat() function:

result = pd.concat([df1, df2], axis=1)
print(result)

This will concatenate the DataFrames side by side.
