[966] Merge two DataFrames horizontally
In Pandas, you can use the pd.concat
function to merge two DataFrames horizontally (i.e., along columns). Here's an example:
import pandas as pd # Sample DataFrames df1 = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]}) df2 = pd.DataFrame({'C': [7, 8, 9], 'D': [10, 11, 12]}) # Concatenate along columns (axis=1) result = pd.concat([df1, df2], axis=1) print(result)
In this example, pd.concat([df1, df2], axis=1)
concatenates df1
and df2
along columns, creating a new DataFrame result
with columns from both df1
and df2
. The axis=1
parameter specifies the concatenation along columns.
You can adjust column names and indexes based on your specific use case and data.
