To concatenate DataFrames, use theconcat()method. By default, the method concatenates the given DataFrames vertically (i.e., row-wise) and returns a single DataFrame containing values from the given DataFrames. In the below example,concatenates the DataFramesdfanddf1along the rows (axis=0), p...
Use theconcat()Function to Concatenate Two DataFrames in Pandas Python Theconcat()is a function in Pandas that appends columns or rows from one dataframe to another. It combines data frames as well as series. In the following code, we have created two data frames and combined them using the...
Combine DataFrame objects with concat() For stacking two DataFrames with the same columns on top of each other — concatenating vertically, in other words — Pandas makes short work of the task. The example below shows how to concatenate DataFrame objects vertically with the default parameters. I...

Pandas, a popular Python library for data manipulation and analysis, provides a concat() function that allows you to combine tables either horizontally or vertically. In this article, we will demonstrate how to use the concat() function in pandas to concatenate tables horizontally and vert...
DataFrame({"dat2": [7, 6]}) print(dat2) Output: dat2 0 7 1 6 As we can see for both dat1 and dat2, we have 2 columns and 2 rows where one indicates the index and the second shows the values in our data frame. Use concat() to Append a Column in Pandas We can use ...
Pandas is a special tool that allows us to perform complex manipulations of data effectively and efficiently. In a DataFrame, each row is assigned with an index value ranging from 0 ton-1. The 0this the first row andn-1thindex is the last row. Pandas provides us the simplest way to co...
In conclusion, Pandas provides several ways to concatenate column values in a DataFrame. Two approaches were discussed in this tutorial: using the pd.Series.str.cat() method and using the pd.concat() function. Depending on your specific use case, one of these approaches may be more suitable ...
