Union of Dataframe 1 and 2: No duplicates now Concat horizontallyTo concatente dataframes horizontally (i.e. side-by-side) use pd.concat() with axis=1:import pandas as pd df1 = pd.DataFrame({ 'name':['john','mary'], 'age':[24,45] }) df2 = pd.DataFrame({ 'name':['mary','...
Concatenation in the context of Pandas DataFrames refers to combining two or more DataFrames along a specified axis (either rows or columns). It is a way to vertically or horizontally stack DataFrames to create a larger DataFrame. How do I perform a union of two Pandas DataFrames using pd....

Similarly, you can concatenate more than two pandas Series horizontally using the concat() function. For that, you need to set theaxisparam of theconcat()function is1and pass it into this function along with the specified number of Series. It will stack them horizontally and form a new Seri...
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...
If you installed Pandas with pip, NumPy should already be installed. Type the following code in your Python shell or script file: import numpy as np df_first = pd.DataFrame({'COL 1': ['X', 'X', np.nan], 'COL 2': ['X', np.nan, 'X'], 'COL 3': [np.nan, 'X', 'X']...
I have 2 dataframes that I try to concatenate horizontally. The method concat doesn't work: it returns a dataframe with a wrong dimension. Moreover, all column names happen to be changed to numbers going from 0 to 64... The dataframes are created from a dataset that is a bit big so...

objs: This is a list or dictionary of pandas objects to be concatenated. You can combine Series and DataFrame objects in various ways. axis: The axis to concatenate along.axis=0is the default and will stack the objects vertically (i.e., append rows).axis=1will stack them horizontally (i...
