Python - Reverse the column order of the Pandas DataFrame

PythonServer Side ProgrammingProgramming

To reverse the column order, use the dataframe.columns and set as -1 −

dataFrame[dataFrame.columns[::-1]

At first, import the required library −

import pandas as pd

Create a DataFrame with 4 columns −

dataFrame = pd.DataFrame({"Car": ['BMW', 'Lexus', 'Tesla', 'Mustang', 'Mercedes', 'Jaguar'],"Cubic_Capacity": [2000, 1800, 1500, 2500, 2200, 3000],"Reg_Price": [7000, 1500, 5000, 8000, 9000, 6000],"Units_Sold": [ 100, 120, 150, 110, 200, 250]
})

Reverse the column order −

df = dataFrame[dataFrame.columns[::-1]]

Example

Following is the code −

import pandas as pd

# creating dataframe
dataFrame = pd.DataFrame({"Car": ['BMW', 'Lexus', 'Tesla', 'Mustang', 'Mercedes', 'Jaguar'],"Cubic_Capacity": [2000, 1800, 1500, 2500, 2200, 3000],"Reg_Price": [7000, 1500, 5000, 8000, 9000, 6000],"Units_Sold": [ 100, 120, 150, 110, 200, 250]
})

print"DataFrame ...\n",dataFrame

# reversing the dataframe columns
df = dataFrame[dataFrame.columns[::-1]]
print"\nReversed DataFrame....\n", df

Output

This will produce the following output −

DataFrame ...
        Car   Cubic_Capacity   Reg_Price   Units_Sold
0       BMW             2000        7000          100
1     Lexus             1800        1500          120
2     Tesla             1500        5000          150
3   Mustang             2500        8000          110
4  Mercedes             2200        9000          200
5    Jaguar             3000        6000          250
