How to change the order of Pandas DataFrame columns?

To change the order of DataFrame columns, we can take the following Steps −

Steps

• Make two-dimensional, size-mutable, potentially heterogeneous tabular data, df.

• Print the input DataFrame.

• Get the list of DataFrame columns, using df.columns.tolist()

• Change the order of DataFrame columns.

• Modify the order of columns of the DataFrame.

• Print the DataFrame after changing the columns order.

Example

import pandas as pd

df = pd.DataFrame(
   {
      "x": [5, 2, 1, 9],
      "y": [4, 1, 5, 10],
      "z": [4, 1, 5, 0]
   }
)
print "Input DataFrame is:<br>", df

cols = df.columns.tolist()
cols = cols[-1:] + cols[:-1]
df = df[cols]

print "After changing the order: <br>", df

Output

Input DataFrame is:
   x  y  z
0  5  4  4
1  2  1  1
2  1  5  5
3  9 10  0

After changing the order:
   z  x  y
0  4  5  4
1  1  2  1
2  5  1  5
3  0  9 10
