'age': [20, 19, 22, 21],
'favorite_color': ['blue', 'red', 'yellow', "green"],
'grade': [88, 92, 95, 70]}
df = pd.DataFrame(raw_data, index = ['Willard Morris', 'Al Jennings', 'Omar Mullins', 'Spencer McDaniel'])
df
df = df[['favorite_color','grade','name','age']]
df.head()
Example 2: pandas reorder columns
df.columns
Index(['item1','item2','item3'], dtype='object')
cols = ['item3','item1','item2']
df = df[cols]
Example 3: rearrange columns pandas
You could also do something like this:
df = df[['mean', '0', '1', '2', '3']]
You can get the list of columns with:
cols = list(df.columns.values)
The output will produce:
['0', '1', '2', '3', 'mean']
