Изменить порядок столбцов Pandas DataFrame в Python
Опубликовано: 27 Марта, 2022
Давайте посмотрим, как изменить порядок столбцов DatFrame.
Алгоритм:
- Создайте DatFrame.
- Переназначьте тот же DataFrame с измененным порядком столбцов.
- Распечатайте DataFame.
Example 1 :
# importing the modulesimport pandas as pdimport numpy as np # creating the DataFramemy_data = {"Sr.no": [1, 2, 3, 4, 5], "Name": ["Ram", "Sham", "Sonu", "Tinu", "Monu"], "Maths Score": [45, 67, 89, 74, 56]}df = pd.DataFrame(data = my_data) # printing the original DataFrameprint("My Original DataFrame")print(df) # altering the DataFramedf = df[["Sr.no", "Maths Score", "Name"]] # printing the altered DataFrameprint("After altering Name and Maths Score")print(df) |
Output:
Example 2 :
# importing the modulesimport pandas as pd # creating the DataFramel1 =["Amar", "Barsha", "Carlos", "Tanmay", "Misbah"]l2 =["Alpha", "Bravo", "Charlie", "Tango", "Mike"]l3 =[23, 25, 22, 27, 29]l4 =[69, 54, 73, 70, 74]df = pd.DataFrame(list(zip(l1, l2, l3, l4))) df.columns =["Name", "Code", "Age", "Weight"] # printing the original DataFrameprint("My Original DataFrame")print(df) # altering the DataFramedf = df[["Name", "Code", "Weight", "Age"]] # printing the altered DataFrameprint("After altering Weight and Age")print(df) |
