原文:https://www.geesforgeks.org/get-list-of-column-header-from-a-pandas-data frame/
让我们看看如何将熊猫数据框的所有列标题作为一个列表。df.columns.values属性将返回一个列标题列表。
例 1 :
# importing pandas as pd
import pandas as pd
# creating the dataframe
df = pd.DataFrame({'PassengerId': [892, 893, 894, 895,
896, 897, 898, 899],
'PassengerClass': [1, 1, 2, 1, 3, 3, 2, 2],
'PassengerName': ['John', 'Prity', 'Harry',
'Smith', 'James', 'Amora',
'Kiara', 'Joseph'],
'Age': [32, 54, 71, 21, 37, 9, 11, 54]})
display("The DataFrame :")
display(df)
# print the list of all the column headers
display("The column headers :")
display(list(df.columns.values))
输出:
例 2 :
# importing pandas as pd
import pandas as pd
# creating the dataframe
my_df = {'Students': ['A', 'B', 'C', 'D'],
'BMI': [22.7, 18.0, 21.4, 24.1],
'Religion': ['Hindu', 'Islam',
'Christian', 'Sikh']}
df = pd.DataFrame(my_df)
display("The DataFrame :")
display(df)
# print the list of all the column headers
display("The column headers :")
display(list(df.columns.values))
输出:
