如何在 pandas dataframe 的表中获取所有列名称及其索引号？

Question

I would like to remove certain columns of a dataframe and found it annoying typing all the column names. I would like to use columns index numbers instead of columns to remove the columns from the dataframe. The following code gives all the header names but how to get index numbers too?

import pandas as pd
df=pd.read_csv("https://raw.githubusercontent.com/codebasics/py/master/ML/14_naive_bayes/titanic.csv")
print(df.columns)

Expected Output:

'PassengerId', 0
 'Name', 1
 'Pclass', 2
 'Sex', 3
 'Age', 4
 'SibSp', 5
 'Parch', 6
 'Ticket', 7
 'Fare', 8
 'Cabin', 9
 'Embarked', 10
 'Survived', 11

Answer 1

Use pd.Series with columns names:

s = pd.Series(df.columns)
print (s)
0     PassengerId
1            Name
2          Pclass
3             Sex
4             Age
5           SibSp
6           Parch
7          Ticket
8            Fare
9           Cabin
10       Embarked
11       Survived
dtype: object

Like mentioned @timgeb (thank you) is possible select by positions instead columns names:

df['Name']
df.iloc[:, 1]

---

If need remove first 2 columns use:

df = df.iloc[:, 2:]

Answer 2

To print both index number and column name you can use enumerate :

>>> list(enumerate(df.columns))
