Python - 从 Pandas 输出中消除索引值

Question

CODE SAMPLE

import pandas as pd
data = pd.read_csv('file_name.csv',parse_dates=True)
print(data['EmpName'])

Output:

**0**     Tim K
**1**     Joesph R
**2**     Don T
**3**     Rachel P
**4**     Sam W

Want to eliminate index values from the output?

Answer 1

If you want to print out a list of names use:

for i in data['EmpName']:
    print(i)

Outputs:

Tim K
Joseph R
...

If you need the data in a list use:

new_list = list(data['EmpName'])

Final note

Print statement formatting is somewhat arbitrary. Usually the print function is used to test objects during development. You should familiarize yourself with common python objects such as lists, tuples, numpy arrays and pandas dataframes, to enable you to manipulate data effectively.

Answer 2

data['EmpName'] is a Pandas Series. If you do list([data['EmpName']) , that will print it out as a list; it will be enclosed in brackets and the elements will be separated with commas. So it will look like this: ['Tim K', 'Joesph R', 'Don T', 'Rachel P', 'Sam W'] . If you don't want the commas, you can do ' '.join(data['EmpName']) and that will give 'Tim K Joesph R Don T Rachel P Sam W' . Note that if any of the elements are not string-type (eg some are int), that will give an error, so to be safe you might want to do ' '.join([name for name in data['EmpName']])
