    print("\t Player names and jersey numbers:")
    for element in astroRoster:
        print(f'{element["Name"]}: {element["PlayerNum"]}')

对于表格数据而言，熊猫是一个了不起的工具！打印数据，您可以使用下面的内容（未经测试）。您将需要对其进行修改以保存到文本文件。

import pandas as pd

df = pd.read_csv("yourcsv",names=["RowNum","PlayerNum","Name","Position","Age","ThrowHand","BatHand","Height","Weight","Birthdate","RookieYear"])
for row in df.rows:
   print row['Name'], row['PlayerNum'], row['Height']

如何从CSV文件的一行中抓取特定变量？
