python - 尝试在 Python 中使用 Pandas 删除逗号和美元符号

Question

删除列中的逗号和美元符号。但是当我这样做时，表格会将它们打印出来并且仍然在那里。是否有其他方法可以使用 pandas 函数删除命令和美元符号。我无法在 API Docs 中找到任何内容，或者我找错地方了

 import pandas as pd
    import pandas_datareader.data as web

players = pd.read_html('http://www.usatoday.com/sports/mlb/salaries/2013/player/p/')


df1 = pd.DataFrame(players[0])


df1.drop(df1.columns[[0,3,4, 5, 6]], axis=1, inplace=True)
df1.columns = ['Player', 'Team', 'Avg_Annual']
df1['Avg_Annual'] = df1['Avg_Annual'].replace(',', '')

print (df1.head(10))

Answer 1

您必须根据 http://pandas.pydata.org/pandas-docs/stable/text.html 访问 str 属性

df1['Avg_Annual'] = df1['Avg_Annual'].str.replace(',', '')
df1['Avg_Annual'] = df1['Avg_Annual'].str.replace('$', '')
df1['Avg_Annual'] = df1['Avg_Annual'].astype(int)

交替;

df1['Avg_Annual'] = df1['Avg_Annual'].str.replace(',', '').str.replace('$', '').astype(int)

如果您想优先考虑打字时间而不是可读性。
