使用python2进行数据清理

Question

在我的代码中，我需要使用$删除def符号，并需要将它们转换为numbers以进行计算。

def remove_dollar(s):
    """Removes dollar signs and spaces from s.
    Returns it as a float.
    """
    # YOUR CODE HERE
    s = sales(s)
    s.remove('$')
    return ''.join(s)
remove_dollar(sales['LastSpend'])

Answer 1

您可以尝试：

用空字符串替换$。

 s = s.replace('$',"")

完整功能：

def remove_dollar(s):
    """Removes dollar signs and spaces from s.
    Returns it as a float.
    """
    # YOUR CODE HERE
    s = sales(s)
    s = s.replace('$',"")
    return s
remove_dollar(sales['LastSpend'])
