是否可以通过点表示法而不是括号表示法访问Series项目?
s = pandas.Series(dict(a=4, b=4))
print s['a'] # works
print s.a # fails
正如我们可以使用DataFrame:
df = pandas.DataFrame([dict(a=4, b=4), dict(a=4, b=4)])
print df['a'] # works
print df.a # works

我通过重载Series .__ get_attr__方法来获取行为:
def my__getattr__(self, key):
# If attribute is in the self Series instance ...
if key in self:
# ... return is as an attribute
return self[key]
else:
# ... raise the usual exception
raise AttributeError("'Series' object has no attribute '%s'" % key)
# Overwrite current Series attributes 'else' case
pandas.Series.__getattr__ = my__getattr__
然后我可以使用属性访问Seriee项目:
xx = pandas.Series(dict(a=44, b=55))
xx.a

不可能。您可以将系列转换为单列DataFrame。
