python - Pandas 使用值计数获取类型

Question

# col is a series
t = col.apply(type).value_counts()
t_count = zip(t.index, t)

我的结果是t.index是<type 'int'> 。我如何确定这个类型是int。基本上我想要这样的东西

<type 'int'> == type(int) #It is returning false currently but i would like it to return true without converting it to a str and processing it

您可以与int进行比较:

col =  pd.Series([1,2,'a','d','d',1.5,7.8])
t = col.apply(type).value_counts() 
print (t)
<class 'str'>      3
<class 'float'>    2
<class 'int'>      2
dtype: int64

print (t.index == int)
[False False  True]

print (t[t.index == int])
<class 'int'>    2
dtype: int64

也可以比较系列:

print (col.apply(type) == int)
0     True
1     True
2    False
3    False
4    False
5    False
6    False
dtype: bool

print (col[col.apply(type) == int])
0    1
1    2
dtype: object
