error name 'dtype' is not defined

I try to compile this code but I get this errror : 

NameError: name 'dtype' is not defined

Here is the python code : 

# -*- coding: utf-8 -*-
from __future__ import division
import pandas as pd
import numpy as np
import re
import missingno as msno
from functools import partial
import seaborn as sns
sns.set(color_codes=True)


if dtype(data.OPP_CREATION_DATE)=="datetime64[ns]":
    print("OPP_CREATION_DATE is of datetime type")
else:
    print("warning: the type of OPP_CREATION_DATE is not datetime, please fix this")

Any idea please to help me to resolve this problem? Thank you

I have just realized that I could have used:

from pandas.api.types import is_string_dtype, is_numeric_dtype

As written by Amr Keleg,

If data is a pandas dataframe then you can check the type of a column as follows:
df['colname'].dtype or df.colname.dtype

In that case you need e.g.

df['colname'].dtype ==  np.dtype('datetime64')

or 

df.colname.dtype ==  np.dtype('datetime64')

You should use type instead of dtype.

type is a built-in function of python - https://docs.python.org/3/library/functions.html#type

On the other hand, If data is a pandas dataframe then you can check the type of a column as follows:
df['colname'].dtype or df.colname.dtype
