如何确定 python 中 csv 文件中列的数据类型？

Question

I am trying to determine the data type of all the columns in a csv file. The code is:

df = pd.read_csv('accepted.csv')
for name, dtype in df.dtypes.iteritems():
        print("Column Name: ",name," ||| ","Data Type : ", dtype)

Now the problem I am facing is that it gives float64 for most of the columns and 0 for some. How can I get the original data type?

@Gandharv this code is working fine, i got the correct data types for each features However you can directly view the datatypes using.dtypes(): This returns a Series with the data type of each column. Why do you need to use for loop for this since we've a function to do it.
