我已将这些编程用于计算方差

import pandas as pd
import xlrd
import numpy as np
import matplotlib.pyplot as plt


credit_card=pd.read_csv("default_of_credit_card_clients_Data.csv",skiprows=1)

print(credit_card.head())
for col in credit_card:
    var[col]=np.var(credit_card(col))

print(var)

我收到了这个错误

回溯(最近一次调用最后一次):文件"C:/Python34/project.py",第11行,var [col] = np.var(credit_card(col))TypeError:'DataFrame'对象不可调用

一个解决方案将不胜感激.
