emumerate的问题，求各位帮帮忙

import csv

filename='sitka_weather_07-2014.csv'
with open(filename) as file:
        reader=csv.reader(file)
        header_row=next(reader)

        for index,column_header in emumerate(header_row):
                print(index,column_header)

报错：
Traceback (most recent call last):
  File "highs_lows2.py", line 8, in <module>
    for index,column_header in emumerate(header_row):
NameError: name 'emumerate' is not defined

我是按照书上的来写的，求大佬帮忙解决！
