使用Python搜索/抓取craigslist

Question

我想在所有（美国）craigslist中搜索特定查询“救护车”，然后返回结果。

我正在使用以下脚本：https://github.com/juliomalegria/python-craigslist

以下是城市列表：https://github.com/jhemperl/US-Craigslist-cities/blob/master/US-craigslist-cities

这是我第一次尝试使用python：

# define empty list
sites = []

# open file and read the content in a list
with open('US-craigslist-cities.txt', 'r') as filehandle:  
    filecontents = filehandle.readlines()

    for line in filecontents:
        # remove linebreak which is the last character of the string
        current_place = line[:-1]

        # add item to the list
        sites.append(current_place)
from craigslist import CraigslistForSale
for item in sites:
    cl_h = CraigslistForSale(site=(item),category='cta',
                         filters={'query': 'ambulance', 'max_price':5000})

for result in cl_h.get_results(sort_by='newest'):
    print result
