Python 从单一输入更改为列表会导致错误

Question

有人可以解释“如何/为什么”发生以下错误吗？

单一输入代码

PASTED_CRM_DATA = "13 HOADLEY ST MAWSON ACT 2607"
URL_LIST = 'https://www.realestate.com.au/property/' + str(PASTED_CRM_DATA.replace(' ', '-').lower()),

结果:抓取 URL 1 of 1 https://www.realestate.com.au/property/13-hoadley-st-mawson-act-2607

但是当转换为列表时

PASTED_CRM_DATA = ["13 HOADLEY ST MAWSON ACT 2607",
"13 HOADLEY ST MAWSON ACT 2607"
]
URL_LIST = 'https://www.realestate.com.au/property/' + str(PASTED_CRM_DATA.replace(' ', '-').lower()),

结果:AttributeError:'list'对象没有属性'replace'

理论上我理解这个错误，但是如何克服对象无法格式化列表内文本的问题？

Answer 1

.replace 是字符串，对于列表你需要循环并逐一替换

PASTED_CRM_DATA = ["13 HOADLEY ST MAWSON ACT 2607",
"13 HOADLEY ST MAWSON ACT 2607"]
URL_LIST = ['https://www.realestate.com.au/property/' + x.replace(' ', '-').lower() for x in PASTED_CRM_DATA]

print(URL_LIST)

# ['https://www.realestate.com.au/property/13-hoadley-st-mawson-act-2607', 
#  'https://www.realestate.com.au/property/13-hoadley-st-mawson-act-2607']
