我最近一直在研究一個項目,它從NOAA網站獲取METAR,並切割METAR數據並打印它。現在我遇到了問題,更改代碼以Python3.6
,當我嘗試.find()
那心滿意足的METAR數據的開始它給我這個錯誤消息的標記:.find()不帶字符串? Python 3.6
File "/Users/MrZeus/Desktop/PY3.6_PROJECT/version_1.py", line 22, in daMainProgram
data_start = website_html.find("<--DATA_START-->")
TypeError: a bytes-like object is required, not 'str'
我明白這是什麼錯誤說法。這意味着.find()
不接受字符串,但根據python文檔.find()
函數確實需要一個字符串!
這裏是我遇到的麻煩的一段代碼:
website = urllib.request.urlopen(airid)
website_html = website.read()
print(website_html)
br1_string = "<!-- Data starts here -->"
data_start = website_html.find(br1_string)
br1 = data_start + 25
br2 = website_html.find("<br />")
metar_slice = website_html[br1:br2]
print("Here is the undecoded METAR data:\n"+metar_slice)
謝謝sooooooo多! –
