的Python Beautifulsoup：file.write（STR）方法来获取类型错误：写（）参数必须海峡，不BeautifulSoup

Question

我写了下面的代码：

from bs4 import BeautifulSoup 
import sys # where is the sys module in the source code folder ? 

try: 
    import urllib.request as urllib2 
except ImportError: 
    import urllib2 


print (sys.argv) # 
print(type(sys.argv)) # 

#baseUrl = "https://ecurep.mainz.de.xxx.com/ae5/" 
baseUrl = "http://www.bing.com" 
baseUrl = "http://www.sohu.com/" 
print(baseUrl) 

url = baseUrl 
page = urllib2.urlopen(url) #urlopen is a function, function is also an object 
soup = BeautifulSoup(page.read(), "html.parser") #NameError: name 'BeautifulSoup' is not defined 

html_file = open("Output.html", "w") 
soup_string = str(soup) 
print(type(soup_string)) 
html_file.write(soup_string) # TypeError: write() argument must be str, not BeautifulSoup 
html_file.close() 

该编译器在下面的错误:(但soup_string显然是一个？海峡，为什么由编译器 也给出了第一个错误不知道为什么第二个出现）

C:\hzg>py Py_logDownload2.py 1 
['Py_logDownload2.py', '1'] 
<class 'list'> 
http://www.sohu.com/ 
<class 'str'> 
Traceback (most recent call last): 
    File "Py_logDownload2.py", line 25, in <module> 
    html_file.write(soup_string) # TypeError: write() argument must be str, not 
BeautifulSoup 
    File "C:\Users\ADMIN\AppData\Local\Programs\Python\Python35\lib\encodings\ 
cp1252.py", line 19, in encode 
    return codecs.charmap_encode(input,self.errors,encoding_table)[0] 
UnicodeEncodeError: 'charmap' codec can't encode characters in position 376-377: 
character maps to <undefined> 

更重要的是混乱，如果我改变代码：

baseUrl = "https://ecurep.mainz.de.xxx.com/ae5/" 
#baseUrl = "http://www.bing.com" 
#baseUrl = "http://www.sohu.com/" 

它会编译并且没有错误。 （我把原来的名字改为“xxx”）。

任何人都可以帮助调试吗？

-----更新：

我以前写Java代码或我为Python新手。在你的帮助下，我想我已经在调试Python方面取得了一些进展：在调试Java时，总是尝试解决第一个错误;而在Python中，ayways试图解决最后一个问题。对？

尝试打开你的文件，utf-8

import codecs 
f = codecs.open("test", "w", "utf-8") 

可以忽略编码错误（不推荐）由

f = codecs.open("test", "w", "utf-8", errors='ignore')
