python3 文件读写，编码错误UnicodeDecodeError

问题：python3 with open文件进行读写，报编码错误

/usr/local/Cellar/python3/3.5.2/Frameworks/Python.framework/Versions/3.5/lib/python3.5/encodings/ascii.py, line 26, in decode

return codecs.ascii_decode(input, self.errors)[0]

UnicodeDecodeError: \'ascii\' codec can\'t decode byte 0xe7 in position 478: ordinal not in range(128)

 

代码如下：

with open("../testsuit/temptestcaseslist.txt","w") as f:
    f.write(content)

 

解决方法：

with open()中增加参数【encoding=‘utf-8’】指定读写文件的编码格式

 

with open("../testsuit/temptestcaseslist.txt","w",encoding='utf-8') as f:
    f.write(content)
