Python open（）函数在Spyder中不起作用，但在具有相同解释器的终端中起作用

Question

Hi I am having some issues with trying to run a very simple program in Spyder:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
"""

"""

f = open('shark-species.txt')

for line in f:
    print(line)

The .txt file contains only letters from the latin alphabet. The error I am getting when running in spyder IPython or Python console is:

Traceback (most recent call last):

File "<ipython-input-5-eccaeae0c773>", line 1, in <module>
runfile('/Users/admin/pybin/LCPWP/Chapter4/sharkspecies.py', 
    wdir='/Users/admin/pybin/LCPWP/Chapter4')

File "/Users/admin/anaconda/lib/python3.5/site-
packages/spyder/utils/site/sitecustomize.py", line 880, in runfile
    execfile(filename, namespace)

File "/Users/admin/anaconda/lib/python3.5/site-
packages/spyder/utils/site/sitecustomize.py", line 102, in execfile
    exec(compile(f.read(), filename, 'exec'), namespace)

File "/Users/admin/pybin/LCPWP/Chapter4/sharkspecies.py", line 11, in 
<module>
for line in f:

File "/Users/admin/anaconda/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 0xc3 in position 
7869: ordinal not in range(128)

Now the weird thing is that the program runs just fine from the terminal and both Spyder and the terminal are using the same interpreter so I'm really struggling to see why Spyder is doing this. At the bootom of the screen in Spyder it also explicitly says coding is UTF-8.

Answer 1

The file does contain Unicode characters, the preferred way to open files is it by using the codecs module as it follows:

 import codecs

 with codecs.open('file', 'r', 'utf-8') as fp:
      lines = fp.readlines()
