这段文字在这个网站上似乎无法正确格式化,但是顶部的下面一行和底部的上面一行会导致 Unicode 错误。
以下是 os.popen 的代码示例。
>>> buffer = popen('10day', 'r').read()
Traceback (most recent call last):
File "/home/woodnt/python/10_day_forecast.py", line 129, in <module>
line_lower(51)
File "/home/woodnt/python/lib/box.py", line 24, in line_lower
print upper_line * len
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-50: ordinal not in range(128)
>>> print buffer
┌───────────────────────┐
│10 day weather forecast│
└───────────────────────┘
>>>
对于 subprocess.Popen,用法类似:
f = Popen('10day', stdout=PIPE, stdin=PIPE, stderr=PIPE)
o, er = f.communicate()
print o
┌───────────────────────┐
│10 day weather forecast│
└───────────────────────┘
print er
Traceback (most recent call last):
File "/home/woodnt/python/10_day_forecast.py", line 129, in <module>
line_lower(51)
File "/home/woodnt/python/lib/box.py", line 24, in line_lower
print upper_line * len

有没有什么想法,可以在不需要大量“底层”工作的情况下使其正常工作?我正在学习编程,并从Python开始。
