初学Python,debug时报错,不知道原因在哪?

Question

在pycharm下编写的.
报错信息如下:

C:\Python27\python.exe "C:\Program Files\JetBrains\PyCharm 2017.1.2\helpers\pydev\pydevd.py" --multiproc --qt-support --client 127.0.0.1 --port 51755 --file E:/python/first.py
pydev debugger: process 4988 is connecting

Connected to pydev debugger (build 171.4249.47)
Traceback (most recent call last):
  File "C:\Program Files\JetBrains\PyCharm 2017.1.2\helpers\pydev\pydevd.py", line 1585, in <module>
    globals = debugger.run(setup['file'], None, None, is_module)
  File "C:\Program Files\JetBrains\PyCharm 2017.1.2\helpers\pydev\pydevd.py", line 1015, in run
    pydev_imports.execfile(file, globals, locals)  # execute the script
  File "E:/python/first.py", line 3
SyntaxError: Non-ASCII character '\xe7' in file E:/python/first.py on line 3, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

Process finished with exit code 1

后来自己回忆了下,是我大意了..记得第一次debug的时候,

是要修改下图圈内的文件路径的,当我修改完文件路径之后,程序可以运行了.
所以每次创建新程序debug的时候,都要手动在这里修改文件路径吗?

Answer 1

编码的问题，在第一行加上
# coding:utf-8

如果是Linux系统，
#!/usr/bin/env python
# coding:utf-8

Answer 2

File "E:/python/first.py", line 3
SyntaxError: Non-ASCII character 'xe7' in file E:/python/first.py on line 3, but no encoding declared;

这里的问题，第三行，中文解码错误，是不是用了中文的标点符号

Answer 3

SyntaxError: Non-ASCII character '\xe7' in file E:/python/first.py on line 3, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

根据错误信息，去提示的官网可以找到出错的原理，主要是因为Python在默认状态下不支持源文件中的编码,

依上图提示可以在文件第一行这样加一句：

# coding=utf-8

Answer 4

在代码的最开始加 -- coding:gb2312 --

Answer 5

代码中用了中文逗号，换成英文格式就好。提示里有指出。
