The leader took credit for it. I changed the variable name and laid him off

Today I will introduce you to a new variable name е.

hi , This is not e Well ？ What do you deny , Play with me .

Don't make complaints about it. , Let me show you a wave of code .

Type "help", "copyright", "credits" or "license" for more information.
>>> е = 1024
>>> e
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'e' is not defined
>>> 

Clearly, the variable has been defined e, Why not defined Wrong. ？？

I have a picture as proof , This is not what I changed to make everyone happy ,

as a result of е Not the one we know ‘ Billion ’. It is a Slavic character .

What about? , It's impossible to distinguish by visual inspection ？

>>> ord('e')
101
>>> ord('е')
1077

See the difference ？

So if we put e Change to е Words , Think about the consequences .

Postscript

There are few cases where a single letter is used as a variable name , Then we can mix it with other English letters .

This Bug The investigation must be very sour .
