New submission from Miguel Brito <[email protected]>:
Hi, I was playing around with Python's grammar and noticed that the error
message for if expression is generic, so not very informative.
I decided to improve it slightly.
*From*:
```
>>> a = 42 if True
File "<stdin>", line 1
a = 42 if True
^
SyntaxError: invalid syntax
```
*To*:
```
$ ./python
Python 3.10.0b4 (tags/v3.10.0b4-dirty:2ba4b20854, Jul 31 2021, 11:50:15) [GCC
7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> a = 42 if True
File "<stdin>", line 1
a = 42 if True
^
SyntaxError: invalid syntax. Conditional expression expected an 'else' here.
```
