描述
Bug report
Bug description:
The doc says starred target as shown below:
*Memo:
- The doc also says
star_target.
If the target list contains one target prefixed with an asterisk, called a “starred” target:
But using multiple starred targets on the left side of = gets the error message saying starred expressions instead of starred targets as shown below:
*v1, *v2, *v3 = [0, 1, 2, 3, 4]
# Error
SyntaxError: multiple starred expressions in assignment
So, the error message should say starred targets as shown below:
SyntaxError: multiple starred targets in assignment
And, using a single starred target on the left side of = gets the error message saying starred assignment target as shown below:
*v = [0, 1, 2, 3, 4]
SyntaxError: starred assignment target must be in a list or tuple
So, the error message should say starred target as shown below:
SyntaxError: starred target must be in a list or tuple in assignment
