SYNTAX ERROR - Can't assign to operator in setting variables

问题

I have this Syntax Error in IDLE:

SyntaxError: can't assign to operator

This then highlights the end of a line, line 2 of the following code:

date              = "Unknown"
day-of-week       = "Unknown"     
time              = "Unknown"
week              = "Unknown"

I would appreciate any help I can get with this :)

回答1:

Python is interpreting day-of-week as "day" minus "of" minus "week". Try using day_of_week instead.

Sample code to show this.

>>> day = 3
>>> of = 2
>>> week = 4
>>> day-of-week
-3

回答2:

"Day-of-week" is an invalid variable name, and you can't use the minus sign on the left side of an assignment operation.

Your code is the equivalent of:

 day - of - week = "unknown"

Try

day_of_week = "unknown"

Instead!
