SYNTAX ERROR - Can't assign to operator in setting variables
(2 answers)
Closed 3 years ago.
I got a SyntaxError: can't assign to operator when I typed in a boolean. How can I fixed it? Below is the code that popped a error:
Super-Sport = False
^
SyntaxError: can't assign to operator
I expect it will run smoothly, but it didn't
Change Super-Sport to Super_Sport (or SuperSport etc). Python is interpreting the - as minus and causing your syntax error.

How to create a formatted String out of a literal in Rust?
(2 answers)
Closed 4 months ago.
Is there a way to use String::from with variables? I tried using it similarly to println!(), but doesn't seem to work.
String::from("[INFO]: {}", message)
Expected:
// Returns: "[INFO]: My info message here"
Got:
// Error: argument unexpected
Rust doesn’t really practice variadic functions because we have big metaprogramming potential: modern generic system and about 6 types of macros.
In this case you need the format macro:
format!("[INFO]: {}", message)

Long Int literal - Invalid Syntax?

I'm trying to convert a small file from Python2 to Python3.
This hex variable assignment is blocking me.
a = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2FL
The error I'm receiving is:
a = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2FL
^
SyntaxError: invalid syntax
Any suggestions?
Is there a problem if you remove the L? Is that not the value you expect?
>>> 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F

sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 1, and there are 74 supplied
(2 answers)
Closed 4 years ago.
I am getting this error --
Incorrect number of bindings supplied The current statement uses 4,
and there are 3 supplied.
Here is the code --
def update_entry(self):
self.cur.execute('UPDATE SINGLE SET IN=?,OUT=?,QUALITY=? WHERE ID=?',
(self.IN_entry.get(),self.OUT_entry.get(),self.QC_entry.get()))
You have 4 placeholders in your query and yet you're supplying only 3 items in the tuple passed to execute. You should supply a value for the placeholder for ID as the 4th item in the tuple.

Does Python have a ternary conditional operator?
(31 answers)
Closed 5 years ago.
In java script there is an alternative to if statement i mean like ternary operator : (boolean expression )? option 1: option 2, it is elegant compact and sometimes less confusing. I have searched a lot to find an alternative for 'if' statement in python but i couldn't find anything. Is there any way to trick python so we can avoid if statement ?
If expression:
option1 if boolean_expression else option2
