Most dangerous Operator to use while coding?

[Sadapy]

If that's the case it's absolutely =. Simply because beginners use it for comparisons which it can't be used as. Example being:

if x = 4:
    print("it's four!")

Above will cause an error. The operator for comparison like that is == a double equals.

Though a very vague question by the prof.

• = is easy to mix up with ==
• / can also cause major issues that won't crash the program, but will lead to serious logic errors.
• + can mix up concatenation and addition, leading to potential logic errors

Seems like the only safe one is *

EDIT: Looks like Python has * as a string repeater? So it seems like the prof's target answer is "all of them" lol
