The“typeerror: bad operand type for unary -: ‘list'”is a common error that occurs when you’re trying to use the unary minus (-) operator on a list, which is not a valid operation. In addition to that, this error happens when Python encounters an incompatible operand type for the ...
Here, we assigned 10 to variable x and -20 to variable y, when we print the value of both variables using Unary minus operator, the result is -x= 10 and -y= 20.3) Increment (++) Operator This operator increases the value by 1; there are two varieties of increment operator 1) pre...
The unary minus operator is used to negate a number, and when it is used before a variable, it negates its value. The unary minus operator represents the prefix-sign in C++. You must put the-sign before a number to negate it; for example, if you want to negate 5, you will type ...
