If all the conditions of the “OR” operator are not satisfied, then the code associated with the “else” block will execute. Output: The output shows that one of the initialized values is the same. Example 3: Using OR Operator With Python elif Statement ...

Learn Python list comprehension, and its syntax and example, using if-else style conditions and writing nested list comprehensions involving two lists.
We run the example a few times. The if statement can start with a short statement to execute before the condition. main.go package main import ( "fmt" "math/rand" ) func main() { if num := -5 + rand.Intn(10); num > 0 { fmt.Println("value is positive") } else if num =...
