## comparison operators - takes num as input but gives bool as output
## logical operators: take bool value as input and gives bool as output
# AND: All the values have to be True to be True else its False
# True and True = True
# T and T and T and T and T and T and F = False
# OR: All the values have to be False to be False otherwise its True
## True or False = True
## control structure with logical operators, you mean multiple conditions
