Day 31: Conditionals And If-Statements

 

# Conditionals in Python:
# <         less than 
# >         greater than 
# <=        equal or less 
# >=        equal or greater
# ==        equal to
# !=        not equal to
# is        identical object
# is not    Not identical object


number = input("Enter a number: ")

if (int(number)%2 == 0):
    print("Number is even")
else:
    print("Number is odd")

# the conditionals 'is' and 'is not'
name_1 = "matt"
name_2 = "tim"
name_3 = name_1

if (name_1 is name_3):                  # statement is true
    print("The same object!")

if (name_1 is not name_2):              # this statement is also true
    print("Two different objects!")
