# Pavan Kumpatla # December 10, 2021. # I learned about boolean operators and how to use them. # No difficulties.

# not operator print("not True = ", not True) # prints not True (False) print("not False = ", not False) # prints Not False (True)

# and operator print("False and False = ", False and False) # False and False = False print("False and True = ", False and True) # False and True = False print("True and False = ", True and False) # True and False = False print("True and True = ", True and True) # True and True = True

# or operator print("False or False = ", False or False) # False or False = False print("False or True = ", False or True) # False or True = True print("True or False = ", True or False) # True or False = True print("True or True = ", True or True) # True or True = True

print("True and not False =", True and not False) # prints, 1) Not False = True, 2) True 3) "= True" print("False or not True = ", False or not True) # prints, 1) Not True = False, 2) False, 3) "= False"

# [ ] Use relational and/or arithmetic operators with the variables x and y to write: # 3 expressions that evaluate to True (i.e. x >= y) # 3 expressions that evaluate to False (i.e. x <= y) x = 84 y = 17 # 3 expressions generating True print("True:- ") # prints print(x > y) # prints True or False (True) print(x >= y) # prints True or False (True) print(x == 84) # prints True or False (True) # 3 expressions generating False print("\n") # prints print("False:- ") # prints print(x < y) # prints True or False (False) print(x <= y) # prints True or False (False) print(x == "chocolate") # prints True or False (False)

# [ ] Use the basic Boolean operators with the variables x and y to write: # 3 expressions that evaluate to True (i.e. not y) # 3 expressions that evaluate to False (i.e. x and y) x = True y = False # 3 expressions generating True # True:- print(x and not y) # prints print(not y and x) # prints print(x or not y) # prints # 3 expressions generating False # False:- print("\n") # prints absolutely nothing, just a filter for space. print(x and y) # prints print(not y and not x) # prints print(not x and y) # prints

# Testing if x is outside the range [10, 20] x = 11 # stores value (x < 10) or (x > 20) # x is lesser than 10 or x is greater than 20, prints

# Testing if x is outside the range [10, 20] x = 50 # stores value (x < 10) or (x > 20) # x is lesser than 10 or x is greater than 20, prints

# Testing if x is a positive and odd number x = 11 # stores value (x > 0) and (x % 2 != 0) # x is greater and the remainder of x divided by 2 does not equal to 0, prints

# Testing if x is a positive and odd number x = -11 # stores value (x > 0) and (x % 2 != 0) # x is greater than 0 and the remainder of x divided by 2 does not equal to 0, prints

# Testing if x is a positive and odd number x = 22 # stores value in list (x > 0) and (x % 2 != 0) # x is greater than 0 and the remainder of x divided by 2 does not equal to 0, prints

# Driver information name = 'Colette' # stores value age = 17 # stores value # Testing if name starts with `C` and the age is 18 or less (name.startswith('C')) and (age <= 18) # name starts with C and age is lesser than or equal to 18

# Driver information name = 'John' # stores value age = 17 # stores value # Testing if name starts with `C` and the age is 18 or less (name.startswith('C')) and (age <= 18) # name starts with C and age is lesser than or equal to 18

# [ ] Write an expression to test if x is an even number outside the range [-100, 100] # Test your expression with: # x = 104 (True) # x = 115 (False) # x = -106 (True) # x = -99 (False) x = int(input("Type in a value for x:- ")) (x % 2 == 0) and ((x > 100) or (x < -100))

# [ ] Write an expression to test if a string s starts and ends with a capital letter # HINT: You might find the function `str.isupper()` useful # Test your expression with # s = "CapitaL" (True) # s = "Not Capital" (False) string = input("Enter String:- ") # stores user input string[-1].isupper() and string[0].isupper() # prints True or False if index 0 and -1 and is in uppercase

# [ ] Write an expression to test if a string s contains a numerical value # then test if the value is greater than the value stored in x # HINT: Use the functions `s.isnumeric()` and `float(s)` # Test your expression with # s = "39" # x = 24 # Expression should yield True # s = "a39" # x = 24 # Expression should yield False x = 24 # stores value in x s = input("Enter Number:- ") # stores user input if s.isnumeric(): # if s is numeric if float(s) > x: # if s, that is in float form, is greater than x print("Your number is greater than x!") # print this elif float(s) == x: # else if s, that is in float form, is equal to x print("Your number is the same as x!") # print this else: # else print("Your number is lesser than x.") # print this else: # else print("Please type in a number!") # print this

x = 11 # stores value (x >= 10) and (x <= 20) # x is greater than or equal to 10 # and # x is lesser than or equal to 20 # prints

x = 30 # stores value (x >= 10) and (x <= 20) # x is greater than or equal to 10 # and # x is lesser than or equal to x # prints

x = 11 # stores value not((x < 10) or (x > 20)) # x is lesser than 10 # or # x is greater than 20 # reverses whatever the final answer is # prints

x = 30 # stores value not((x < 10) or (x > 20)) # x is lesser than 10 # or # x is greater than 20 # reverses whatever the final answer is # prints

# [ ] Write an expression equivalent to the one below to # test if x is outside the range [10, 20] (seen in a previous example) # (x < 10) or (x > 20) # Test your expression with # x = 11 (False) # x = 50 (True) x = int(input("Type in a numerical value for x:- ")) # stores user input in int form not ((x > 10) and (x < 20)) # x is greater than 10 # and # x is lesser than 20 # reverses final answer # prints

# [ ] Write a second expression to test if x is an even number outside the range [-100, 100] # Do NOT use the expression you wrote for a previous exercise # Test your expression with: # x = 104 (True) # x = 115 (False) # x = -106 (True) # x = -99 (False) x = int(input("Type in a numerical value for x:- ")) # stores user input in int form ((x % 2 == 0) or ((x < -100) and (x > 100))) # there should be no remainder of x/2 # or # x is lesser than -100 # and # x is greater than 100

# Solicit user input x = input("Enter an odd positive number: ") # stores user input # Convert the string input into int x = int(x) # converts x to int form, stores # Test number for validity if ((x > 0) and (x % 2 != 0)): # if x is greater than 0 and the remainder of x/2 is not 0 print(x, "is a valid number") # print this else: # else print(x, "is NOT a valid number") # print this

# Solicit user input y = input("Enter your birth year: ") # stores user input # Convert the string input into int y = int(y) # converts to int form, stores # Check the decade membership if (y < 1970): # if y is lesser than 1970 print("You were born before 1970!") # print this elif (y >= 1970 and y < 1980): # else if y is greater than or equal to 1970 and is lesser than 1980 print("You were born in the 70s!") # print this elif (y >= 1980 and y < 1990): # else if y is greater than or equal to 1980 and y is lesser than 1990 print("You were born in the 80s!") # print this elif (y >= 1990 and y < 2000): # else if y is greater than or equal to 1990 and y is lesser than 2000 print("You were born in the 90s!") # print this elif (y >= 2000 and y < 2010): # else if y is greater than or equal to 2000 and y is lesser than 2010 print("You were born in early 2000s!") # print this else: # else print("You were born in the current decade!") # print this

# [ ] Write a program to validate that user input is outside the range [0, 100] x = int(input("Type in a number between 0-100:- ")) # stores user input in int form if x > 100 or x < 0: # if x is greater than 100 or x is lesser than 0 print("You have entered a number not within 0-100") # print this else: # else print("You have entered a number within 0-100") # print this

# [ ] Write a program to ask a user for her/his BMI index, then display the user's BMI category bmi = float(input("Enter your BMI Index:- ")) # stores user input in float form if bmi < 18.5: # if bmi is lesser than 18.5 print("Underweight") # print this elif bmi <= 24.9 and bmi >= 18.5: # else if bmi is lesser than 24.9 and is greater than 18.5 print("Normal Weight") # print this elif bmi <= 29.9 and bmi >= 25: # else if bmi is lesser than 29.9 and is greater than 25 print("Overweight") # print this elif bmi >= 30: # else if bmi is greater than or equal to 30 print("Obese") # print this else: # else print("Please Try Again!") # print this
