# Noemi Cabrera # September 27, 2021 # In this lesson, I learned to use comparison operators in if conditionals. This makes it easier for the code to # make decisions based on the input. The comparision operators are placed on the if statement. If the # condition is true, the if statement will display. If it's not true, the else statement will display. # I didn't have any difficulties in this activity. # However, when I did the last task I forgot to put a colon at the end of the if statement, so a syntax error # displayed. To fix this, I just added a colon at the end of the if statement.

# [ This code uses the comparison operator(>) to evaluate if 3 is greater than 5. # Since 3 is not greater than 5, False is displayed.] review and run code 3 > 5

# [ This code uses the comparison operator (<=) to evaluate if 3 less than or equal to 5. # Since 3 is less than 5, True is displayed. ] review and run code 3 <= 5

# [ This code assings the variable x the value of 3 using a single equal sign. Then x is evaluated to see if it # equals to 9 by using 2 equal signs. This displays False, since x is not equal to 9. ] review and run code x = 3 x == 9

# [ This code uses the comparison operators =! and == to evaluate if x is not equal to 9 and if x is equal to 3. # Since x is not equal to 9 and equal to 3, True is displayed for both statements. ] review and run code x = 3 print("x not equal 9 is", x != 9) print("x equal 3 is", x == 3)

# [This code assings x a value. Then it displays True if x is equal to 13 and False if x is not equal to 13.] x = 11 print("x is equal to 13 : ",x == 13)

# [This code assings a value to y and d. Then these are compared to see if y is greater than d. # This displays to false because y is not greater than d.] y= 3+3 d= 2+4 print ("3 + 3 is greater than 2 + 4 : ", y > d)

# [This code uses the (>) comparison operator in an if conditional. If x is greater than 25, the if statement will # display. But if x is not greater than 25, the else statement will display.] review code and run cell x = 21 if x > 25: print("x is already bigger than 25") else: print("x was", x) x = 25 print("now x is", x)

# [ This code uses the == comparison operator in an if conditional. The variable x is assigned 18. If x + 18 is # equal to x + x, then the if statement will print. If this is not true, the else statement will print.] # review code and run cell x = 18 if x + 18 == x + x: print("Pass: x + 18 is equal to", x + x) else: print("Fail: x + 18 is not equal to", x + x)

# [ In this code, the if statement tests if x is not equal to the variable test_value. # Since x is equal to 18 and test_value is also equal to 18, the else statement will print.] # review code and run cell. "!" means "not" x = 18 test_value = 18 if x != test_value: print('x is not', test_value) else: print('x is', test_value)

# [ This code displays a syntax error because the single equal sign is misused. The variable x is assigned 2 by # using the single equal sign. However, in the if statement x is meant to be compared so you have to use the double # equal sign (==).] review code and run cell # DON'T ASSIGN (x = 2) when you mean to COMPARE (x == 2) x = 2 if x = 2: print('"==" tests for, is equal to') else: pass

# This code contains an if/else stament. If y is greater than x+x, the if statement will display. # If y is not greater than x+x, the else statement will display. x = 3 y = x + 8 if y >= x+x: print("y greater than or equal x + x is True") else: print("y greater than or equal x + x is False")
