Before you keep reading...

Runestone Academy can only continue if we get support from individuals like you. As a student you are well aware of the high cost of textbooks. Our mission is to provide great books to you for free, but we ask that you consider a $10 donation, more if you can or less if $10 is a burden.

Before you keep reading...

Making great stuff takes time and $$. If you appreciate the book you are reading now and want to keep quality materials free for other students please consider a donation to Runestone Academy. We ask that you consider a $10 donation, but if you can give more thats great, if $10 is too much for your budget we would be happy with whatever you can afford as a show of support.

Put the blocks in order to define the function has22 to return True if there are at least two items in the list nums that are adjacent and both equal to 2, otherwise return False. For example, return True for has22([1, 2, 2]) since there are two adjacent items equal to 2 (at index 1 and 2) and False for has22([2, 1, 2]) since the 2’s are not adjacent.

        def has22(nums):
---
    for i in range(len(nums)-1):
---
    for i in range(len(nums)): #paired
---
        if nums[i] == 2 and num[i+1] == 2:
---
        if nums[i] == 2 and num[i-1] == 2: #paired
---
            return True
---
            return true #paired
---
    return False
        

Finish the function has22 below to return True if there are at least two items in the list nums that are adjacent and both equal to 2, otherwise return False. For example, return True for has22([1, 2, 2]) since there are two adjacent items equal to 2 (at index 1 and 2) and False for has22([2, 1, 2]) since the 2’s are not adjacent.

def has22(nums): ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(has22([1, 2, 2]), True, 'has22([1, 2, 2])') self.assertEqual(has22([1, 2, 1, 2]), False, 'has22([1, 2, 1, 2])') self.assertEqual(has22([2, 1, 2]), False, 'has22([2, 1, 2])') self.assertEqual(has22([2, 2, 1]), True, 'has22([2, 2, 1])') self.assertEqual(has22([3, 4, 2]), False, 'has22([3, 4, 2])') self.assertEqual(has22([2]), False, 'has22([2])') self.assertEqual(has22([]), False, 'has22([])') self.assertEqual(has22([3, 3, 1]), False, 'has22([3, 3, 1])') self.assertEqual(has22([1, 4, 4]), False, 'has22([1, 4, 4])') myTests().main()

What is printed when the following statements execute?

day = "Thursday"
day = 32.5
day = 19
print(day)

• Nothing is printed. A runtime error occurs.
• It is legal to change the type of data that a variable holds in Python.
• Thursday
• This is the first value assigned to the variable day, but the next statements reassign that variable to new values.
• 32.5
• This is the second value assigned to the variable day, but the next statement reassigns that variable to a new value.
• 19
• The variable day will contain the last value assigned to it when it is printed.

True or False: the following is a legal variable name in Python: A_good_grade_is_A+

• True
• - The + character is not allowed in variable names.
• False
• - The + character is not allowed in variable names (everything else in this name is fine).
