For loops#

1. Fill the missing pieces#

Fill the ____ parts in the code below.

words = ['PYTHON', 'JOHN', 'chEEse', 'hAm', 'DOE', '123']
upper_case_words = []

for ____ in words:
    if ____.isupper():
        ____.append(____)

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[1], line 6
      4 for ____ in words:
      5     if ____.isupper():
----> 6         ____.append(____)

AttributeError: 'str' object has no attribute 'append'

assert upper_case_words == ['PYTHON', 'JOHN', 'DOE']

2. Calculate the sum of dict values#

Calculate the sum of the values in magic_dict by taking only into account numeric values (hint: see isinstance).

magic_dict = dict(val1=44, val2='secret value', val3=55.0, val4=1)

# Your implementation
sum_of_values =     

assert sum_of_values == 100

3. Create a list of strings based on a list of numbers#

The rules:

  • If the number is a multiple of five and odd, the string should be 'five odd'

  • If the number is a multiple of five and even, the string should be 'five even'

  • If the number is odd, the string is 'odd'

  • If the number is even, the string is 'even'

numbers = [1, 3, 4, 6, 81, 80, 100, 95]

# Your implementation
my_list = 

assert my_list == ['odd', 'odd', 'even', 'even', 'odd', 'five even', 'five even', 'five odd']
