Solution Exercise 96 * : python algorithm that returns words that contain more than one capital letter

Exercise 96 *

Write an algorithm in Python as a function which takes a text string as parameter and which returns the list of words containing at least two uppercase letters. Example if
 s = 'The PySide GUI library is more popular than PyQt'
, the function returns the list:
['GUI', 'PySide', 'PyQt']

Solution

# create a function that returns the number of uppercase letters in a string
def numberMaj (s):
    # define and initialize a variable which counts the number of capitals letters
    counter = 0

    # browsing through all characters of the string s
    for x in s:
        # increment the counter each time the character encountered is in uppercase
        if x.isupper():
            counter = counter + 1
    return counter

# Function which returns the list of words which contain at least 2 capital letters
def wordsTwoUppercase (s):
    # initialization of the list of words that contains at least 2 capital letters
    listTwoShift = []
    
    # convert string s to a list
    L = s.split ()
    
    #  browsing through all words in list L
    for word in L:
        # test if the 'word' element contains a capital letter or not
        if numberMaj(word) >= 2:
            listTwoShift.append (word)
    return listTwoShift

# Example
s = 'PySide GUI library is more popular than PyQt'
print ("The list of words with at least 2 capitals is:", wordsTwoUppercase(s))
# The output is:
# The list of words with at least 2 capitals is: ['PySide', 'GUI', 'PyQt']
