Solution Exercise 91: python programme to find the list of common word with maximum length within a given to string text

Exercise 91 ***

Write a python algorithm which determines the common words with maximum length of two strings text T1 and T2. Example if: T1 = "Python created by Guidorossum is open source programming language. Python was created on 1991"and T2 = "Python created by Guidorossum is the most popular programming language Guidorossum", the algorithm returns the list:

['Guidorossum', 'programming']

Solution

#creating a method which determines the list of common words in T1 and T2
def commonWords(T1 , T2):
    # converting the texts into lists
    listWords_in_T1 = T1.split()
    listWords_in_T2 = T2.split()

    # initializing the common words
    listCommon_words = []
    for word in listWords_in_T1 :
        if word in listWords_in_T2 and word not in listCommon_words:
            listCommon_words.append(word)
    return listCommon_words

# Creating a methode that determines the common word with maximum length
def commonMax(T1, T2):
    listCommon_words = commonWords(T1 , T2)
    # initializing the maximum length
    maxLength = 0
    for word in listCommon_words:
        if len(word) >= maxLength:
            maxLength = len(word)
            
    # searching the the common words of maximum length
    listCommonWordMax = []
    for word in listCommon_words:
        if len(word) == maxLength:
            listCommonWordMax.append(word)
    return listCommonWordMax

T1 = "Python created by Guidorossum is open source programming language. Python was created on 1991"
T2 = "Python created by Guidorossum is the most popular programming language Guidorossum"
print(commonMax(T1 , T2))
# The output is: ['Guidorossum', 'programming']
