Python-courses-python-exercises

Exercise 35

Write a python algorithm as a function which takes as parameter a string text T and which returns the list of words containing at least one number and one capital letter. Example: if T = 'Python2.7 has been replaced by Python3.X since 2018', the algorithm return: ['Python2.7', 'Python3.X']

Solution

# creating a function which calculates the number of digits on a string
def number_digit (s):
    # initialization of the number of digits
    nbrDigit = 0
    for x in s:
        if x.isdigit ():
            nbrDigit = nbrDigit + 1
    return nbrDigit

# creation of a function which calculates the number of capital letters in a string
def number_maj (s):
    # initializing the number of capitals
    nbrMaj = 0
    for x in s:
        if x.isupper ():
            nbrMaj = nbrMaj + 1
    return nbrMaj
    
# creating a function which returns the list of words containing at least one number and one uppercase
def listMajDigits (s):
    # initialization of the searched words list
    listWord = []
    # convert string s to a list
    L = s.split ()
    for word in L:
        if number_digit (word)> 0 and number_maj (word)> 0:
            listWord.append (word)
    return listWord

# Example
T = "Python2.7 has been replaced by Python3.X since 2018"
print (listMajDigits (T)) # the output is: ['Python2.7', 'Python3.X']
