Solution Exercise 29: list of words containing at least one number

Exercise 29

Write a Python algorithm that determines the list of words containing at least one digit in a given T text.

Solution

# creation of a function which detects if a word contains a number or not
def digitInWord (word):
    counter = 0
    for x in word:
        if x.isdigit ():
            counter = counter + 1
    if counter> 0:
        return True
    else:
        return False

# creation of a function which returns the list of words containing at least one digit
def digitInText (T):
    # initialize the list of words containing at least one digit
    listWordWithNumber = []
    # convert text T to a list
    L = T.split ()
    for word in L:
        # we test if the word 'word' contains a number
        # using the digitInWord function defined previously
        if digitInWord (word):
            listWordWithNumber.append(word)
    return listWordWithNumber
# Example
T = "Python2.7 has been replaced by Python3.X since 2018"
print ("the list of words containing at least one digit is n", digitInText (T))
# the list returned is: ['Python2.7', 'Python3.X', '2018']
