# Solution Exercise 91 **: python algorithm which move all words containing a number at the end of the list

Sep 16, 2021

#### Exercise 91 **

Write an algorithm in python as a function that transforms a string text T into a list where words containing numbers are placed at the end of the list. Example if T = "Python_1 created in 1991. Currently it is in version Python_3.9"the algorithm returns the list: ['created', 'in', 'Currently', 'it', 'is', 'in', 'version', 'Python_1', '1991.', 'Python_3.9' ]

#### Solution

``# function which tests if a given word contains a number or notdef digit_in_word (word):    # initialization of a counter    counter = 0    for x in word:        if x.isdigit():            counter = counter + 1                if counter > 0:        return True    else:        return False        # function which transforms a string into a list by moving all words containing numbers at the enddef moveDigit (T):    # transformation of the text string T into a list    L = T.split ()        # initialization of the list of words which do not contain any digits    L_without_digit = []        # initialization of the list of words which contain at least one digit    L_with_digit = []        # browse the elements of list L and find words that contain numbers    for word in L:        if digit_in_word (word):            L_with_digit.append (word)        else:            L_without_digit.append (word)                result = L_without_digit + L_with_digit                return result# ExampleT = "Python_1 created in 1991. Currently it is in version Python_3.9"print (moveDigit (T))# the output is:# ['created', 'in', 'Currently', 'it', 'is', 'in', 'version', 'Python_1', '1991.', 'Python_3.9']``
