Solution Exercise 94 *: python algorithm which tests if the first character is identical to the last

Exercise 94 *

Write a Python algorithm which extract from a string text the list of words whose first character is identical to the last. Example if s = "radar number 212", the algorithm returns the list ['radar', '212']

Solution

# function which tests if the first character is identical to the last
def first_end (s):
    if s [0] == s [-1]:
        return True
    else:
        return False
    
# Function which determines the list of words whose first character is identical to the last
def list_first_end (s):
    # convert the string s to a list:
    L = s.split()
    # initialization of the searched list
    l_first_end = []
    
    for word in L:
        if first_end (word):
            l_first_end.append (word)
    return l_first_end

# Example
s = "radar number 212"
print ("The searched list is:", list_first_end (s))
# The output is: The searched list is: ['radar', '212']
