Solution Exercise 65: Python algorithm which replaces the words in a list with their lengths.

Exercise 65

Given a list of strings, write a Python algorithm allowing which replace the elements of the list with their lengths. Example: if

 L = ["Python", "Django", "Numpy", "Sympy"]

, the algorithm returns the list

[6, 6, 5, 5]

Solution

def replaceByLength (L):
      # initialization of the searched list
      listLength = []
 
      # iterate over the elements of L and replace them with their lengths
      for word in L:
            listLength.append (len (word))
      return listLength
 
# Example
L = ["Python", "Django", "Numpy", "Sympy"]
print (replaceByLength (L)) # the output is: [6, 6, 5, 5]
