Python-courses-python-exercises-python-list

Exercise 74

Write a Python program that replace the characters with odd index of a given string by '#'. Exemple if s = "Python" , the algorithm returns the string: "P#t#o#"

Solution

def replace(s):
    n = len(s)
    # initializing desired string
    new_string = ""
    
    # iterate over all characters of string s
    for i in range(0 , n):
        # adding the character of even index to the new string
        if( i%2 == 0 ):
            new_string = new_string + s[i]
        else:
            new_string = new_string + '#'
    return new_string

# Example
s = "Python"
print(replace(s)) # display : P#t#o#
