Python: Replace all but the last five characters of a given string into "*" and returns the new masked string

Python Basic - 1: Exercise-90 with Solution

Mask All But Last Five Characters

Write a Python program that replaces all but the last five characters of a string with "*" and returns the modified string.

Sample Solution:

Python Code:

# Define a function named new_string that takes a string (str1) as an argument.
def new_string(str1):
    # Create a new string composed of '*' repeated (len(str1) - 5) times, followed by the last 5 characters of the original string.
    return '*' * (len(str1) - 5) + str1[-5:]
	
# Test the function with different strings and print the results.

# Test case 1
text = "kdi39323swe"
# Print the original string.
print("Original String: ", text)
# Print the new string generated by the function.
print("new string: ", new_string(text))

# Test case 2
text = "12345abcdef"
# Print the original string.
print("\nOriginal String: ", text)
# Print the new string generated by the function.
print("new string: ", new_string(text))

# Test case 3
text = "12345"
# Print the original string.
print("\nOriginal String: ", text)
# Print the new string generated by the function.
print("new string: ", new_string(text))

Sample Output:

Original String:  kdi39323swe
new string:  ******23swe

Original String:  12345abcdef
new string:  ******bcdef

Original String:  12345
new string:  12345

Explanation:

Here is a breakdown of the above Python code:

• Function definition:
• The code defines a function named "new_string()" that takes a string (str1) as an argument.
• String Composition:
• The function creates a new string by concatenating '*' repeated (len(str1) - 5) times and the last 5 characters of the original string (str1[-5:]).
• Test cases:
• The function is tested with different strings, and the original strings along with the new strings are printed.
