Python Exercises: Replace a word with hash characters in a string

Python String: Exercise-103 with Solution

Write a Python program to replace each character of a word of length five and more with a hash character (#).

Sample Solution-1:

Python Code:

def test(text):
	for i in text.split():
		if len(i) >= 5:
			text = text.replace(i, "#" * len(i))
	return text

text ="Count the lowercase letters in the said list of words:"
print("Original string:", text)
print("Replace words (length five or more) with hash characters in the said string:")
print(test(text))
text = "Python - Remove punctuations from a string:"
print("\nOriginal string:", text)
print("Replace words (length five or more) with hash characters in the said string:")
print(test(text))

Sample Output:

Original string: Count the lowercase letters in the said list of words:
Replace words (length five or more) with hash characters in the said string:
##### the ######### ####### in the said list of ######

Original string: Python - Remove punctuations from a string:
Replace words (length five or more) with hash characters in the said string:
###### - ###### ############ from a #######

Flowchart:

Flowchart: Add two strings as they are numbers (Positive integer values).

Sample Solution-2:

Python Code:

def test(text):
    return ' '.join('#' * len(i) if len(i) >= 5 else i for i in text.split(' '))
text ="Count the lowercase letters in the said list of words:"
print("Original string:", text)
print("Replace words (length five or more) with hash characters in the said string:")
print(test(text))
text = "Python - Remove punctuations from a string:"
print("\nOriginal string:", text)
print("Replace words (length five or more) with hash characters in the said string:")
print(test(text))

Sample Output:

Original string: Count the lowercase letters in the said list of words:
Replace words (length five or more) with hash characters in the said string:
##### the ######### ####### in the said list of ######

Original string: Python - Remove punctuations from a string:

Python: Tips of the Day

Enum Class:

Here is another classy approach from Python, no pun intended. Python's enum class will let you create enum object members with constant and unique values which then can be listed, compared or used for identification.

Enum classes are also iterable so they can be iterated as well:

from enum import Enum
class sports(Enum):
    volleyball = 1
    soccer = 2
    running = 3
    football = 4
    baseball = 5
    boxing = 6
print(sports.baseball)
print(repr(sports.baseball))

Output:

sports.baseball
<sports.baseball: 5>
