Remove Vowels from String

Write a Python program to remove all vowels from a given string.

Sample Solution-1:

Python Code:

# Import the 're' module for regular expressions.
import re

# Define a function 'test' that removes vowels from a given text using regular expressions.
def test(text):
    # Use the 're.sub' function to replace vowels (case-insensitive) with an empty string.
    return re.sub(r'[aeiou]+', '', text, flags=re.IGNORECASE)

# Provide a sample text "Python".
text = "Python"
# Print the original text.
print("Original string:", text)
# Print the result after removing vowels from the sample text using the 'test' function.
print("After removing all the vowels from the said string: " + test(text))

# Provide another sample text "C Sharp".
text = "C Sharp"
# Print the original text.
print("\nOriginal string:", text)
# Print the result after removing vowels from the sample text using the 'test' function.
print("After removing all the vowels from the said string: " + test(text))

# Provide one more sample text "JavaScript".
text = "JavaScript"
# Print the original text.
print("\nOriginal string:", text)
# Print the result after removing vowels from the sample text using the 'test' function.
print("After removing all the vowels from the said string: " + test(text))

Sample Output:

Original string: Python
After removing all the vowels from the said string: Pythn

Original string: C Sharp
After removing all the vowels from the said string: C Shrp

Original string: JavaScript
After removing all the vowels from the said string: JvScrpt

Explanation:

Here is a breakdown of the above Python code:

• Import Statement:
• The 're' module is imported for regular expression operations.
• Test Function (test function):
• The "test()" function is defined to remove vowels from a given text using regular expressions (re.sub).
• The regular expression [aeiou]+ matches one or more vowels (case-insensitive), and they are replaced with an empty string.

Sample Solution-2:

Python Code:

# Define a function 'test' that removes vowels from a given text.
def test(text):
    # Define a string containing all vowels (both uppercase and lowercase).
    vowels = "AEIOUaeiou"
    # Use a list comprehension to create a new string without vowels.
    return ''.join(el for el in text if not el in vowels)

# Provide a sample text "Python".
text = "Python"
# Print the original text.
print("Original string:", text)
# Print the result after removing vowels from the sample text using the 'test' function.
print("After removing all the vowels from the said string: " + test(text))

# Provide another sample text "C Sharp".
text = "C Sharp"
# Print the original text.
print("\nOriginal string:", text)
# Print the result after removing vowels from the sample text using the 'test' function.
print("After removing all the vowels from the said string: " + test(text))

# Provide one more sample text "JavaScript".
text = "JavaScript"
# Print the original text.
print("\nOriginal string:", text)
# Print the result after removing vowels from the sample text using the 'test' function.
print("After removing all the vowels from the said string: " + test(text))

Sample Output:

Original string: Python
After removing all the vowels from the said string: Pythn

Original string: C Sharp
After removing all the vowels from the said string: C Shrp

Original string: JavaScript
After removing all the vowels from the said string: JvScrpt

Explanation:

Here is a breakdown of the above Python code:

• Test Function (test function):
• The "test()" function is defined to remove vowels from a given text.
• A string 'vowels' is defined to contain all vowels (both uppercase and lowercase).
• A list comprehension is used to create a new string without vowels.
