Python String Exercise

Python string exercises are necessary for a beginner to understand the program and to have regular practice. Check out the article to know more about Python String Excercise.

What is the Python String?

In Python, you can make words or sentences by using either single quotes (‘) or double quotes (“). So, ‘hello’ and “hello” mean the same thing. It’s like choosing between two different types of containers for your words in Python.

What are the examples of Python Strings?

Let us look into the Python program provided below:

Example 1

Python Program to find the number of vowels in the given string.

def count_vowels(input_string):
    vowels = "aeiouAEIOU"
    count = 0

    for char in input_string:
        if char in vowels:
            count += 1

    return count

# Example usage:
input_string = "Hello, World!"
result = count_vowels(input_string)
print(f'The number of vowels in "{input_string}" is: {result}')

Output

The number of vowels in "Hello, World!" is: 3

Example 2:

Check this example to illustrate how the Python Program will convert the string with the binary digits to an integer.

def binary_to_decimal(binary_string):
    decimal_value = int(binary_string, 2)
    return decimal_value

# Example usage:
binary_string = "1101"
decimal_result = binary_to_decimal(binary_string)
print(f'The decimal equivalent of binary "{binary_string}" is: {decimal_result}')

Output

The decimal equivalent of binary "1101" is: 13

Example 3:

The example below has provided the Python Program to drop all digits from the string.

def remove_digits(input_string):
    result_string = ''.join(char for char in input_string if not char.isdigit())
    return result_string

# Example usage:
input_string = "Hello123World456"
result = remove_digits(input_string)
print(f'The string without digits: "{result}"')

Output

The string without digits: "HelloWorld"

Conclusion

To conclude, navigating through the Python String Exercise will equip you with valuable skills in handling text effortlessly. From understanding the basics of string manipulation to mastering various methods, you’ve laid a strong foundation for your coding journey.
