Handling Multiple Character Removal

strip() can remove multiple characters, but only from the beginning and end of the string:

my_str = '*$@*Python@$*'
print(my_str.strip('*$@'))  # Output: 'Python'

Use Case: Cleaning User Input

When processing form data or reading from files, strip() can help remove unwanted whitespace:

user_input = '  John Doe  '
clean_input = user_input.strip()
print(clean_input)  # Output: 'John Doe'

Removing Leading and Trailing Dots

Use strip() to clean up special characters at the ends of a string:

my_str = '...Python...'
print(my_str.strip('.'))  # Output: 'Python'

Use Case: Trimming Whitespace from File Input

When reading lines from a file, strip() is helpful to remove trailing newlines or extra spaces:

with open('data.txt', 'r') as file:
    for line in file:
        clean_line = line.strip()
        print(clean_line)

Difference between strip(), lstrip(), and rstrip()

strip() removes characters from both sides, while lstrip() and rstrip() remove characters from the left and right respectively:

text = "  Hello World  "
print(text.lstrip())  # Output: "Hello World  "
print(text.rstrip())  # Output: "  Hello World"
