Task 7 - String methods

Python gives every string a toolbox of built-in methods. You call a method with dot notation, for example my_text.upper().

Below are a few handy ones to get you started. For the complete reference, see the official list on W3Schools (or similar sites on the web): https://www.w3schools.com/python/python_ref_string.asp

Quick demo

sample = "  Python programming  "

print(sample.strip())          # remove leading and trailing spaces
print(sample.lower())          # all lowercase
print(sample.upper())          # ALL UPPERCASE
print(sample.count("m"))       # how many times 'm' appears
print(sample.replace("Python", "Java"))  # swap words
print(sample.startswith("  P"))          # True or False
print("gram" in sample)        # membership test (True)

Each method returns a new string (or a number/boolean) - the original stays unchanged unless you reassign it.

Your exercise

1. Create a file called Task_6.py.

2. Add a variable quote and set it to a short sentence of your choice.

3. Use at least four different string methods on quote, printing the result of each. Suggestions:

   • title()
   • find()
   • replace()
   • endswith()
   • encode()

4. After each call, print the original quote again to show it has not changed.

5. Finally, print a one-line comment (using #) summarizing which method you found most useful.

Run the file and compare your output with the documentation page to see what each method does.
