19. join()

The join() function lets you merge string items in a list.

You only need to specify a delimiter and the target list to use it:

a = ["Python", "tutorial", "on", "MUO"]
a = " ".join(a)
print(a)

Output: Python tutorial on MUO

20. replace()

Python's replace() method lets you replace some parts of a string with another character. It's often handy in data science, especially during data cleaning.
The replace() method accepts two parameters: the replaced character and the one you'll like to replace it with.

Here's how it works:

columns = ["Cart_name", "First_name", "Last_name"]
for i in columns:
 i = i.replace("_", " ")
 print(i)

Output:
Cart name
First name
Last name

What is the difference between append() and extend() methods?

Both append() and extend() methods are methods used to add elements at the end of a list.

👉append(element): Adds the given element at the end of the list that called this append() method

👉extend(another-list): Adds the elements of another list at the end of the list that called this extend() method

Six Steps to Defining a Function

1. What should your function do? Type a couple of example calls.
2. Pick a meaningful name (often a verb or verb phrase): What is a short answer to "What does
your function do"?
3. Decide how many parameters the function takes and any return values
4. Describe what your function does and any parameters and return values in the docstring
5. Write the body of the function
6. Test your function. Think about edge cases.
