To illustrate, the example below shows a toy function that checks the length of a string object: Python >>> def validate_length(string): ... if (n := len(string)) < 8: ... print(f"Length {n} is too short, needs at least 8") ... else: ... print(f"Length {n} is...
For example, if inputs = [1, 2, 3, 4, 5, 6] and n = 2, your function should return [(1, 2), (3, 4), (5, 6)].Taking a naive approach, you might write something like this:Python def naive_grouper(inputs, n): num_groups = len(inputs) // n return [tuple(inputs[...

Using theformatfunction, we can use all the power of python’s string formatting tools on the data. In this case, we use${0:,.2f}to place a leading dollar sign, add commas and round the result to 2 decimal places. For example, if we want to round to 0 decimal places, we can ch...

Create a Regex object with the re.compile() function. (Remember to use a raw string.) Pass the string you want to search into the Regex object’s search() method. This returns a Match object. Call the Match object’s group() method to return a string of the actual matched text.NOTE...
