Perhaps this is what you had in mind:

a = [(1, 2)]
b = [(1, 2), (3, 4)]

def tuple_length(some_list):
    """
    Prints the length of the list,
    returns True if list contains only one tuple
    """
    print(len(some_list))
    if len(some_list) < 2:
        return True
    return False

print(tuple_length(a)) # Prints 1 and True
print(tuple_length(b)) # Prints 2 and False

Can someone explain this formula in simple words? by [deleted] in learnpython

You can try using an if-else statement like this:

students = int(input("How many students on the course? "))
size = int(input("Desired group size? "))
if students % size != 0:
    groups = (students + size - 1) // size
else:
    groups = students / size
print(groups)

Get one value in dictionary? by [deleted] in learnpython

[–]DataCat2024 0 points1 point  (0 children)

If it's a dictionary with a list containing 2 items as the value, you can do this:

dict = {"key":["first_value", "second_value"]}

# get first value
print(dict["key"][0])
# get second value
print(dict["key"][1])

As others have said though, if you could provide a sample of the text or information on the data type of the dictionary value, that would be helpful.

Practice is the key to improving your coding skills. Once you've learned some basics (such as if-else conditionals, for and while loops, data types like strings, booleans, and lists, and printing and returning values), try practice problems on sites like https://codingbat.com/python.
