Solution

The error message you're seeing is a Python syntax error. It's telling you that it expected a colon (":") at the end of your for loop declaration.

In Python, the syntax for a for loop is as follows:

for variable in iterable:
    # code to execute for each item in iterable

The colon at the end of the first line is mandatory. It tells Python that the code to be executed for each item in the iterable is coming up next.

So, your code should look something like this:

for i in range(len(rank)-1):
    if rank[i] > rank[i+1] and gifts[i] <= gifts[i+1]:
        # code to execute if condition is true

This code will iterate over the indices of the rank list (except the last one), and for each index i, it will check if the ith element of rank is greater than the i+1th element and if the ith element of gifts is less than or equal to the i+1th element. If both conditions are true, it will execute the code inside the if statement.
