Hey there! Let's get your code working properly and make it even cleaner. First, let's break down the two main issues in your current code:

1. Index Out-of-Bounds Error #

Python lists use 0-based indexing—meaning the first element is at position 0, not 1. When you use range(1,11), your loop variable x goes from 1 to 10. But your list only has indices from 0 to 9 (since there are 10 elements), so list[10] will throw an IndexError.

2. Syntax Error in Print Statement #

You're missing an operator to combine the list element with the rest of the string. You need either a + for string concatenation or a comma to separate print arguments.

Solution 1: Use enumerate() (Most Pythonic Way) #

The enumerate() function was made exactly for this scenario—it lets you loop through a list and get both the element and its position (with an optional starting number). Here's how to use it:

names = ['Francisco', 'Marcelle', 'Olivia', 'José', 'Guilherme', 'Maria', 'Arthur', 'Lucas', 'Lurdes', 'Antonio']
# Start numbering from 1 instead of the default 0
for number, name in enumerate(names, start=1):
    print(f"{name}, your number on the list is {number}.")

Solution 2: Fix Your Original range() Approach #

If you want to stick with range(), adjust the index to match 0-based indexing and fix the print syntax:

names = ['Francisco', 'Marcelle', 'Olivia', 'José', 'Guilherme', 'Maria', 'Arthur', 'Lucas', 'Lurdes', 'Antonio']
# Loop from 0 to 9 (since len(names) is 10)
for x in range(len(names)):
    # The displayed number is x + 1, and we use string concatenation correctly
    print(names[x] + ", your number on the list is " + str(x + 1) + ".")
    # Alternatively, use f-strings for cleaner formatting (same result):
    # print(f"{names[x]}, your number on the list is {x+1}.")

Why These Work: #

• enumerate(names, start=1) pairs each name with a number starting at 1, so you don't have to do manual index math.
• range(len(names)) ensures we only loop through valid indices (0 to 9), and x + 1 converts the 0-based index to the human-friendly 1-based numbering you want.
• F-strings (f"...") make string formatting way easier to read and write than concatenation with +.

Both solutions will output exactly what you want:

Francisco, your number on the list is 1.
Marcelle, your number on the list is 2.
...
Antonio, your number on the list is 10.
