Can anyone improve my code for efficiency or suggest any other fast way than mine

Question

Write a function named format_number that takes a non-negative number as its only parameter.

Your function should convert the number to a string and add commas as a thousands separator.

For example, calling format_number(1000000) should return "1,000,000".

s = '{:,}'.format(num) # String Formatting
s = format(num, ',') # Built-in Format Function
print(s)

num = 123456789.45
print(f"{num:,}")
