Can someone explain me about these lines?

Question

set_9 = {1,2,3,4,5}
for a in set_9:
    print(f"{a:>6.2f}")

Output

  1.00
  2.00
  3.00
  4.00
  5.00

1. Is :> an operator? If not, what type is it?

2. What is 6.2f mean?

Answer 1

The format used is called Formatted string literals or f-strings, which is f"{a:>6.2f}"

Anything inside the curly braces is replacement field, which is {a:>6.2f}

Here, a is the field_name and >6.2f is the format_spec.

replacement_field::= "{" [field_name] [":" conversion] [":" format_spec] "}"

Expanding the format specification used in your example:

• > - align - Right align the field

• 6 - width - Minimum width (by default space is used as fill character)

• .2 - precision - Number of digits after the decimal point

• f - type - Floating point notation
