Format String - NewPi - Oct-09-2022 Hey, I try to print some formatted integers with padded 0. But there is always a blank character in front of the print. My code is: num = 14 print(f"{num: 010d}")And my output is: 000000014 There are 9 digits and a blank character. Why is there a blank char and not only 10 digits? THX RE: Format String - deanhystad - Oct-10-2022 The space is there because you have a space in your format string. The space is what you should print as the sign for a positive number. num = 14 print(f"{num:010d}") # No prefix for positive numbers print(f"{-num:010d}") print(f"{num:+010d}") # + prefix for positive numbers print(f"{-num:+010d}") print(f"{num: 010d}") # space prefix for positive numbers print(f"{-num: 010d}")
RE: Format String - NewPi - Oct-10-2022 Oh, ok. Thanks for your answer. I didn't know, that the space between ':' and '0' counts. |
