For more information on f-strings, take a look at PEP 498 where they were introduced.

Nicolas GervaisNicolas Gervais 30.4k11 gold badges101 silver badges126 bronze badges This is how I do it:
Basically zfill takes the number of leading zeros you want to add, so it's easy to take the biggest number, turn it into a string and get the length, like this: Python 3.6.5 (default, May 11 2018, 04:00:52) [GCC 8.1.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> total = 100 >>> print(str(1).zfill(len(str(total)))) 001 >>> total = 1000 >>> print(str(1).zfill(len(str(total)))) 0001 >>> total = 10000 >>> print(str(1).zfill(len(str(total)))) 00001 >>>

How do you add zeros after a number in Python?How to add leading zeros to a number in Python. print(a_number). number_str = str(a_number) Convert `a_number` to a string.. zero_filled_number = number_str. zfill(5) Pad `number_str` with zeros to 5 digits.. print(zero_filled_number). How do you put a zero in front of a string in Python?Python String zfill() Method
The zfill() method adds zeros (0) at the beginning of the string, until it reaches the specified length. If the value of the len parameter is less than the length of the string, no filling is done.
What .2f means in Python?A format of . 2f (note the f ) means to display the number with two digits after the decimal point. So the number 1 would display as 1.00 and the number 1.5555 would display as 1.56 .
How do you not remove leading zeros in Python?Here's what you are looking for: with open('numbers','w') as f: # open a file (automatically closes) for x in range(10000): # x = 0 to 9999 f. write('{:05}\n'. format(x)) # write as a string field formatted as width 5 and leading zeros, and a newline character.
