Any Way To Add Zeros to Tens?

Question

So I'm writing a program that automatically timestamps Youtube videos, what I'm doing basically is getting a bunch of videos and putting them in one long video, so I have some code writted:

description = open("Description.txt", "r+")
description.truncate(0)
description.write("Timestamps:\n")
timestamps = [0.01, 0.08, 0.16, 0.30, 0.50, 1.05, 1.25] #These are just examples, usually this would be a list of 50 or so values
timeadd = 0
total = 0

for time in timestamps:
    timeadd += 1

for add in range(timeadd):
    total += timestamps[add]
    print(total)
    description.write(str(total) + "\n")

input("Done... ")

This works pretty successfully writes timestamps but any help to make this simpler would be appreciated, the problem is though it writes Timestamps like this: "2.1", what it means is "2:10", is there any way I could specify to add a 0 every time the Timestamp is in the tens place? I'm sorry if the answer is simple, I'm new to python.

One thing to consider with your script, you are adding numbers written in base 60, but doing math in base 10. For example, ```2:10 + 1:50 == 4```, but the way your script is running, you have ```2.1 + 1.50 == 3.6```. — goalie1998, Jan 28 '21 at 03:46

Quick suggestion, you can replace `for time in timestamps: timeadd += 1` (lines 8-9) with this `timeadd = len(timestamps)` — sushant_padha, Jan 28 '21 at 03:53
That question asks for adding zeros to the left, this one is to the right. — user202729, Jan 28 '21 at 03:54
Well there's [string - Display a float with two decimal places in Python - Stack Overflow](https://stackoverflow.com/questions/6149006/display-a-float-with-two-decimal-places-in-python) ;; however the underlying problem with op here is that float is not the suitable format in the first place. — user202729, Jan 28 '21 at 03:54
Well he also wants to replace the dot with a colon, just use two integers instead — Chayim Friedman, Jan 28 '21 at 03:55

I think you are going to have to store the timestamps as strings, if you want them to have this way. Ootherwise, you can store them as doubles and abuse a bit good ol' time module. Third way would be to write your own data object to store them the way you want.

To add zeroes to the number while displaying them, use this

number = 1.3  # example

print(number)  # Prints `1.3`

zero_padded_number = str(number).split('.')[0] + ':' + str(number).split('.')[1].ljust(2, '0')

print(zero_padded_number)  # Prints `1:30`

Note that zero_padded_number is a string, so it can only be used for printing and representation purposes.
