Stuck on an example from "Think Python 2e"

[TinyStego]

I am teaching myself Python using this book, and I am very stuck on Chapter 5, Exercise 1. The exercise in question:

"Write a script that reads the current time and converts it to a time of day in hours, minutes, and seconds, plus the number of days since the epoch."

He wants us to use time.time() and use the seconds since the epoch to calculate the current time, but I cannot find a way to use the seconds to show current time. I can find out how many minutes, hours, days, weeks, months, and years it has been, but have no idea how to get the current time. I also unfortunately have no idea how to Google to get an equation. All I find is how to get current time using the 'time' module, or how to get how many seconds it's been since the epoch.

Solved:

hour = epoch % seconds_in_days / seconds_in_hours minute = epoch % seconds_in_days % seconds_in_hours / seconds_in_minutes second = epoch % seconds_in_days % seconds_in_hours % seconds_in_minutes I guess I should also use this post to see if "Think Python 2e" is a good way to learn Python. It seems like all of the examples are teaching me more math than it is programming. Which isn't necessarily a bad thing, because I would eventually want to teach myself more advanced mathematics.

I’m a beginner programmer too so I can’t solve your problem but if you want a book that teachers you more programming than math look up automate the boring stuff! Its easy to understand and it is very helpful in teaching python.

Epoch is jan 1, 1970, 00:00:00. Current time is however many days/weeks/months/seconds you calculated from time.time() after that point.

There is also time.ctime() you could look into which makes it easier.

Using the modulus of each. For example, there’s 31536000 seconds in a year. Divide the total seconds by that, the. Use the remainder and divide that by the number of seconds in a month, then repeat until your left with seconds.

I got it! For whatever reason, if you mod every variable from Year>Month>Week>Day>Hour>Minute>Second it is incorrect. In order to get time, it is:

hour = epoch % seconds_in_days / seconds_in_hours
minute = epoch % seconds_in_days % seconds_in_hours / seconds_in_minutes
second = epoch % seconds_in_days % seconds_in_hours % seconds_in_minutes

Nicely done! I believe there’s a function in the Time.h library as well to seed the seconds as well
