Generate sequence 10, 20, 50, 100, 200 ... 5,000,000,000,000,000,000,000

Question

The R code that generates this sequence seems very beautiful.How you would generate the sequence in your language of choice?Full sequence: 10 20 50 100 200 500 1000 2000 5000 10000 20000 50000 100000 200000 500000 1000000 2000000 5000000 10000000 20000000 50000000 100000000 200000000 500000000 1000000000 2000000000 5000000000 10000000000 20000000000 50000000000 100000000000 200000000000 500000000000 1000000000000 2000000000000 5000000000000 10000000000000 20000000000000 50000000000000 100000000000000 200000000000000 500000000000000 1000000000000000 2000000000000000 5000000000000000 10000000000000000 20000000000000000 50000000000000000 100000000000000000 200000000000000000 500000000000000000 1000000000000000000 2000000000000000000 5000000000000000000 10000000000000000000 20000000000000000000 50000000000000000000 100000000000000000000 200000000000000000000 500000000000000000000 1000000000000000000000 2000000000000000000000 5000000000000000000000 R code:options(scipen=99);(rep(c(1,2,5), 10) * (10 ^ (sort(rep(1:30, 3)))))[1:63]

I think it looks quite elegant in Python if you use the modern f-strings and pragmatic inline calculations. >>> for i in range(21): ... print(f"{10*10**i:>23}{20*10**i:>23}{50*10**i:>23}") ... 10 20 50 100 200 500 1000 2000 5000 10000 20000 50000 100000 200000 500000 1000000 2000000 5000000 10000000 20000000 50000000 100000000 200000000 500000000 1000000000 2000000000 5000000000 10000000000 20000000000 50000000000 100000000000 200000000000 500000000000 1000000000000 2000000000000 5000000000000 10000000000000 20000000000000 50000000000000 100000000000000 200000000000000 500000000000000 1000000000000000 2000000000000000 5000000000000000 10000000000000000 20000000000000000 50000000000000000 100000000000000000 200000000000000000 500000000000000000 1000000000000000000 2000000000000000000 5000000000000000000 10000000000000000000 20000000000000000000 50000000000000000000 100000000000000000000 200000000000000000000 500000000000000000000 1000000000000000000000 2000000000000000000000 5000000000000000000000 >>> Edit: fixed the asterisks for HN formatting

I'm amazed at how many people who build graphs never learned the very basic rule that used to be taught in freshman engineering classes: Unless there is a really good reason, always scale the axes of your graphs using a range from the 1,2,5,10... sequence. (e.g., With a max Y-axis value of 38, graph on a scale maxing at 50, 1546 on 2000, etc).Since most data science developers are not engineers, we see a lot of crap graphs these days...
