STEEM POWER retention ratio of top 50 witnesses

by joviansummer original STEEMIT post: https://steemit.com/blog/@joviansummer/steem-power-retention-ratio-of-top-50-witnesses Hello, this is @joviansummer(witness: @jswit). Some time ago there was a bit of discussion on discord witness chanel about witnesses' power-down/cashing-out. So out of curiosity I just checked current ratio of witnesses' own STEEM POWER(VESTS) and all-time producer reward(VESTS). The ratio is calculated by the following simple formula: ratio(%) = account's own SP(MV) / all-time producer reward SP(MV) * 100% Ratio value less than 100% indicates power-down. If witness does additional power-up or gets other types of reward(e.g., curation reward), the ratio may exceed 100%. This does not take witness' other accounts into consideration. All-time producer reward data is from @steemchiller's SDS API. Here is the result: rank account own_sp prod_sp ratio 1 justyy 2188.411MV 1284.2MV 170.41% 2 steemchiller 982.134MV 124...

파이썬의 print()에서 구분자 지정

파이선에서 print()로 출력할 때, 출력하는 값들 사이의 구분자(separator)를 지정해 줄 수 있습니다. 지정하지 않을 경우 기본 구분자는 공백입니다.

x = 1
y = 2
z = 3
print(x,y,z)

1 2 3

만약 출력하려는 값들 사이의 구분자를 콜론(:)으로 하고 싶다면 sep 옵션으로 지정합니다.

print(x,y,z,sep=':')

1:2:3

탭으로 구분하고 싶다면 아래와 같이 합니다.

print(x,y,z,sep='\t')

1 2 3

구분자를 없앨 수도 있습니다.

print(x,y,z,sep='')

123
