Abbreviates an integer number with K, M, B, T for thousands, millions,
|
||
|
|
billions and trillions, respectively.
|
||
|
|
Examples:
|
||
|
|
>>> get_human_readable_count(123)
|
||
|
|
'123 '
|
||
|
|
>>> get_human_readable_count(1234) # (one thousand)
|
||
|
|
'1 K'
|
||
|
|
>>> get_human_readable_count(2e6) # (two million)
|
||
|
|
'2 M'
|
||
|
|
>>> get_human_readable_count(3e9) # (three billion)
|
||
|
|
'3 B'
|
||
|
|
>>> get_human_readable_count(4e12) # (four trillion)
|
||
|
|
'4 T'
|
||
|
|
>>> get_human_readable_count(5e15) # (more than trillion)
|
||
|
|
'5,000 T'
|
||
|
|
Args:

number: a positive integer number
|

Return:
|

|
|
A string formatted according to the pattern described above.
