harmonic_mean() method का use दिए गए numeric data set harmonic mean (central location) calculate करता है।
Harmonic mean = data के reciprocals के arithmetic mean का reciprocal.
for example - अगर हमरे pass 4 values 2,3,4,5: हैं तो इनका harmonic mean : 4/(2/4 + 3/4 + 4/4 + 5/4) होगा।
statistics.harmonic_mean(data)
data | required : data जिसका हमें harmonic_mean calculate करना है , आप इसमें numeric values की list या कोई भी iterator (list, tuple, set) pass कर सकते हैं।
ध्यान रहे कोई भी negative value नहीं होनी चाहिए।
Return value : pass की गयी values के according float value return होती है।
# Import statistics module.
# Import statistics module.
import statistics
#pass data in list.
print('Calculate using list')
print(statistics.harmonic_mean([23,34,546,67]))
print(statistics.harmonic_mean([2,3,4,5]))
#pass data in tuple.
print('Calculate using tuple')
print(statistics.harmonic_mean((23,34,546,67)))
print(statistics.harmonic_mean((2,3,4,5)))
#pass data in set.
print('Calculate using set')
print(statistics.harmonic_mean({23,34,546,67}))
print(statistics.harmonic_mean({2,3,4,5}))
