UPDATE:Sorting a list from a for output from highest to lowest in python
for x in letters:
frequency[x]+=1
for x in frequency:
print x,frequency[x],frequency[x]/float(n)
Sorry but I'm fairly new to programming and everything and I'm trying to get the output to be sorted from highest value of frequency[x]/float(n)
to lowest value. Is there any method of being 开发者_开发百科able to sort it just through the printing command?
Thanks very much!
For the keys:
sorted(frequency, key=lambda x: frequency[x], reverse=True)
Do
for x in sorted(frequency, key=lambda y: frequency[y]/float(n), reverse=True):
print x,frequency[x],frequency[x]/float(n)
This should do the trick:
freqs = sorted([frequency[x]/float(n) for x in frequency], reverse=True)
If you want it more like the print statement you have above, try this:
for (fxn, fx, x) in sorted([(frequency[x]/float(n), frequency[x], x) for x in frequency], reverse=True):
print x, fx, fxn
Answers flashing right before my eyes! Yes, use sorted
